outrun pcb missing chips
Xiaou2:
i believe that there are a few different sets of roms that need to be burned with the appopriate board.
ie: some boards are bootlegs, and need the bootlegs roms burned for them - else they do not work correctly.
I also need my outrun roms burned... however... i cant seem to understand which romset i need for my boards.
Any outrun experts willing to help?

For example:
IC34 OPR10209
I need to know the actual memory chip type. E.g. 32 pin 27C1001 (1Mbit) with 150ns speed or faster EPROM. Also, some ROMs/EProms have different pinout. So the pinout needs to match as well (or otherwise, get ready to lift pins and run new wires!)

The chips are 28 pin. Pins are 3mm apart. The top reads:
SEGA
MPR-10377
831000-20
337 BK
8710 Z82
The under side says H2 in 1 circle, 1 blank circle.
I did a search for the chip # and I found one made bt Fujitsu 831000-20.
I could not find anything on the speed of the chip or any pinout info. If you know of a place to find it let me know and I will look it up.
