My first computer was a Heathkit ET6800 Microprocessor Trainer, using
an 8 bit Motorola 6800 (note only two zeros) processor and 256 bytes of
RAM, with about 40 bytes reserved for the operating system:

Input and programming via hexidecimal, output via six 7 segment LEDs. I
soldered an amplifier onto one of the LED segments, programmed the
computer to turn that segment on and off at programmed frequencies, and
created a "computer guitar". This experience led me to become a
programmer.
