Retro system

In 1981 I wondered if a computer is interesting.
So I ordered a kit and made it work.
The system had a board containing a Basic interpreter in ROM.
After some testing that board was removed and replaced with
a Forth-system since the Basic interpreter was too buggy.
At that time printing of listings was mainly done on a cash slip,
since that was far cheaper then A4 paper.
