Commodore Business Machines
The 64 was arguably the best-selling home computer of its time. It ran BASIC, so people could write their own programs, particularly if they had the add-on floppy drive. (Ours has one, but it's in bad shape so it isn't pictured.) The C64 was a very popular gaming system at the time.
(True story: Julie used to work for a radio station that had one that was used to grab news headlines from a local videotex service.)
