This particular diagnostics cartridge does not require a test harness, and are specifically useful when your C64/128 has no picture.

What sets this cartridge apart from the other test cartridges, is that they all require the RAM to be functioning to boot,

(unfortunately, one of the most common fault is defective RAM) This cartridge not only work with defective RAM,

but it also can tell you which RAM is broken. The reason why this is possible, is that a correctly made DEAD TEST CART will require the system RAM,

but it will instead temporarily overwrite the kernal ROM bypassing a lot of functions needed to boot the computer.
