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?

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 :) Pictures are at www.ezwind.net/microdata Game on :) J
