This accelerator is believed to be an early prototype of what eventually became the Cyberstorm PPC. Unlike the Cyberstorm PPC which was eventually released, this version was designed to be plugged into the 060/040 socket of the Cyberstorm Mk-II. The 040 or 060 which was removed from the Cyberstorm Mk-II is then installed onto the PowerPC board, along with an additional PowerPC processor.
