Those who were already impressed by the SYSTest64 Cartridge will also appreciate this C64 Diagnostic cartridge. With this new "C64 Analyzer Cartridge," even more possibilities are available without the need for a C64 monitor screen.
This not only simplifies repairs without special electronics for "Black Screen" defects on the C64 but also allows for convenient on-the-go testing of a C64.
Signal or frequency measurements, which usually require an oscilloscope, are now largely a thing of the past because all important signals and frequencies are precisely measured and displayed directly on the OLED display. Short circuits and pull-up resistors are also rudimentarily checked.
Additionally, the PHI2 Delay time in relation to PHI0 is displayed in nanoseconds.
The entire memory test, as well as ROM chip tests, are now also possible without a C64 monitor.
In addition, the C64 startup sequence after a reset can be compared with an original byte sequence. This can be used to test whether the start/reset process is working properly or whether there are any problems.
The module can also be connected via USB to a computer with a local HTML website that can display further information in a Chrome browser:

In addition to these basic functions, work is underway on further features and tests that will be implemented in new firmware versions.
The board is delivered fully soldered.
The firmware can be easily transferred via USB.
(Firmware update: If the menu cannot be operated with the Up/Down buttons after the firmware update, you must switch to another firmware mode. To do this, press and hold any module button before switching on the C64 and release it after approx. 1 second after switching on)
