Default Re: Sun Microcomputer II Motortester 1215

Finally got a spare half hour this evening and got the back cover off.

It's surprisingly clean inside to be honest and is free from obviously bodgery.

Found a sticker confirming that the production date is Aug 1984 which is pretty much bang in the middle of the period I'd guessed.

The issue with the display dropping out seems to be influenced by wiggling the "CRT" card in the cage, so hopefully just a dirty contact or dry joint in that area. Will let you know how it goes when I get time to strip it down a bit further (have to remove the faceplate to get the cards out fully sadly).

Watch this space.
