So, i have been burning chips for the VS system, and had a fellow KLOVr Pm me about chips for their Super System cart.
So i have the information on the 3 chips on his cart:
(NSS-R IC2) PRG ROM-1
TOSHIBA
TC574000D-150
JAPAN 9150EAK
VPP 12.5V
(NSS-R IC3) PRG ROM-0
TOSHIBA
TC574000D-150
JAPAN 9143EAK
VPP 12.5V
Markings for the single 28-pin rom (NSS-R IC8) INST ROM:
TMS (Texas Instruments logo)
27C256JL
LDE 8901
So, my question is... The rom contains 2 512k files for the program. When i looked up that chip i think it came up as a 4meg chip. That can't be right?! Can it?

The chips are 4 meg chips, and a 512 chip. No idea why they would use such a big chip for 512 worth of data.
Found my answers. Thanks!
