As in slower than page mode... would you have some part no. for the chips on them?

Aren't page mode chips also compatible with nibble mode ?

Total guess here but its probably that they allow 4bit access.

As for finding some, dunno sorry, could it be that normal simms are compatiable though cause I know the 72pin simms can be broken up into 8/16 or 32 bits and thats controlled by what CAS/RAS lines are asserted.

I have a GVP A3001 board for my A2000 that needs these to work,     Regular ones do not work.

Hahahaha I finally found a set of four 1MB Nibble Mode SIMMs for my GVP A3001 board, and guess what?  They are ATARI SIMMS!  Made for the TT030 computer.  Now I have 8MB on my A3001 card!

Got them from B&C Computervisions if anyone needs some.

Woot!!

:banana:

Is this the same kind of ram I would need for my GVP HD8+ A500 hd controller?
