![]() The SpeedDemon originally retailed for $295.Īccelerator II – Saturn Systems (Titan Technologies) For peripheral cards that required 1 MHz "slow" operations, the Speed Demon always slowed access to slot #6 to 1 MHz, while an on-card jumper controlled the slot #4 and #5 slowdown. Other accelerators which did not use caching operated at 3.58 MHz most of the time but had to slow down to 1 MHz for this refresh cycle. This allowed the card to use small amounts of memory, making the card less expensive to produce and eliminated the need to waste clock cycles in order to refresh the dynamic RAM that other cards used. Microcomputer Technologies (M-c-T) SpeedDemon card was the one of early Apple II accelerator which used the newer 65C02 microprocessor, and the first to implement caching technology.
