Commodore 64 / 128 Multirom Diagnostic Test cartridge 586220 and others based on Versa64Cart and Harness boxed.
A full test harness is included to test Keyboard port, Serial Port, User port, Tape Port and Joystick ports. Keyboard dongle only for C64.
This Harness only works with 586220, 4.1.0 and 785260 (1, 3 & 8). Other tests may need a different harness to perform a full test and will give BAD on some tests.
Based on Peter Schepers schematic https://ist.uwaterloo.ca/~schepers/diagnostic.html
Translucent Blue Hammond boxes and extra flexible blue cable (see first picture) very helpful to avoid touching PCBs with fingers and cause ESD.
Led on user port dongle.
Multirom boxed cartridge with 8 roms (based on https://github.com/bwack/Versa64Cart )
High quality ENIG PCB for the cartridge, Gold Fingers with Beveling for easy insertion and durability.
You can choose the cartridge with DIP switches and switch.
Included also the DEAD TEST that other multi-ROM cartridges does not have. Very useful if your C64 wont boot, no need for more cartridges to diagnose your C64.
The EEPROM (W27C512) is in socket so you can change the programs on it if you have an EPROM Programmer.
Works on PAL&NTSC computers.
