When you power-up your Apple with TransWarp installed, all of the ROM from $D000 through $FFFF is copied into one of the high-speed RAM banks. TransWarp's 256K RAM is effectively divided into four 64K banks. According to the March 1986 Apple Assembly Line (volume 6, number 6) this is how the TransWarp utilized the RAM: The TransWarp ran at the same 3.58, 1.79 and 1.02 (commonly listed as "1") MHz speeds as other accelerators of its time, however, it included a whopping 256 KB of on-board RAM. In an Apple II Plus, the TransWarp emulated the 16k language card. A user could hold down the ESC key upon bootup, to disable the card for speed sensitive applications.

This new card offered complete slot configurability via DIP switches and speed control via both DIP switches and software. This card solved the Auxiliary RAM incompatibility problem of the older card, however it did not speed up this second bank of RAM which was common on the Apple IIe.Īpplied Engineering was the last company to offer a slot-based Apple II accelerator card, the TransWarp. The card maintained the 64 KB of RAM of the original card and added the newer 65c02 microprocessor. The Accelerator //e was released in 1984 by Titan Technologies, an upgraded version of the original Saturn Accelerator, in response to the introduction of the Apple IIe.

Since the Accelerator II was released before Apple Computer's introduction of the Apple IIe, while the card would run in an Apple IIe, software which required a 65C02 microprocessor or used auxiliary memory would not function properly-this problem was solved with the Accelerator //e, which was a complete redesign.

The card used a series of 8 DIP switches to configure slot access speeds as well as the speed of the card. When the accelerator card was activated, software would execute within the CPU and memory on the card, not utilizing those components on the motherboard.

The card accelerated the Apple II and the Apple II Plus using a faster MOS 6502 microprocessor and on-board high speed RAM. Saturn System's Accelerator II was the original accelerator for the Apple II series of computers. 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. Platform: Apple II, Apple II Plus, Apple IIe.SpeedDemon – Microcomputer Technologies (M-c-T) This card is the original version of Saturn's Accelerator II (thus the Accelerator II PCB shares both Saturn Systems' and NNCC's logos.) At $598, the Saturn was much cheaper than the NNCC, but little information about the board is available today.
