8/16MHz Speed Switcher for HyperCache Turbo+ (or PlusCache ST) Accelerator Boards for the Atari ST. Written by Stuart Coates (21/02/93) This program may be freely distributed but not for profit! ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Why did I write these programs? Well, yesterday I bought a ProCache 16MHz accelerator board for my STe and the supplied software didn't really perform the function that I required. The standard software allows you to switch between 8/16MHz by using a hotkey or via an accessory. What I wanted was to switch on my ST and have it running at 16MHz without pressing any hotkeys or wasting an accessory slot, so here is the results. I've supplied two programs, 16MHZ.PRG and 8MHZ.PRG, which switch between the two CPU speeds. To boot your ST in 16MHz simply place the 16MHZ.PRG program in the AUTO folder of your boot disk and then reset your machine. If you should need to switch down to 8MHz, run the 8MHZ.PRG program from desktop. NOTE: This software may also work on other accelerator boards if they use the same method to switch speeds - try it.
