Description

Construction Kit

Please visit this link to get all necessary information to build the A3660 accelerator board yourself. Kickstart ROMs are not included in this offer. If you need Kickstart 3.1.4 or a custom Kickstart 3.9 for your machine, please contact me and we will manage licensing.

GAL Devices

There are two options available, the original Commodore and the SpeedGeek GAL sets. The SpeedGeek GAL devices eliminate one wait-state for each CPU cycle and therefore speeds-up the A3660 board’s access times (RAM-, ROM-, IDE- and Custom Chipset accesses) between 5-10%. The good thing is, that there are no known compatibility issues by using these SpeedGeek GAL devices. Therefore we recommend to order the board with the SpeedGeek configuration. If you want to compare to the original Commodore GAL devices, you can order an extra set of the 5 different GAL devices; otherwise there’s no reason to buy an extra set of GAL devices. The difference between the Commodore and the SpeedGeek GAL devices are made up of U203, U208, U204, U205 and U207; the other GALs are the same.
