Hi All,
I've got an MVF-1A (from memory) which displayed garbled graphics on power-up and continually reset. Traced it to a bad DTACK to the 68K - pulled it active and my one-and-only game runs fine!
Any ideas on the cause? Anyone with schematics that can tell me what generates this signal? or give me a copy of the schematics???
TIA
Regards,
