IIRC the PS/2 had a 5.25" drive option in certain form factors.

I am trying to get a DECstation 220 working again. It looks like the 80286
is being constantly reset. The reset signal seems to come from an Olivetti
GA099-B chip. I have not been able to find a datasheet for this online. Does
anyone have one, or know where I might find one?
Thanks
Rob
So, Paul A lent me a set of these (thanks Paul!) so I could scan them in (they
are not currently available online).
Howwever, there's a problem. The last page in the set contains the circuit
diagram for the M7248 BBSY Repeater card (the heart of the whole device, since
the DB11-A uses BBSY to deci

i'll try to get to it today
They screwed up when they made the maint prints, it's missing from ours as well
I will see if it showed up in the individual module schematic collections,
though
that will be much more difficult to go through. I scanned binders full of them,
but
they aren't sorted.

There was also the MCA Diskette Adapter/A, which didn't work with much
"low level" software.

Yes. External 5.25" drives, both 360K and 1.2M were available for the
PS/2 line. It was just a matter of power and signal cabling to put
together your own.
There was a bracket with a DC-37. That could be used for PC external

As I mentioned in an earlier email, I have been trying to fix a DECstation
220. I have made what I think may be some progress, but I am out of ideas
now.
The problem appears to be that the 80286 CPU is shutting down and then the
Olivetti chip is RESETting it repeatedly. The reason for this seem
