That's like mine but it only has one HH drive. Any idea if these will
handle four floppy drives? The manual says that it could handle four
Winchester drives. IF you have the Winchester board. I don't :-( It
doesn't say about the floppy drives other than you could get two drives in it.
I know! I have a several of them and I've already worked on a couple of
them. One was easy, the huge inductor in the power supply had been knocked
loose and I just had to solder it back on.

schematics in the back. What
I don't have is an OS for it :-(. If anyone has the set of original disks
that came with such a machine, I am looking for copies (IIRC it was the
UCSD p-system, with some Sage-specific utilities).
You're in luck. I got all four original disks. I haven't looked closely
at the manuals yet but they look like they're pretty complete. I got five
manuals with it: Assembler/SDT, p-System Program Developement (I think this
compiles to native code and not just p-code), p-System Operating System,
Getting Started/Word 7 and Technical Manual. In one of them it mentioned
that there was also a Service manual and a Operating System Architecture
Manual. I have the Assembler for it and I'm pretty sure that it includes
the Pascal Compiler. They say that they also had Fortran and BASIC and
CPM-68k for it so I'm on the look out for those.

There's a 9845 in many bits on my bench at the moment. %deity it's a
complicated machine.... I think I just about understand the buses now
(and evne that's complicated -- there are 2 main buses, essentially
'language' ROMs and memory on one, 'peripheral' ROMs and memory on the
other (one ROM drawer is on each bus), both processors have access to
both buses, the video system can access both buses via the peripheral
processor's buffers, etc. Evne the PSU is about twice as complex as you'd
expect!
