Subject: Re: Very Serious Mac Classic Problem...
The one bad 68000 I came across was in a first-gen SE. It was
constantly bombing like your Classic. A quick run through with Snooper
revealed a bad 68000. I know of no way to fix the problem aside from a
complete motherboard swap.
Come on! Where's your ambition? I haven't checked lately, but many
years ago, the 68000 CPU was a $10 part at Radio Shack. I know a
local store (non-RS) that has a couple on hand. I don't know what
they get for them though.
Snip the 64 pins on the bad CPU. Desolder the pins one at a time.
Clean the holes. Insert new CPU and solder into place.
Tedious, but not really challenging.
Oh. But does the Classic use a DIP or a PLCC? If a PLCC, it's a
little more difficult to snip the pins on the old CPU, but a little
easier to desolder the pins and clean the pads afterwards. Digi-Key
lists the PLCC 68000 for $12.28 each or $9.37 each if you purchase 25
or more. :-)
