Data East DMD controller board.
520-5055-00 REV. D 1992
Clean looking board but tested and sadly not working
3 socketed chips which all tested good in my other board, so not those that’s the issue.
Anyway, someone might be able to fix or use for repair, spares.
Ground jumper across the back from the Pal chip, not sure why, no burnt traces.
ROM chips NOT included
