I am currently in the process of converting a Tapper boardset over to a Discs of Tron boardset.
I downloaded some ROMs for DOT, and the labeling of the ROMs that go on the video board is a bit strange.
The downloaded ROM images are labelled a through h, with suffixes that read 'cp3' through 'cp9' and then one that is 'cp0'. The board has sockets for ROMs in locations A1 through A8. There are also small capacitors next to each ROM socket numbered 'cp3' through 'cp10'. My guess was whoever first dumped these ROMs to MAME just used the capacitor labels as ROM labels, and left off the '1' from cp10. This would put the contents of the cp0 file in the ROM socket next to the cp10 cap.
..but that's just a guess. The schematics use a different numbering scheme than any of these others above, so no dice there. Can anyone confirm the proper locations of these ROMs?
Thanks!
