I did see that but that is slower, mine are -10 those on ebay are -12. Now here is the funny part in the Race drivin book it states "Integrated Circuit, VRAM, 64Kx4, 150 nsec(Acceptable substitute is part no, 137553-001, Integrated Circuit, VRAM, 64kx4 120 nsec) " So my guess the -10 are 100...

I have a picture attached. I am having trouble finding it. If anyone know where I can pick these up let me know. Thanks, Chris

OK Just some info for all, the chips read just like the numbering on the board. I touched the chip and it was really hot. The chips are 42C4064-10.

OK I got my dream machine. Once the game boots up it unpacks gsp... and then reboots. I put it in test mode and the system states BAD GSP VRAM. I test the GSP and at the end it shows 16 boxes the 1st one is red and the rest are green shown below. How can I found out where the red chip is...
