Accelerator Speeds

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

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

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

  SpeedTest v2.2.2 with NSC Patch. In "DSK" format.

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.
