I intend to convert a Model 2 PCB into Indy 500
Can anyone confirm for me the type of 40-pin EPROM that goes in the 42-pin sockets?
The MAME information says that the 512kb eproms are all 27c4002 or 27c4096.
but in my experience the 512kb eproms that go in 42-pin sockets are the 27c400.
But perhaps SEGA made it possible to use 27c4096 in 42-pin sockets through the jumper setup.
Could anyone confirm for me the model of the eproms?
