Left there and went to see the guy that I'd
meet that morning. He gave
me a ***MINT*** Visual 50 terminal, a MINT Sage II computer with ALL the
I haev a Sage II (the later model with half-height 80 cylinder drives),
and the _excellent_ owner's manual with full 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).
docs, a working HP 9845B, a stack of manuals for the
9845, a couple of HP
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!
