Were the A3000 boards ever working with you or did you get these board from elsewhere and are now putting them together?
What KS Roms are you using? what version of WD SCSI controller? what version of chips have you got like buster, Dmac, etc?
N
ear the CIA have you got all the SCSI termination pins (I can't remember their proper name)?
I would remove that battery if it is the orginal even if it doesn't look like alot of damage.
i know i had a hell of a time with all the jumpers to get my A3000 working.
Are you using zip ram or is fast memory banks empty?
IF you have received these broads from elsewhere I am leaning towards some weird jumper setting.
