So, I followed the directions at http://www.area536.com/projects/amiga/upgrade-amiga-500-kickstart-from-12-to-31/

Did so VERY carefully, counting pins several times to make sure I was on pin 31 and nothing happens.

All I get is a black screen.

ROM checks on in another machine, so I know that's not the problem.

Motherboard works with 1.3 and 2.05 (with the wire from 1 to 31).

Any suggestions?


No, sorry buddy. Can anyone here explain the checksum errors he was getting though from accessing his 1.2 disks on 3.1?

Is there anything besides the floppy drive connected to the motherboard?
