Started prepping the Microdata for restoration tonight. The cpu, mag
tape, and front panel are in very good condition. The power supply -
not so much. It was apparently a long term home for mice. I don't see
any chewed wiring - suprising - but their leavings induced a lot of
corrosion and rust. I'm gonna bet those batteries aren't holding a
charge. No power applied yet, going to go through the power supply
with a fine tooth comb first.
I thought the box was an M1600 for some reason, but it appears to be
an R4510. Many years ago I did own two M1600's, and this box seems
extremely similar, but the front panel is more reminiscent of the
Reality Royale rather than the M1600.
I haven't located all the stuff that came in the haul, but enough to
get started in any case.
The power supply is Microdata A20014662-002. Dare I ask.... any
schematics?

It's been over 30 years since I had my hands inside the guts of a
Microdata Reality. Brings back lots of memories.
I've got the power supply pulled out and on a bench, all the cabinet
panels removed, and cpu cables marked & removed. Haven't dug the
Reflex I drive out of storage yet.
There's also a box of serial number proms :)
