Item boots to C128 mode (40 column), C128 mode (80 column), and C64 mode (only 40 column). I have not tested CPM as I don’t have an easily accessible disk around here.

I used the cartridge only diagnostics to get some assurance that the RAM and CPU are working, but I don’t have a harness for the 128 to say the system is fully working with no issues. From my testing, I didn’t encounter any glaring issues. The SID works and sounds great. Joysticks also work. I was able to load a game from disk with no issues.

Comes with computer, box power supply, and 2 manuals. Box is missing the styrofoam/card board inserts. Monitor and video cable not included.

Unit is in pretty nice shape. Please see pics to judge condition. Looks like someone drilled a hole in the left side to install a toggle switch, but never did

Box and manuals are a little beat up.

Please ask if you have any questions
