What OS are you running on each of them? I'm thinking that
this could make an interesting portable LINUX workstation and it
would appear that most of the MCA hardware such as SCSI and NIC cards
are supported under it.

My P70 runs OS/2 (as it should) and the P75 runs win95 suprisingly well in
16meg. Since P75 runs scsi, it would benefit from a more modern and faster
SCSI drive. Unfortunately for the P70, that drive is ESDI or that modified
IDE that the mod 50s and 70s used.

Its to plug in an external floppy drive such as the 4869. I found the cable
for it on ebay. The P75 looks the same, but a bit thicker and has SCSI. I

Some flavour of Cayman GatorBox, perhaps? I have a GatorBox CS (you can
still get software updates from Cayman's FTP site), and although I've never
tried this, it is supposed to be able to allow Unix machines (or other
machines that talk TCP/IP) to print to Laserwriters on the Localtalk bus.
We used to have two at work which allowed Mac users to use our Unix
printers and Unix/NFS filestore (which suggests it does translate properly
in both directions). They also allowed our Macs to talk to others on the
campus, which involved going through at least two IP routers and the ATM
network as well as the two ethernet segments and GatorBoxes, though I think
that used some sort of tunnelling mechanism. And of course all the Macs,
PCs, and Unix machiners could ping and telnet to each other, though I'm not
sure how much of that involved the GatorBoxes and how much was done by
software in the Macs.
We no longer have/use the GatorBoxes at work, though two other Departments
still do, I believe. Our Mac users use Dave to talk to the print servers
and file servers. I don't know much about it, but I think it's a sort of
Samba client -- doubtless some of the Mac users on the list know much more
than I.

Rewire. The reason most of these devices use three phase is to
distribute a load more uniformly over what was a normal power system
in computer rooms then. Also many of these devices have a rather harsh
startup current and slicing it two or three ways makes it much easier
for the sytem (wiring and power circuits) to sustain.
For example a lowly MVII in a BA23 has a startup surge of over 100A
for one cycle (about 16mS). In the second 16mS that might be only 12A
and by the 10th your near nominal of say 3.2A. If you turned ten of
them
on at the same time and same circuit the running current is maybe
32-40A but the starting current could easily exceed 1000A for several
cycles. Why? If they were all on one breaker the whole load would
attempt to bring the caps in the power supply up that first 16mS...
save for the 10,000A surge would pull the 115v down to say 60V
(assuming thick wires and the fuses held!) the next cycle would be
needed to charge those caps more, likely 10 or 15 cycles so the huge
current would take longer to dissapate. Add motors like the RP06 with
their nasty starting currents and you see why power systems were so
robust. Granted the startup condition is pathological as no one would
do that (staggered is also common) but the need to distribute the
sustained load is also important.
If I had a 6000, I'd ahve rewired it already and could tell. Most often
(but not always) three phase power is used as independant legs.
Exceptions would be beasties like VAX9000, PDP10s and other
power hungry older machines.

Sean, there are several ways to talk to a GatorBox CS (telnet, SNMP, direct
serial connection). They all have limitations, and it's a long time since
I used any of them, but if you want to contact me off-list, maybe we can
compare notes and get something going. I've got all the manuals, and a CS
to talk to, though not a Mac to run the software on at the moment.

I've had great luck with Netatalk (except for having to reboot the Linux
box all the time when making network changes). When it's running, it
runs well.
I happen to have this ancient Appletalk card - DB9 connector and all. I
remember researching it a couple of years ago and there was some interest
in Linux drivers. Never did hear what happened to it.

I found it with an Altavista search on OMTI and 3100. I don't mind
looking - I have two of them myself up on a shelf.
Enjoy,

Would this just be something like a 68882 on a small card?
