The seller says it works, comes with the Disk ][ floppy drive, and various manuals. It doesn’t come with a monitor, and in order to hook it up to a present-day display, you’ll probably need an RCA composite video to HDMI converter box. Still, if you want one of the original machines behind the home computer revolution of the 1980s and a piece of Silicon Valley history — and if you can get over to Madeira Beach to pick it up — this can be yours for $100.
