My first exposure to a computer was a Digital Equipment Corporation (DEC) PDP-8/L minicomputer belonging to my high school. It had 4K 12-bit words of ferrite core memory, and a Teletype ASR-33 with paper tape reader and punch. We had a tape of the FOCAL-69 interpreter, so that was the first "high level" language I learned.
Later my school rented a Wang 2200 minicomputer, which natively ran BASIC, and used a high-speed cassette tape drive for storage.
Next they purchased a PolyMorphic Systems Poly-88, an S-100 chassis with an Intel 8080 microprocessor and a floppy drive, also running BASIC. I wrote my first version of Lunar Lander on that machine.
