Dead A4000/040

[chiark]

The 4000 *will* boot without the expansion riser card.

for what it's worth, my 4000/Warpengine 4040 recently died and it turned out to be that the warpengine had died.  Damn.

Hope you get it working again - I'd suggest trying another known good 3640 or 3630: someone was kind enough to sell me a 3640 for $50

Good luck - the guy I bought off was also selling an Apollo 4040 and if I'd have known the warpengine was dead, I'd have had that instead...  

Try a "wanted" advert, and point out that you've got a dead machine that you're working on - you might get lucky?

EDIT: if I find anyone with a working CPU card for sale, I'll drop you a PM.
