Vision Eprom Chip Size

[bondoexpress]

Can you tell me what the Stepper Version AM27C010-90DC What does -90DC mean and can I use different sizes for these Chips I see they go all the way to -200
                                     Stepper Game   M27C4001-10B1 what does -10B1 mean and these I see also are in 12F1 can I use either
                                     Stepper Base    M27C4002-12F1  what does -12F1 mean and these are in 10F1 does it matter which Chips I need
Any Help would be Appreciated Thanks

all speeds must be 120ns or faster
-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)

27c4001 chips DO NOT! belong in a S2000.
