Need some information. I picked up a Sprint 2 and I'm missing a prom from D1. What eprom would be compatible for this? Can't find any info.

If these are the same as breakout then I don't think there's anything common that's compatible. I could be wrong on this but I was researching a missing chip on break out a few months ago and as I recall it was nothing that I've ever seen before or anything common that's compatible. Probably the easiest solution is a CPU daughterboard to replace the roms. That said I could be wrong about the chip.
 
Yeah the 2k ROMs that games like Sprint and Super Bug used were pretty different from anything else I've seen. I have a Canyon Bomber that uses the same thing that I can't do anything with. Mark Spaeth has talked about making some sort of adapter/ multigame for it but as far as I know it isn't available.

That said looking at your board I think you may still be OK. It looks like those 4 smaller PROMs could be used in place of the larger 2k one. It was not uncommon to see this mix and match on boards from this time

There's another thread about this board where I IDed the ROM type and pinout.
 
You're not missing that PROM... it's just populated with 4 1kx4 proms for that location instead of 1 2kx8.

There is no drop in EPROM replacement, but I did make boards to do the trick...

Please let me know when the board will be available.

Sounds great. Would it work with other games too? I have a Canyon Bomber and Super Bug that could use this too
