Colour Classic plus Performa 250

I've tried them both out - the CC works perfectly, but the 250's screen is green and blotchy and it won't boot. The screen should be fixed by leaving it plugged in overnight - apparently they have built-in de-gaussing circuitry, and the booting is easy to fix.
I'd forgotten just how slowly an LCII runs. 16 mhz of molasses. Yikes.

Very nice score. 
As for the slowness of an LCII, here's something - although its completely unsupported, any LC II will, straight out of the box, boot into, and run System 6.0.8. Not System 6.0.8L, but normal System 6.0.8. I'm curious if it would run on a CC also, or if they've changed the ROM too much....something to try, anyway.....
For the record, welcome back elbaroni

The degaussing circuitry is only activated for a few seconds at turn on. And once activated, you can't reactivate for some time (components need to cool off). So, if you have the need for serious degaussing, simply leaving it on overnight won't help. You'll need to cycle it on and off many times, with long waits in the off state.
In severe cases, it's best to use a separate demagnetizer (if that's the problem with your splotchy screen).
Thanks, Tomlee. I read somewhere (Pickle?) that leving it plugged in, turned on at the back but shut down was the way to fix the screen. I'll give that a go first (seeing as I can do that as I sleep) and try your method if that doesn't work.
I think 6.0.8 won't work on a CC. When I said LCII, by the way, I meant the CC, which is the same processor and crappy logic board. Roll on the 575 board, says I.

Also wulcum back. It is a most-often effective way of re-inducing the pseudo-softpower ('active power control' in Apple's parlance) to return to the job after some time off the mains power. Given that the second thing that you do after receipt of a CC/P250 (after opening and cleaning) is to check/replace the PRAM battery. Be not dismayed to find that the battery varies between 3.6V lithium and 4.5V alkaline depending on production date.
Nice catch, by the way. P250s are not easily come by, although Australia seems to have been one of their stamping grounds. You are perhaps a tad unkind though: what can reasonably be expected of a 16MHz machine throttled back from 12MB actual RAM to 10MB useable, and blessed with totally inadequate screen real estate? Cute, yes. Useful, once, when aspirations were lower.

This is a handy reference to have nailed to your 'frig. door. It will give you choices, and a means of distinguishing, between loose yoke, defective caps in the horizontal deflection circuitry, bad power-supply, and many others. I've not met such behaviour as you describe in any of my CCs/P250s (6), so I shall leave it to others (murmur the name of tomlee59 into a megaphone, and see whether he is listening) to chime in with their favourite faults. In the meantime, happy reading!
