Hi there,

I checked the ROM pins and the sockets, the contacts are fine. It is really one of the ROMs (can't remember which one right now) which is dead. I even tried to warm it up with a hairdryer, no change at all.

Is there any service document which shows the ROM pinouts? They seem to be mask programmed ROMs, no erasing window, no "standard" type. I tried googling the numbers, didn't find any information on these ICs. Ah, by the way, it's the logic board version with only two ROMs.

I wouldn't mind using a different type of ROM/EPROM/Flash memory with an adaptor socket in between, but I'd need the pinout to build one. Programming the new ROMs is no problem.

PowerPup: Thank you very much for your kind offer, but the problem is: I'm located in Germany, so shipping would be quite expensive, I guess. By the way, the screen looks exactly the same as my Classic II with dead ROMs. Did you check them? ;-)

Thanks a lot
