As said above already: remove and reseat the CPU card,  and clean the contacts. I had the same trouble with my old (and now your) A4000, and after reseating the CPU card twice and with a slight bit of pressure it booted up.

I think the problem might be in the CPU connector on the mainboard - if (one of) the pins in there are slightly bent back then it doesn't boot up. Examine those pins and when needed, gently bend them back with a small pointy thing (like a needle).

Really, your A4000 is in working order, she just needs some TLC.

Yes but this machine wont boot up, even without the card inserted so it can't be that.


Well, that's pretty logical: there's no computer in the world that boots without a CPU :-)

Do I see an 030? I don't quite catch you on that.


The A4000 rev.D had an onboard 68030. Yours is a rev.B, so yours doesn't.

But I will have another good look at the 040 board, would you know who I can send it to to get repaird if needed?


Don't rush things before you are absolutely sure. I sent you the A4000 after I tested it and it WORKS. Just be a bit patient, clean the contacts of the CPU card, reseat it, press it down gently (you can even try pressing it down while powering up the machine - I did that as well, just don't touch any metal parts and make sure you are properly grounded). I'm 100% sure this machine works, it's just some quirky contacts with the CPU card.

UPDATE: I have the pink screen of death. 7 "256" items have been listed as defective.


Try booting with only the CHIP ram SIMM installed?
