The 3500 has the following:
9988 rev 3 memory card (no idea of it's size)
3com ethernet card
9016 (RGB video adaptor)
WD7000 scsi/hdd controller
The WD7000 is an ESDI controller
tape drive
unknown
Unfortunately I don't have the RGB cable or the monitor.
Questions:
* Can I use the mono display adaptor in the 3500? Can I run one
of these boxen without a display card, or do they check like
peecees?
* How ISA compatible is the ISA bus? Can I stick a VGA card in
there and expect it to work (OK, I know I'll have to write
the code (port the VGA BIOS) but I mean electrically? Or
an IDE controller?
The bus is completely incompatible with the PC ISA bus. Nothing is likely to
work.
* Where can I find memory maps, circuit diagrams,
whatever?
* How rare are these beasts? I gather they're common? Any
objections to me ripping out all the cards and the boot
rom, sticking vmebug in the socket, and an IDE drive in
the bay, and playing with the thing?
I have one I found complete in a dumpster. There were many color monitors
with it but I only took one because they are so huge. It didn't have a
monitor cable with it but I have one from a Decstation that works OK. They
run a unique OS called Domain which I don't have. Mine has a 300meg ESDI
drive and a tape drive. I've had mine up as far as looking for something to
boot from.
