I'll look at prices when I get home.
It looks the same as when my 2 plus cpu was dead.

Assuming for a second that it goes and is an "enhanced", the 65C02, if gently levered out very gently (and evenly.) would provide at least a useful test. Actually even a 6502B would provide useful information. It'll fail to boot due to firmware problems, but it might answer the dead-cpu question.

I've ordered 5x 65C02 processors which should be here next week. I probably only need one or two, so if anyone needs one - sing out.

Hopefully I didn't just buy a box of duds! It will be very interesting - I'll let you all know of the outcome of that one.

Gibsaw wrote:Yeah, it'd be great to see what came out of that... and, if there was (ahem) a spare power supply around, I'd be willing to buy that too. (I had a blonde moment hastily demonstrating machines that culminated in a reasonably graphic illustration of the difference between 230v and a 110v. Surprisingly the machine got all the way to the DOS3.3 prompt before the power supply went bang. )
