A3000 wont boot

[Tension]

I've been sitting working with my A3000 all night.  It was working intermittently, but now, not at all.

I've removed & replaced the zorro cards, the riser, reseated chips & zips.

The keyboard light blinks once, as normal.

The screen flickers and the caps lock flashes once when i do a soft reset.

but the screen stays black, and the 2 floppys are silent.

Any ideas folks??

[Tension]

At least on my A4000's black screen means problem with the CPU slot.  Do you have any accelerator in that A3000?

I noticed there seems to be some damage on some of the pins on the 68030.

I installed my 3640 as per these instructions: http://homepages.ihug.co.nz/~miles.j/a3640.html

But it makes no difference. same symptoms.

If the pins on the 030 are damaged, does that mean that the 040 wont work either??

What a nightmare!!

Got it working!!

But havin g problems with checksum errors on newly installed SCSI hard drive.

Whats then best MaxTransfer / Mask setting for a hard drive on the A3000 internal SCSI port.

Havent had to change a MaxTransfer value in about 15 years
