-
- The Falcon RAM board that was shown in the German Magazine C'T had 80nS
- nibble mode DRAMS.
- A conventional memory design using these and a 32 bit bus should give you a
- bandwidth around 56Mb/S.
-
- Note that if the bus is only 16 bit wide, then the memory is only 28Mb/S, and
- that is impossible, because the video uses 32Mb/S in the true-colour mode and
- in the 8bit VGA modes.
