Re:Again...more ram!

Like both your idea and the manner in which you detailed/justified.

My firm is nearing the completion of a low cost device which talks to LMI devices via an 8 bit parallel bus - and provides ALL of the glue-logic to directly attach various sizes/types of economical Sram. Plan to introduce 1st as a small "daughterboard" - later will provide either/both custom ic and ram for your own population.

Key appeal of this approach is that ALL LMI devices can employ large, bulk Sram and optimal transfer rates. (plus several other, desirable "goodies.")
