Re: DX7s mainboard (DM) reborn attempt

Thanks. OK, I will try this weekend and see if I can get everything that's in the cartridge. Did yours contain a 27512 (64k x 8) or the larger 1M (128k x 8) mask rom? I noticed you saved it as a 64k file so we can assume that the other half is the mask rom is empty I guess. Curious. I looked at the PCB and it's the same one as here, just with different jumpersin place.
