Roy:Sorry ofr he late responce to this question. But to get the speed of Ram vs teh access speed, you just invert the number.
200ns chips can be acess 5 Million times a second or at up to 5 MHz.2.8 MHz access time would require 357ns chips or faster (smaller number). So a 400 ns chip (I've never seen one) would be at best, marginal.

Does anyone know what the slowest speed 256K DRAMs that can be used in the IIgs one meg memory card would be? If memory serves a 1 mhz 6502 needs at least 400 nanosecond chips, so I would assume 200 nanosecond chips would be a bit too slow for the card.
