Could someone with access to an ST-Key or Satellite cartridge please open it up, and if it contains a pair of 32-pin flash chips, tell me where pins 22, 24, and 31 are routed?
Yeah, 27C series is an EPROM. For a 40-pin EPROM, I'd be looking for pins 2 and 20 (which in all likelihood are run to the PAL). It's odd that there's a PAL on a single-memory cart. Does that cart have a comms port or anything else noteworthy?
That's just weird; the only reason I can think of to use a PAL in there would be if the SCU actually doesn't provide pre-decoded chip select and read/write signals...
