All accelerators work this way. Transwarp IIe: 256k RAM on board. any writes/reads to i/o locations ($c000-$cfff, the slots on the motherboard, $400-$4000+8192, the memory mapped text and graphics screens) slow the accelerator down, access the motherboard at motherboard speed, and then resume speed. transwarp IIgs does it the same way, but it has a cache, and the CPU takes care of some of the logic as far as when to slow down/speed up. It does not have any RAM on board but somehow manages to access RAM at high speed (the CPU runs fast, and can manage 1mhz data transfer on the bus?) I'd like to see the same thing. High speed CPU on a card, with large RAM (16megabytes). Plus IDE connector on card so you can have HIGH speed disk access. How about a serial connector on the card for high speed comms. VGA port for high speed video? the IIgs MB could be used for Ensoniq audio chip, the slots, the built in hardware, 5.25 disks, 3.5 disks, etc... I'm more interested in a IIe accelerator myself. I've been programming the heck out of it with 6502 and I want higher speeds for vision processing.
