I forgot to add: I first built the 6502 board and did the freerun test. Then I wrote an eprom with a small test program and checked that it was running by probing the address lines and confirming that the accesses was within the boundaries of F8/F9xx. After I was sure of this, I started trying to get output on video. -- You received this message because you are subscribed to the Google Groups "N8VEM-S100" group.
