Working, excellent condition unit. Boots up without any problems and operates smoothly. I am the original owner of this machine, which has been in my family since 1984 and in dry storage since the late 1980s. This unit is a very rare, but functional unit that combines the 1984 vintage 128k unit with a 2mb upgrade so it is very usable today. The machine has a number of games and applications so you can have some fun while you collect and watch the value rise. Games include Wheel of Fortune, Buick Classic Golf, and Glider. Also includes word and drawing programs.
