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.


Accelerator Comparison[edit]


Accelerator Speed Results Using "SpeedTest" for the II/+/e/c.
Notes: Some IIe systems may be slightly faster than others. Run the SpeedTest program from a Mass Storage controller can influence some testing. All testing should be done from a floppy disk for most consistent and accurate results to the chart.
