-90 is 90ns, -10 is 100ns, -12 is 120ns, ns = nanoseconds (lower number is faster) 27c010 is also a 27c1001 128kilobits x 8 bit Schematics show either 27c801 or 27c080 - 1 megabit x 8 bit for the SG, GME1 & GME2, or game chips 27c4001 does NOT sound right for the two game chips 27C4001 is 512Kilobit by 8 bit note the game chips are interleaved so the game OS can be a 16bit OS. 27C4002 is also a 27C4096 both are 256Kilobits by 16 bit do not even think of using a 27c4001 for a base chip (512Kilobits by 8 bit) Title: Re: Vision Eprom Chip Size Post by: coorslight115 on September 15, 2011, 10:47:20 PM 27c4001 chips DO NOT! belong in a S2000. :60- :60-
