Titan Accelerator IIe

“The Accelerator //e was released in 1984 by Titan Technologies (formerly Saturn Systems) and was an upgraded version of the original Saturn Accelerator, in response to the introduction of the Apple //e. The card maintained the 64 KB of RAM of the original card and added the newer 65c02 microprocessor. 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 //e”.

Platform: Apple II, Apple II Plus, Apple //e
Form Factor: 50-pin slot card
Speed: 3.58 MHz
Cache: 64 KB on board RAM + 16 KB shadow ROM
DMA compatible: No
Upgradeable: No
CPU : 65C02 4MHz / mine had: R65C02P4 II450-I4 8715

This card came to my posession with the Apple //e 65C02 “International NTSC” -board set i got earlier this year. That set was used in some old book printing house so no wonder they might have neeed some extra CPU power. Finding accelerators in Apple II’s over here is not exatly common.



In Apple II or //e you can install the card in Slot 0. Replaces possible Language 16k-card. with //e any slot works out but suggested slot is 3. There’s DIP-switches for adjusting the slot settings, time sensitive: “FAST or SLOW”.


When installed, the accelerated speed is now activated in all applications. For the 1MHz usage, use preboot disk and choose “slow down” option before booting the software disk. With CP/M card installed the Accelerator //e wont accelerate these programs. Note: Some older software might not run with 65c02 processor.


The card does what it should do, accelerate the processes nicely, but the ease of use is not up to date naturally. Using preboot disk to use the regular, 1MHz, speed is kind of annoying. Depending of your needs however, if you want vintage, old skool experience then it’s quite fine. But for modern everyday usage, there is other cards that do this easier. It’s matter of personal preference i guess.

Testing against other Apple II 8bit accelerators results:
