Jeff's first programming language was Atari Basic on an Atari 400, followed by Atari Assembler to get more than two colors on the screen at the same time. It was purchased from a Sears department store because there were no computer stores at the time. It was the late 1970s and early 1980s, and the Atari had 4K or RAM but no hard drive. Non-included peripheries purchased later were a single-sided super floppy, a cassette loader, a 300 baud modem and a dot matrix printer.
