So I finally got my eprom burner tonight and spent time verifying roms for my Blasteroids. Currently the board is 99% dead and has been for most of the time. Initially it gave a rom error so I thought I'd verify the rom in question (4C I believe) when my burner arrived. I ended up finding 4 that read as really messed up and was able to erase and re-program them. At first I wondered if I was not using the burner correctly but a large group of eproms on the other side of the board verified fine (comparing these to the MAME set). So like I said the board is still doing what it did before which is mostly nothing. If I put it into test mode and re-boot I can get a few screens of changing color like it should normally do but then that's it. Game mode gives nothing at all. Power as measured across a TTL chips is at 5 volts. At this point I'm guessing maybe processor or checking to see if the clock is even running? Anyone have any thoughts on this?
