What a very unusual machine: no Basic, but there was an APL subset available on cartridge. The microprocessor is the F8, a two-chip microprocessor from Fairchild, possibly a machine based on espionage. Much more in the article:
Due to the high cost of RAM at that time, the machine came only with 1 kB. However, it had 4 kB of ROM, providing four built-in programs: a simple text editor, a clock, a count down timer, and a color bar generator.
The basic computer itself does ntot have any possibility to save data, you had to buy the “Expander 1” if you wanted to have cassette tape recorder interfaces (and two RS232 interfaces). The “Expander 2” was a 300 baud modem.
