Default Re: Sun Microcomputer II Motortester 1215

Oh joy...let's hope I get lucky on the tantalum lottery this time round...have played that game before.

Initial signs are good. Only had five minutes but after checking I had sane readings on the Megger I powered it up (it's been run up to demo to a prospective buyer recently). When doing that check showed the most recent PAT certificate on the mains lead dating from 2005. So it's not been out of use for that long compared to some stuff I've revived.

We do appear to have a video fault in that the computer display keeps dropping out, but it doesn't seem to be affecting the actual data on screen, so likely the video signal itself is intermittent...innthe grand scheme of things though I'll take that as a starting point.

Judging from how pin sharp the CRTs both are this hasn't done a massive number of hours...the photo actually makes it look far softer than it is in person.

Hopefully will get an hour or so to look at it after dinner tonight.
