Microbee Disk System power supplies question

[RedskullDC]

Another question: One of my 3 PSUs is a bit unhappy. I have a MeanWell PSU with +5v and +12v on hand. Does anyone here know what the various rails were rated for on the original? I might be able to do a PSU Swap if it's not too high.
Googling "Microbee Disk System PSU" really doesn't find many helpful links :-)

Cheers!

Hi John,

Power Supply is an ASTEC AA12100, as found in many units of the early 80's vintage.

Osborne #1 service manual actually has a schematic on page#265:
http://www.bitsavers.org/pdf/osborne/2F0...n_1983.pdf

Ratings (on page #264) are:
5V @ 2A
12V @ 1A
-12@0.1A

Be careful if you are making up your own drive power cables that you don't short -12V to GND.

Cheers,
Leslie
