Anyone know where to get the Exidy custom video chips? I'm looking for 12h. They are bipolar proms. I see many places sell the chips, but where to get them programmed? I don't have a bipolar prom programmer.
I actually wasn't aware that the Exidy 440 boards had a security chip. Though, if there is it's not the one need. I need chip 12H which is part of the video sync circuit. If there is a security chip, it's probably the 6331 @ 3K. Haven't run into any problems interchanging it with other boards/games.
I don't think it's game specific as everything is based off Crossbow. So, I guess it would be for Crossbow. I need chip 12H labeled XBL-12H. Christmas is coming and I'm packing hobby things away to make room right now. As soon as the holidays are over and things settle down, mid January, I'll hit you up for a burned chip. If you don't already have the file, I believe I have the file from MAME. I can try to verify the code before I contact you. I can read the code from another chip using my burner, but it reads it as 8-bit data and every other 4 bits are 0's. Thank you.
