Hi, my first post.
I picked up this apple IIe (looks like a PAL version) in a garage sale, but it won't boot.
It won't beep. The drive won't respond. There is a light on the motherboard that goes on... but the video display is all blocky garbage.
I cleaned up the motherboard, and looked at some repair manuals that suggested investigating the CPU and one of the ROMS. I tested both and found them to be OK.
I actually borrowed a CPU from a Commodore 1541 disk drive (MOS 6502), no change.
Removed the EF ROM completely and no change there either. Tried to burn a replacement EEPROM of that chip and no change.
So now I am stumped. Can anyone help?
