it's just like a standard pc in that if you have a boot floppy, preferably dos
2.1, it should load. or, if a cart is in one of the two front slots, it should
load off of that. the disk drive in it is the same as the slim height floppy
drives the portable pc used.

If anyone needs a couple of memory boards for their MicroVAX, here's a
fellow offering a couple of 1 meggers dirt cheap.

I picked up an Apple Macintosh IIci today. It has a board in it marked
"Orange 386". It was made by Orange Micro has a 386 CPU and slots for SIMM
memory boards. Is anyone familar with this? I don't have an Apple
monitor so I can't power it up and test it.

I believe the DOS version was PC-DOS 2.11. From reading previous posts on
this list, and other places, the floppy drive in the PCjr was fairly
flimsy, so if may be a "standard" problem.

It is IBM's clone of the PC/AT with a few exceptions.
Hmm, I'm sure you don't mean "IBM's clone of the PC/AT", since IBM could
hardly clone their own product. The XT-286 is actually a warmed-over PC-XT
motherboard design, adapted to use the 80286 CPU. It was a product
positioned in between the XT and the AT in IBM's lineup.
3. Some AT boards will not fit into it.
Actually, no AT boards will fit into it. Although it used the AT's 286 CPU,
it retained the XT's 8-bit bus, and was limited to 640K RAM (no 16-bit RAM
expansion available). In a sense, you can almost think of it as a "286SX",
since it is largely analogous to the 386SX in that it had a bus half the
width of the CPU internal core (although I'm not sure whether the
motherboard RAM was 8- or 16-bit). The XT-286 failed, not just because of
its limited expansion versus the AT, but due to competition from the Turbo
XT (8-10MHz 8088/NECV20) market, which had similar performance.

I have an XT/286 in a box and used it for many years.
It is IBM's clone of the PC/AT with a few exceptions.
1. It uses an XT case
2 It is 6mhz with 0 (zero) wait states.
3. Some AT boards will not fit into it.
Due to the zero wait states it is faster than other 6mhz AT's that do
have wait states.

It's a PC compatibility card, similar to those Apple used to sell. Orange
Micro is still around, currently selling Pentium cards.

I know someone at Edinburgh who was trying to persuade a Catweasel
controller to read/write unusual formats, but last I heard he was making
heavy weather of it. Here's the Catweasel URL:

I have recently came into position of an old Xerox computer that I
really do not know much about and was wondering if anyone out there
would be able to send me via e-mail any info that they may have on it.
The computer works and all but all that comes up is something about
tables and something about invalid drives. If anyone out there has any
info on this computer I would greatly appreciate it.

You can look at http://members.tripod.com/~apd2/catweasl.htm for an ISA card
that'll (allegedly) read several MFM and GCR formats, including Commodore,
Amiga, FAT, Atari, Macintosh, and Apple //.
I haven't ever used one, so I can't comment on its reliability, but it might
be worth investigating.

Of course you have to realize that this is an NC (in the modern sense). A
VAXmate worked really well in a network environment with a VAX at the far
end running Pathworks. I remember setting one up in 1987 and being
impressed with what you could achieve. It was really nice being able to
store PC data on our VAX which we backed up properly!
Of course, like DECs other NC (the Multia) they were ahead of the market
and couldn't sell them to save themselves :-(
