Classic II Reset

I have a Classic II that worked great before I moved. After the move, I left it in a dry garage for about 4 months. I went to boot it up yesterday, and there is a checked board like screen - but I do not see any type of boot sequence. No Happy Mac face, no unhappy Mac face.

I am guessing that the best thing to do is reset it. There is some sort of reset button on the side, but nothing changes no longer how long I hold it in. Any suggestions?

Thanks in advance!

The last time I saw a checker

The last time I saw a checkerboard pattern on a Classic screen was when the PRAM battery inside leaked and corroded the motherboard.

dirty ram slots


cleaning ram chips, rom simms and any pds device is the first response to a checkerboard pattern. You might want to check for leaking caps but that won't cause a checkerboard pattern, per se. Be a good idea while you're in there to change the battery. How many times do you want to go in?

These comments pretty well ha

These comments pretty well have it covered, but this is a great site for this kind of problem so I thought I would post a like anyway. Lots of other interesting info there.

I found it by googling because I had the same problem with a Classic II I got at Goodwill. Haven't got around to seeing if the suggested fixes work yet.

The Shamda site is for the SE

The Shamda site is for the SE/30. The idea may be the same for the fix, but I wouldn't take it word-for-word on what to do on a Classic II.

Not uncommon.

In response to Dr. Check:
Haha! I just got my Mac Classic today. Same thing happened. Dunno if you'll read this comment, seeing as you posted that nearly two years ago, but I thought I'd mention it and bring an old thread back to life for no good reason. Tongue

Now I need to grab a Classic II board off of eBay.
