Detailed PGM specs
« on: February 13, 2008, 09:34:11 PM »
Anyone know more details about Cave's PGM hardware specs? I know about the 68000 CPU @20mhz, and the sound chip. What about the graphics chip, RAM, etc? There are a lot of chips on the boards.

Did some google searches, but came up empty. :/

Yes, I found that info. I was wondering about the other stuff on the board (graphics chip, RAM, etc).

RAM amount is:

EliteMt LP61256GS-12 - 32Kx8 SRAM - 5 chips
Winbond W24258S - 32Kx8 SRAM - 4 chips

Anyone have a datasheet on the EliteMt ?
