Strange... I always look at the schematics first, if they're available
(then source listings, and finally any user-manaul type of info...).
To each his own! I haven't had time to read ANY of the manuals yet. I've
only looked at the covers.
What's a Pluto graphics unit? The Sage only comes with512k of memory
The Pluto was a reasonable hi-res (for the time) graphics display system
with its own 8088 microprocessor. Jules Richarson found one a few weeks
back iIRC. I hvve one somewhere, it came with a Sharp MZ80-B, not with
the Sage, but I think it's the same unit.
I wonder who finally ended up with his archive? Several people tried to
take it over.
Oh for %deity's sake... There are 2 threads about this at the moment on
classiccmp. Do you actually _read_ the list ? :-)
I can't read the future and that tread was started AFTER I posted the
question.

Which means I'd better dig out my Sage again. I think I know where I put it.

Sage II (the later model with half-height 80 cylinder drives),
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
The schematics in the back of my Owner's Manual only show DS0 and DS1
wired up, so I guess it only handles 2 floppies. Winchester drives. IF you have the Winchester
board. I don't :-( It
Nor do I. But to tie in to a thread a few weeks back, I have a
third-party board in mine. It's fixed on pillars stuck to the main board,
and connects to the 2 50 pin bus headers. It contains a few TTL chips,
and has a 20 pin header that's designed to link to a Pluto graphics unit
(or at least that's what I think it's for). Alas I don't have any
software to drive it. (max). The Winchester adapter also contains up to
512k bytes of additional
RAM. Any ideas about how to built a RAM card that can be used to increase
the memory of the standard Sage?
Well, you have the system bus on those 2 50 pin headers. It should be
fairly easy to wire up some modern SRAM chips to those, with a bit of
address decoding logic.
CPM-68k for it so I'm on the look out for those.
I hate to mention this, but IIRC Don Maslin's archive contained CP/M 68k
for the Sage :-(
All (!) we have to do is find some way of transfering disk images to me
in a format that I can actually make use of.....
Snail Mail! I'll make copies as soon as I get it fired up. I need
backup copies anyway.
