This is the ZIF (Zero Insertion Force) socket version of the Premium Dual Diagnostic cartridge.

The idea behind this cartridge is for those people that want utilize the wide variety of Commodore 64 diagnostic eproms available on the internet without having the bother of buying an individual cartridge for each image.  This cartridge supports both the regular diagnostic images as well as the deadtest image.

This version includes a built in reset button as well as a toggle switch to go between the deadtest image and regular diagnostic images.  The cartridge is identical to our dual diagnostic cartridge with the exception that this cartridge offers a ZIF socket.

This is a gold plated cartridge.  Unlike the boards with the "tin" style cartridge edges, this version won't damage your cartridge port by wearing and clogging your port.  Further, it is designed to fit in a standard cartridge shell that supports a center screw.

This unique cartridge includes both the 781220 diagnostic cartridge, as well as the 586220 dead test cartridge (EPROM INCLUDED).  Both of these cartridges are available to you on this one cartridge.  Images were obtained from and publically available on the internet.  Simply flip the switch to toggle between the two.  This cartridge also features a power LED (indicating that your computer is supplying voltage on the 5V line).

Works on all Commodore 64 Models. 

This is the Cartridge you'll need if your Commodore starts with a Blank Screen or even if boots with some defective components. Identifies what chip/chips need to be replaced. 

Works on both NTSC and PAL computers.

This is the same Cartridge that was used by Commodore Technicians to repair faulty Commodores. Dead test can take 20+ seconds to boot up).
