Commodore 64 Dead Test & Diagnostic 2in1 Cartridge.

 

A brand new fully assembled and programmed, thoroughly tested Commodore 64 Dead Test & Diagnostic cartridge. Made in the USA.

 

This is a 2 in 1 cartridge, insert one way for Dead Test revision 781220 and the other way for the latest Diagnostics software revision 586220*.

 

We sell all types of dead test and diagnostic cartridges.

The main difference between a dead test and a diagnostic test for the Commodore 64/128 is that the dead test is a little slower but uses Ultimax mode – which allows it to function without working ROMs / Kernel in the host computer. A diagnostic test is similar but checks the stack and zero page more quickly, performs more extensive RAM tests, and tests the ROMs. To pass a diagnostic test, a Basic Kernel and character ROM is required. A diagnostic test can also be used with a diagnostic harness consisting of numerous dongles that will also test the hardware ports of your Commodore machine.

In short: a dead test cartridge has more chance in starting up and indicating something if there is a bad fault but a diagnostic test cartridge is faster, more thorough, and can be extended with a testing harness.


Quickly diagnose your faulty Commodore 64 with this simple, high quality easy to use cartridge.
