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.
On July 4th, 2017 Plamen Vaysilov (Пламен Вайсилов) modified SpeedTest for the IIe to use a No Slot Clock to more carefully time tests.
Software With Accelerator Issues
These titles are known to have issues with some accelerators.
- PublishIt! v3
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.
SpeedTest Notes: All times are in SECONDS. TIME column is the time in seconds the test took on YOUR system. RELATIVE column is how many times faster your test results were compared to a stock IIe. Higher scored INDEX tests are better. Lower scored READ/WRITE tests are better.
NOTE: To correctly test the UltraWarp you must do the following steps BEFORE testing.
- Boot SpeedTest disk and load the SpeedTest program.
- From the SpeedTest menu exit to BASIC.
- Type CALL-151 and press Enter.
- Type C081 and press Enter.
- Type C081 again and press Enter. (both times are required)
- Type D000<D000.FFFFM and press Enter.
- Type C083 and press Enter.
- Type 9DBFG and press Enter to get back to BASIC.
- Type RUN to restart the SpeedTest program.
If you are testing an UltraWarp and do not perform these steps the program may not work correctly.
