TECH: PB-10 programmer question

[Guest]

Archived from groups: rec.games.video.arcade.collecting (More info?)

I know a lot of RGVAC'ers use this oldie-but-goodie eprom programmer for
their arcade games - I have an unused one still in the box that I bought
years ago (it is an ISA card, after all,) but just may have a need to now.

I've got a Galaga board that is giving me grief - everything works great
except all sounds except explosion. I'd like to dump the bi=polar sound
ROMS and compare them to the MAME dumps, but I can't find anything in the
PB-10 documentation that says it will work with these.

Does anyone know for a fact that a PB-10 will read (and/or write) these
bi-polar ROMS. If I understand correctly, the part numbers for these
ROM's are 82S123 and 82S129.

S.W.

You won't be able to write bipolars, but you can read them if you
wire up an adapter. Just map the pins to a 2716 and read it as such.

If all the other sounds are ok then the bi-polar proms are ok, the
explosion sound is generated in the 54xx chip at location 6M on the cpu
board and fed to the output amp in parallel with the other sounds.
