17 INTRODUCTION TO ARCNET
18 ----------------------
20 ARCnet is a network type which works in a way similar to popular Ethernet
21 networks but which is also different in some very important ways.
23 First of all, you can get ARCnet cards in at least two speeds: 2.5 Mbps
24 (slower than Ethernet) and 100 Mbps (faster than normal Ethernet). In fact,
25 there are others as well, but these are less common. The different hardware
26 types, as far as I'm aware, are not compatible and so you cannot wire a
27 100 Mbps card to a 2.5 Mbps card, and so on. From what I hear, my driver does
28 work with 100 Mbps cards, but I haven't been able to verify this myself,
29 since I only have the 2.5 Mbps variety. It is probably not going to saturate
30 your 100 Mbps card. Stop complaining. :)
32 You also cannot connect an ARCnet card to any kind of Ethernet card and
35 There are two "types" of ARCnet - STAR topology and BUS topology. This
36 refers to how the cards are meant to be wired together. According to most
37 available documentation, you can only connect STAR cards to STAR cards and
38 BUS cards to BUS cards. That makes sense, right? Well, it's not quite
39 true; see below under "Cabling."
41 Once you get past these little stumbling blocks, ARCnet is actually quite a
42 well-designed standard. It uses something called "modified token passing"
43 which makes it completely incompatible with so-called "Token Ring" cards,
44 but which makes transfers much more reliable than Ethernet does. In fact,
45 ARCnet will guarantee that a packet arrives safely at the destination, and
46 even if it can't possibly be delivered properly (ie. because of a cable
47 break, or because the destination computer does not exist) it will at least
48 tell the sender about it.
50 Because of the carefully defined action of the "token", it will always make
51 a pass around the "ring" within a maximum length of time. This makes it
52 useful for realtime networks.
54 In addition, all known ARCnet cards have an (almost) identical programming
55 interface. This means that with one ARCnet driver you can support any
56 card, whereas with Ethernet each manufacturer uses what is sometimes a
57 completely different programming interface, leading to a lot of different,
58 sometimes very similar, Ethernet drivers. Of course, always using the same
59 programming interface also means that when high-performance hardware
60 facilities like PCI bus mastering DMA appear, it's hard to take advantage of
61 them. Let's not go into that.
63 One thing that makes ARCnet cards difficult to program for, however, is the
64 limit on their packet sizes; standard ARCnet can only send packets that are
65 up to 508 bytes in length. This is smaller than the Internet "bare minimum"
66 of 576 bytes, let alone the Ethernet MTU of 1500. To compensate, an extra
67 level of encapsulation is defined by RFC1201, which I call "packet
68 splitting," that allows "virtual packets" to grow as large as 64K each,
69 although they are generally kept down to the Ethernet-style 1500 bytes.

72 advantages) of ARCnet networks, you might try the "ARCnet Trade Association"

78 -----------------------
80 This section was rewritten by
81 Vojtech Pavlik <vojtech@suse.cz>
82 using information from several people, including:
83 Avery Pennraun <apenwarr@worldvisions.ca>
84 Stephen A. Wood <saw@hallc1.cebaf.gov>
85 John Paul Morrison <jmorriso@bogomips.ee.ubc.ca>
86 Joachim Koenig <jojo@repas.de>
87 and Avery touched it up a bit, at Vojtech's request.
89 ARCnet (the classic 2.5 Mbps version) can be connected by two different
90 types of cabling: coax and twisted pair. The other ARCnet-type networks
91 (100 Mbps TCNS and 320 kbps - 32 Mbps ARCnet Plus) use different types of
92 cabling (Type1, Fiber, C1, C4, C5).
94 For a coax network, you "should" use 93 Ohm RG-62 cable. But other cables
95 also work fine, because ARCnet is a very stable network. I personally use 75
98 Cards for coax cabling are shipped in two different variants: for BUS and
99 STAR network topologies. They are mostly the same. The only difference
100 lies in the hybrid chip installed. BUS cards use high impedance output,
101 while STAR use low impedance. Low impedance card (STAR) is electrically
102 equal to a high impedance one with a terminator installed.
104 Usually, the ARCnet networks are built up from STAR cards and hubs. There
105 are two types of hubs - active and passive. Passive hubs are small boxes
106 with four BNC connectors containing four 47 Ohm resistors:
110 -R-+-R- R 47 Ohm resistors
114 The shielding is connected together. Active hubs are much more complicated;
115 they are powered and contain electronics to amplify the signal and send it
116 to other segments of the net. They usually have eight connectors. Active
117 hubs come in two variants - dumb and smart. The dumb variant just
118 amplifies, but the smart one decodes to digital and encodes back all packets
119 coming through. This is much better if you have several hubs in the net,
120 since many dumb active hubs may worsen the signal quality.
122 And now to the cabling. What you can connect together:
124 1. A card to a card. This is the simplest way of creating a 2-computer
127 2. A card to a passive hub. Remember that all unused connectors on the hub
128 must be properly terminated with 93 Ohm (or something else if you don't
129 have the right ones) terminators.
130 (Avery's note: oops, I didn't know that. Mine (TV cable) works
133 3. A card to an active hub. Here is no need to terminate the unused
134 connectors except some kind of aesthetic feeling. But, there may not be
135 more than eleven active hubs between any two computers. That of course
136 doesn't limit the number of active hubs on the network.
138 4. An active hub to another.
140 5. An active hub to passive hub.
142 Remember, that you can not connect two passive hubs together. The power loss
143 implied by such a connection is too high for the net to operate reliably.
145 An example of a typical ARCnet network:
148 S------H--------A-------S R - Terminator
156 The BUS topology is very similar to the one used by Ethernet. The only
157 difference is in cable and terminators: they should be 93 Ohm. Ethernet
158 uses 50 Ohm impedance. You use T connectors to put the computers on a single
159 line of cable, the bus. You have to put terminators at both ends of the
160 cable. A typical BUS ARCnet network looks like:
162 RT----T------T------T------T------TR
169 But that is not all! The two types can be connected together. According to
170 the official documentation the only way of connecting them is using an active
173 A------T------T------TR
179 The official docs also state that you can use STAR cards at the ends of
180 BUS network in place of a BUS card and a terminator:
182 S------T------T------S
185 But, according to my own experiments, you can simply hang a BUS type card
186 anywhere in middle of a cable in a STAR topology network. And more - you
187 can use the bus card in place of any star card if you use a terminator. Then
188 you can build very complicated networks fulfilling all your needs! An
193 RT------T-------T------H------S
196 S------A------T-------T-------A-------H------TR
200 S------H---A----S | |
201 | | S------T----H---S |
204 A basically different cabling scheme is used with Twisted Pair cabling. Each
205 of the TP cards has two RJ (phone-cord style) connectors. The cards are
206 then daisy-chained together using a cable connecting every two neighboring
207 cards. The ends are terminated with RJ 93 Ohm terminators which plug into
208 the empty connectors of cards on the ends of the chain. An example:
210 ___________ ___________
213 |Card | |Card | |Card |
214 |_____| |_____| |_____|
217 There are also hubs for the TP topology. There is nothing difficult
218 involved in using them; you just connect a TP chain to a hub on any end or
219 even at both. This way you can create almost any network configuration.
220 The maximum of 11 hubs between any two computers on the net applies here as
223 RP-------P--------P--------H-----P------P-----PR
225 RP-----H--------P--------H-----P------PR
233 Like any network, ARCnet has a limited cable length. These are the maximum
234 cable lengths between two active ends (an active end being an active hub or
237 RG-62 93 Ohm up to 650 m
238 RG-59/U 75 Ohm up to 457 m
239 RG-11/U 75 Ohm up to 533 m
240 IBM Type 1 150 Ohm up to 200 m
241 IBM Type 3 100 Ohm up to 100 m
243 The maximum length of all cables connected to a passive hub is limited to 65
244 meters for RG-62 cabling; less for others. You can see that using passive
245 hubs in a large network is a bad idea. The maximum length of a single "BUS
246 Trunk" is about 300 meters for RG-62. The maximum distance between the two
247 most distant points of the net is limited to 3000 meters. The maximum length
248 of a TP cable between two cards/hubs is 650 meters.
254 All ARCnet cards should have a total of four or five different settings:
256 - the I/O address: this is the "port" your ARCnet card is on. Probed
257 values in the Linux ARCnet driver are only from 0x200 through 0x3F0. (If
258 your card has additional ones, which is possible, please tell me.) This
259 should not be the same as any other device on your system. According to
260 a doc I got from Novell, MS Windows prefers values of 0x300 or more,
261 eating net connections on my system (at least) otherwise. My guess is
262 this may be because, if your card is at 0x2E0, probing for a serial port
263 at 0x2E8 will reset the card and probably mess things up royally.
264 - Avery's favourite: 0x300.
266 - the IRQ: on 8-bit cards, it might be 2 (9), 3, 4, 5, or 7.
267 on 16-bit cards, it might be 2 (9), 3, 4, 5, 7, or 10-15.
269 Make sure this is different from any other card on your system. Note
270 that IRQ2 is the same as IRQ9, as far as Linux is concerned. You can
271 "cat /proc/interrupts" for a somewhat complete list of which ones are in
272 use at any given time. Here is a list of common usages from Vojtech
273 Pavlik <vojtech@suse.cz>:
274 ("Not on bus" means there is no way for a card to generate this
276 IRQ 0 - Timer 0 (Not on bus)
277 IRQ 1 - Keyboard (Not on bus)
278 IRQ 2 - IRQ Controller 2 (Not on bus, nor does interrupt the CPU)
281 IRQ 5 - FREE (LPT2 if you have it; sometimes COM3; maybe PLIP)
282 IRQ 6 - Floppy disk controller
283 IRQ 7 - FREE (LPT1 if you don't use the polling driver; PLIP)
284 IRQ 8 - Realtime Clock Interrupt (Not on bus)
285 IRQ 9 - FREE (VGA vertical sync interrupt if enabled)
289 IRQ 13 - Numeric Coprocessor (Not on bus)
290 IRQ 14 - Fixed Disk Controller
291 IRQ 15 - FREE (Fixed Disk Controller 2 if you have it)
293 Note: IRQ 9 is used on some video cards for the "vertical retrace"
294 interrupt. This interrupt would have been handy for things like
295 video games, as it occurs exactly once per screen refresh, but
296 unfortunately IBM cancelled this feature starting with the original
297 VGA and thus many VGA/SVGA cards do not support it. For this
298 reason, no modern software uses this interrupt and it can almost
299 always be safely disabled, if your video card supports it at all.
301 If your card for some reason CANNOT disable this IRQ (usually there
302 is a jumper), one solution would be to clip the printed circuit
303 contact on the board: it's the fourth contact from the left on the
304 back side. I take no responsibility if you try this.
306 - Avery's favourite: IRQ2 (actually IRQ9). Watch that VGA, though.
308 - the memory address: Unlike most cards, ARCnets use "shared memory" for
309 copying buffers around. Make SURE it doesn't conflict with any other
310 used memory in your system!
311 A0000 - VGA graphics memory (ok if you don't have VGA)
312 B0000 - Monochrome text mode
313 C0000 \ One of these is your VGA BIOS - usually C0000.
317 Anything less than 0xA0000 is, well, a BAD idea since it isn't above
319 - Avery's favourite: 0xD0000
321 - the station address: Every ARCnet card has its own "unique" network
322 address from 0 to 255. Unlike Ethernet, you can set this address
323 yourself with a jumper or switch (or on some cards, with special
324 software). Since it's only 8 bits, you can only have 254 ARCnet cards
325 on a network. DON'T use 0 or 255, since these are reserved (although
326 neat stuff will probably happen if you DO use them). By the way, if you
327 haven't already guessed, don't set this the same as any other ARCnet on
329 - Avery's favourite: 3 and 4. Not that it matters.
331 - There may be ETS1 and ETS2 settings. These may or may not make a
332 difference on your card (many manuals call them "reserved"), but are
333 used to change the delays used when powering up a computer on the
334 network. This is only necessary when wiring VERY long range ARCnet
335 networks, on the order of 4km or so; in any case, the only real
336 requirement here is that all cards on the network with ETS1 and ETS2
337 jumpers have them in the same position. Chris Hindy <chrish@io.org>

363 The following is all the specific information people have sent me about
364 their own particular ARCnet cards. It is officially a mess, and contains
365 huge amounts of duplicated information. I have no time to fix it. If you
366 want to, PLEASE DO! Just send me a 'diff -u' of all your changes.
368 The model # is listed right above specifics for that card, so you should be
369 able to use your text viewer's "search" function to find the entry you want.
370 If you don't KNOW what kind of card you have, try looking through the
371 various diagrams to see if you can tell.
373 If your model isn't listed and/or has different settings, PLEASE PLEASE
374 tell me. I had to figure mine out without the manual, and it WASN'T FUN!
376 Even if your ARCnet model isn't listed, but has the same jumpers as another
377 model that is, please e-mail me to say so.

425 About the jumpers: On my PC130 there is one more jumper, located near the
426 cable-connector and it's for changing to star or bus topology;
427 closed: star - open: bus
428 On the PC500 are some more jumper-pins, one block labeled with RX,PDN,TXI
429 and another with ALE,LA17,LA18,LA19 these are undocumented..

690 The default is jumper ROM not installed.
693 Setting the Timeouts and Interrupt
694 ----------------------------------
696 The jumpers labeled EXT1 and EXT2 are used to determine the timeout
697 parameters. These two jumpers are normally left open.
699 To select a hardware interrupt level set one (only one!) of the jumpers
700 IRQ2, IRQ3, IRQ4, IRQ5, IRQ7. The Manufacturer's default is IRQ2.
703 Configuring the PC130E for Star or Bus Topology
704 -----------------------------------------------
706 The single jumper labeled STAR is used to configure the PC130E board for
707 star or bus topology.
708 When the jumper is installed, the board may be used in a star network, when
709 it is removed, the board can be used in a bus topology.
715 Two diagnostic LEDs are visible on the rear bracket of the board.
716 The green LED monitors the network activity: the red one shows the

736 =====================================================================
738 Note: There is another Version of the PC500 called Short Version, which
739 is different in hard- and software! The most important differences
741 - The long board has no Shared memory.
742 - On the long board the selection of the interrupt is done by binary
743 coded switch, on the short board directly by jumper.
745 [Avery's note: pay special attention to that: the long board HAS NO SHARED
746 MEMORY. This means the current Linux-ARCnet driver can't use these cards.
747 I have obtained a PC500Longboard and will be doing some experiments on it in
748 the future, but don't hold your breath. Thanks again to Juergen Seifert for
749 his advice about this!]

901 Setting the Interrupt
902 ---------------------
904 Switches seven through ten of switch group SW1 are used to select the
905 interrupt level. The interrupt level is binary coded, so selections
906 from 0 to 15 would be possible, but only the following eight values will
907 be supported: 3, 4, 5, 7, 9, 10, 11, 12.
916 1 0 0 1 | 9 (=2) (default)
925 The two jumpers JP2 (1-4) are used to determine the timeout parameters.
926 These two jumpers are normally left open.
927 Refer to the COM9026 Data Sheet for alternate configurations.
930 Configuring the PC500 for Star or Bus Topology
931 ----------------------------------------------
933 The single jumper labeled JP6 is used to configure the PC500 board for
934 star or bus topology.
935 When the jumper is installed, the board may be used in a star network, when
936 it is removed, the board can be used in a bus topology.

961 Note: this data is gathered by experimenting and looking at info of other
962 cards. However, I'm sure I got 99% of the settings right.
964 The SMC710 card resembles the PC270 card, but is much more basic (i.e. no
965 LEDs, RJ11 jacks, etc.) and 8 bit. Here's a little drawing:
967 _______________________________________

986 The row of jumpers at JP1 actually consists of 8 jumpers, (sometimes
987 labelled) the same as on the PC270, from top to bottom: EXT2, EXT1, ROM,
988 IRQ7, IRQ5, IRQ4, IRQ3, IRQ2 (gee, wonder what they would do? :-) )
990 S1 and S2 perform the same function as on the PC270, only their numbers
991 are swapped (S1 is the nodeaddress, S2 sets IO- and RAM-address).
993 I know it works when connected to a PC110 type ARCnet board.

1000 ---------------------------------
1001 - from Mathias Katzer <mkatzer@HRZ.Uni-Bielefeld.DE>
1002 - Marek Michalkiewicz <marekm@i17linuxb.ists.pwr.wroc.pl> says the
1003 LCS-8830 is slightly different from LCS-8830-T. These are 8 bit, BUS
1004 only (the JP0 jumper is hardwired), and BNC only.
1006 This is a LCS-8830-T made by SMC, I think ('SMC' only appears on one PLCC,
1007 nowhere else, not even on the few Xeroxed sheets from the manual).

1112 --------------------
1113 - from Mark Rejhon <mdrejhon@magi.com> (slight modifications by Avery)
1114 - Avery's note: I think PDI508 cards (but definitely NOT PDI508Plus cards)
1115 are mostly the same as this. PDI508Plus cards appear to be mainly
1116 software-configured.
1119 There is a jumper array at the bottom of the card, near the edge
1120 connector. This array is labelled J1. They control the IRQs and
1121 something else. Put only one jumper on the IRQ pins.
1123 ETS1, ETS2 are for timing on very long distance networks. See the
1124 more general information near the top of this file.
1126 There is a J2 jumper on two pins. A jumper should be put on them,
1127 since it was already there when I got the card. I don't know what
1128 this jumper is for though.
1130 There is a two-jumper array for J3. I don't know what it is for,
1131 but there were already two jumpers on it when I got the card. It's
1132 a six pin grid in a two-by-three fashion. The jumpers were
1133 configured as follows:
1137 :-------: ------> Accessible end of card with connectors
1138 o | o o | in this direction ------->
1141 Carl de Billy <CARL@carainfo.com> explains J3 and J4:
1147 :-------: TWIST Technology
1152 :-------: COAX Technology
1156 - If using coax cable in a bus topology the J4 jumper must be removed;
1157 place it on one pin.
1159 - If using bus topology with twisted pair wiring move the J3
1160 jumpers so they connect the middle pin and the pins closest to the RJ11
1161 Connectors. Also the J4 jumper must be removed; place it on one pin of
1162 J4 jumper for storage.
1164 - If using star topology with twisted pair wiring move the J3
1165 jumpers so they connect the middle pin and the pins closest to the RJ11
1171 The DIP switches accessible on the accessible end of the card while
1172 it is installed, is used to set the ARCnet address. There are 8
1173 switches. Use an address from 1 to 254.
1176 12345678 ARCnet address
1177 -----------------------------------------
1178 00000000 FF (Don't use this!)
1184 11111111 0 (Don't use this!)
1186 There is another array of eight DIP switches at the top of the
1187 card. There are five labelled MS0-MS4 which seem to control the
1188 memory address, and another three labelled IO0-IO2 which seem to
1189 control the base I/O address of the card.
1191 This was difficult to test by trial and error, and the I/O addresses
1192 are in a weird order. This was tested by setting the DIP switches,
1193 rebooting the computer, and attempting to load ARCETHER at various
1194 addresses (mostly between 0x200 and 0x400). The address that caused
1195 the red transmit LED to blink, is the one that I thought works.
1197 Also, the address 0x3D0 seem to have a special meaning, since the
1198 ARCETHER packet driver loaded fine, but without the red LED
1199 blinking. I don't know what 0x3D0 is for though. I recommend using
1200 an address of 0x300 since Windows may not like addresses below
1205 -------------------------------
1215 The memory switches set a reserved address space of 0x1000 bytes
1216 (0x100 segment units, or 4k). For example if I set an address of
1217 0xD000, it will use up addresses 0xD000 to 0xD100.
1219 The memory switches were tested by booting using QEMM386 stealth,
1220 and using LOADHI to see what address automatically became excluded
1221 from the upper memory regions, and then attempting to load ARCETHER
1222 using these addresses.
1224 I recommend using an ARCnet memory address of 0xD000, and putting
1225 the EMS page frame at 0xC000 while using QEMM stealth mode. That
1226 way, you get contiguous high memory from 0xD100 almost all the way
1227 the end of the megabyte.
1229 Memory Switch 0 (MS0) didn't seem to work properly when set to OFF
1230 on my card. It could be malfunctioning on my card. Experiment with
1231 it ON first, and if it doesn't work, set it to OFF. (It may be a
1232 modifier for the 0x200 bit?)
1235 43210 Memory address
1236 --------------------------------
1237 00001 0xE100 (guessed - was not detected by QEMM)
1238 00011 0xE000 (guessed - was not detected by QEMM)
1249 11001 0xC900 (guessed - crashes tested system)
1250 11011 0xC800 (guessed - crashes tested system)
1251 11101 0xC500 (guessed - crashes tested system)

1397 The memory buffer (RAM) requires 2K. The base of this buffer can be
1398 located in any of eight positions. The address of the Boot Prom is
1399 memory base + 8K or memory base + 0x2000.

1411 ON ON ON OFF OFF | DC000 | DE000
1412 ON ON OFF OFF OFF | E0000 | E2000
1414 *) To enable the Boot ROM install the jumper JP1
1416 Note: Since the switches 1 and 2 are always set to ON it may be possible
1417 that they can be used to add an offset of 2K, 4K or 6K to the base
1418 address, but this feature is not documented in the manual and I
1419 haven't tested it yet.

1619 Note: Other MEM-Base addresses seem to be selectable, but only the above
1620 combinations are documented.
1623 Setting the Interrupt Line
1624 --------------------------
1626 To select a hardware interrupt level install one (only one!) of the jumpers
1627 JP3 through JP13 using the following table:
1630 -------|-----------------
1641 13 | 2 (=9) Default!
1643 Note: - Do not use JP11=IRQ6, it may conflict with your Floppy Disk
1645 - Use JP3=IRQ14 only, if you don't have an IDE-, MFM-, or RLL-
1646 Hard Disk, it may conflict with their controllers
1649 Setting the Timeout Parameters
1650 ------------------------------
1652 The jumpers labeled JP1 and JP2 are used to determine the timeout
1653 parameters. These two jumpers are normally left open.

1813 Switch 1 (ID0) serves as the least significant bit (LSB).
1815 Setting one of the switches to OFF means "1", ON means "0".
1817 The node ID is the sum of the values of all switches set to "1"
1831 Don't set this to 0 or 255; these values are reserved.
1834 Setting the I/O Base Address
1835 ----------------------------
1837 The switches 1 to 6 of switch block SW1 are used to select one
1838 of 32 possible I/O Base addresses using the following tables
1850 The I/O address is sum of all switches set to "1". Remember that
1851 the I/O address space bellow 0x200 is RESERVED for mainboard, so
1852 switch 1 should be ALWAYS SET TO OFF.
1855 Setting the Base Memory (RAM) buffer Address
1856 --------------------------------------------
1858 The memory buffer (RAM) requires 2K. The base of this buffer can be
1859 located in any of sixteen positions. However, the addresses below
1860 A0000 are likely to cause system hang because there's main RAM.
1862 Jumpers 7-10 of switch block SW1 select the Memory Base address.

2228 "0" in the above example means switch is off "1" means that it is on.
2241 ENHANCED----------- 1
2242 COMPATIBLE--------- 0
2253 There is a DIP-switch with 8 switches, used to set the shared memory address
2254 to be used. The first 6 switches set the address, the 7th doesn't have any
2255 function, and the 8th switch is used to select "compatible" or "enhanced".
2256 When I got my two cards, one of them had this switch set to "enhanced". That
2257 card didn't work at all, it wasn't even recognized by the driver. The other
2258 card had this switch set to "compatible" and it behaved absolutely normally. I
2259 guess that the switch on one of the cards, must have been changed accidentally
2260 when the card was taken out of its former host. The question remains
2261 unanswered, what is the purpose of the "enhanced" position?
2263 [Avery's note: "enhanced" probably either disables shared memory (use IO
2264 ports instead) or disables IO ports (use memory addresses instead). This
2265 varies by the type of card involved. I fail to see how either of these
2266 enhance anything. Send me more detailed information about this mode, or
2267 just use "compatible" mode instead.]

2277 [Avery's note: these don't work with my driver for some reason. These cards
2278 SEEM to have settings similar to the PDI508Plus, which is
2279 software-configured and doesn't work with my driver either. The "Waterloo
2280 chip" is a boot PROM, probably designed specifically for the University of
2281 Waterloo. If you have any further information about this card, please
2284 The probe has not been able to detect the card on any of the J2 settings,
2285 and I tried them again with the "Waterloo" chip removed.

2439 Each node attached to the network must have an unique node ID which
2440 must be different from 0.
2441 Switch 8 serves as the least significant bit (LSB).
2443 The node ID is the sum of the values of all switches set to "1"

2487 ON OFF ON | 2E0 (Manufacturer's default)
2495 Setting the Base Memory (RAM) buffer Address
2496 --------------------------------------------
2498 The memory buffer requires 2K of a 16K block of RAM. The base of this
2499 16K block can be located in any of eight positions.
2500 Switches 4-6 of switch group SW2 select the Base of the 16K block.
2501 Within that 16K address space, the buffer may be assigned any one of four
2502 positions, determined by the offset, switches 7 and 8 of group SW2.

2967 up (on) SW1...(switches 1-5)
2968 IRQ3, IRQ4, IRQ5, IRQ7, IRQ2. The Manufacturer's default is IRQ2.
2970 The switches on SW1 labeled EXT1 (switch 6) and EXT2 (switch 7)
2971 are used to determine the timeout parameters. These two dip switches
2972 are normally left off (down).
2974 To enable the 8K Boot PROM position SW1 switch 8 on (UP) labeled ROM.
2975 The default is jumper ROM not installed.
