I've just replaced my logic board on my Apple IIGS with one which I got from ebay (action reported fully tested and working). ROM 01
I'm using a CFFA3000 and a hard disk system 6.01 image from http://www.whatisthe2gs.apple2.org.za
I get this when trying to load System 6.01: (see attachments)
I've run the Apple IIGs QRAM diag disk. All tests pass. I've run the Apple IIGS Diagnostics V3.0 disk too. All tests pass.
Am I missing something? Is something else faulty on the Logic Board that the diagnostics programs don't detect?
