Quick demonstration of my SuperCPU V1 for the C64

This is a quick demonstration of my CMD SuperCPU V1 for C64.

It shows the following:
  • simple PEEK commands to detect the SuperCPU from BASIC; actually, the one that allows you to determine which version of the SuperCPU you have installed
  • a few of the integrated JiffyDOS "wedge" commands: load a BASIC program (/), save it (back arrow), and scratch it (@S)
  • a simple SINE BASIC program taken from the C64 Programmer's Guide, plotting a graph in both normal (very slow!) and turbo (reasonably fast) modes
  • and finally the incredible adaptation of Rescue on Fractalus to the SuperCPU by Steven Judd -- more information in C= Hacking #17 -- the 3D effects are amazing
Hope you like it. I shall be selling this SuperCPU 64 on eBay soon.

About the SuperCPU

The SuperCPU was first introduced by CMD in May 1996, as the Super64CPU, or SuperCPU 64, or SuperCPU v1. It was followed shortly after by a SuperCPU 128 version, also referred to as SuperCPU v2. Basically, the SuperCPU upgrades the Commodore to a 16-bit WDC W65C816S processor running at a whopping 20 MHz, twenty times the original clock frequency of the C64. It was also bundled with an optional SuperRAM Card that could hold up to 16 MB of RAM. This was an amazing technical feat, and the SuperCPU release was preceded by enormous amounts of hype and expectations. Add to this the fact that the SuperCPU was only produced in very small quantities, and you obtain a device that has achieved cult status among Commodore fans.
