Commodore 64 Dead Test Cartridge.
Designed exclusively for the Commodore 64, 64c and C128 in C64 mode.
Perform a comprehensive RAM test and troubleshoot your Commodore without removing covers, desoldering or piggybacking chips.
If you have a black, blank screen, on a C64 the C64 Dead Test can flash the screen border to indicate faulty RAM. Use on a C128 with a black, blank, screen to identify faulty low memory.
