Simple BASIC commands functioned properly. When inserted, the Super Expander was shown to add an additional 3K of RAM to the system. Cassette tape player powered up when plugged in, and the mechanical parts seemed to work properly. I was able to write a simple BASIC program, record it on the tape, load that program into the system's RAM, and execute it. Any functions of the system that are not listed above were not specifically tested.
Notes on the physical condition of the items: Contents all in good physical condition, no major damage. May have small dings/scuffs here and there but nothing that I observed beyond slight cosmetic defects. Computer base unit tested and working. Cassette player tested and working for recording and data playback functions. RAM expander tested and working. AV cables, power adapter, RF unit all working. Box has significant wear - it is entirely intact, opens and closes and stores the console but has lots of shelf wear, tearing, cardboard damage. In general, everything looks like it's in very nice shape and was maintained very well by its previous owner! Box has one piece of foam and the inner box that holds the accessories.
