This is the Revision 781220 of Commodores Dead Test diagnostic cartridge for the Commodore 64.

This is THE cartridge you need to test "dead" C64's! It WILL boot the machine and run standard factory tests. If it will NOT boot at all, there are flashing screens to tell you what the problem may be! Are you interested in getting into vintage C64 computing? If so, then you will want to have this tool in your toolbox! Invaluable for determining the status of main boards and chips.

Rev. 781220. Located at $E000 in memory(Ultimax) and boots before kernal ROM. ROM provided is a NOS ST ROM 64k that is reprogrammable (with eprom eraser and IC programmer, not included) if you decide to do something else once you fix your Commodore 64.

YOU MUST NOT CHANGE THE JUMPERS ON THIS CARD UNLESS YOU ARE REPURPOSING IT WITH ANOTHER IC CHIP. IC SIGNALS ARE PROTECTED WITH 10K OHM RESISTERS TO PREVENT HARM TO YOUR MACHINE.

IT TAKES APPROXIMATELY 20-30 SECONDS FOR THIS TO LOAD INTO THE C64. THIS IS NOT A CARTRIDGE LIMITATION RATHER THE WAY THE MACHINE CODE IS WRITTEN ON THE IC AND IT IS EXACTLY HOW IT IS TO FUNCTION.

Assembled in the USA (Delaware) and will ship same day if ordered before 3pm.
