I had heard there's an individual that may make and sell the Octopuss cables that are used with the
COMMODORE Dead test and Diagnostic cartridges.
I ALREADY HAVE BOTH CARTRIDGES I NEED THE OCTOPUSS CABLE to interface with an NTSC Flat C128.
The individual I bought the cartridges from did not have the cable.
In the USA Bo Zimmerman runs
http://www.zimmers.net maintains CBM files in a link there be has all the ROM's for all CBM Diagnostic cartridges but no info on how
One could build this cable.
The cable is needed because it connects to all ports, if these are not connected in this loop you will get Diagnostic errors.
I DO NOT USE EBAY!!
