Friend came down for visit with an A3000 in hand. Problematic booting, if any. Unit has taken a surge/spike.
Floppy drive would spin, then stop. Manual spin of flywheel would re-start. Disassembled drive, used cleaner solvent to remove " TOBACCO FILM " from flywheel and hub bearing. Floppy drive now works.
Hard drives: A2091 and motherboard both had boot drives attached. The A2091 was disabled (jumper) as needed to perform these tests.
NO BOOT, either drive: replaced the 3.1 ROMS
The unit will -now- boot with an A2091 SCSI card, but not from the motherboard SCSI controller.
The following chips were swapped out, one at a time,, then the test was made again.
Buster11, DMAC 2, SCSI WD, Paula.
Any ideas?
