To better track IIe Accelerator testing this page has been created. Please update the table below with your findings.

As with any page on this Wiki, use the Discussion page (link above) to discuss your findings or related topics.


History[edit]

There are many accelerators for the Apple II over the years. Their speeds and processing ability have all been highly debated. This page was created to help document their test results, and is updateable by the Community.


Downloads / Software[edit]

As other software is written it will be posted here and the comparison charts updated / added.

On July 4th, 2017 Plamen Vaysilov (Пламен Вайсилов) modified modified "Speed Test" for the IIe to use a No Slot Clock to more carefully time tests.

All testing was done on the same Apple IIe (Cooper's). The numbers shown in the ( ) are the stock baseline numbers for his machine. NOTE they are slower than the programs listed baseline numbers.
Machine Configuration: 1987 IIe Platinum, Slot0-MS Softcard IIe, Slot1-Accelerator** Slot2-A2Heaven RamFactor8M, Slot3-Uthernet II, Slot4-A2Heaven Mockingboard-T, Slot5-CFFA3k, Slot6-Vtech Floppy Controller(with NSC under ROM) and Slot7-A2Heaven VGA adapter.
