We still used BBC micros in the 90s for my electronics class, used to control simple circuits and LEGO robots with them.
Was there a language called LOGO, rings a bell a little?
Hahaha YES, LOGO was a programming language used for drawing geometric shapes and patters on your monitor.
The was a Turtle in the middle of the screen acting like your mouse cursor and with commands like PD (Pen Down) FD50 (forward 50 pixels) the turtle would move up 50 pixel and draw a line. Then type RT90 (Turn right 90 deg) FD50 (forward 50 pixels) and if you repeat that 4 times you draw a square on the screen.
Now theirs a language I haven't use in over 20 years and I can still remember it. Do a search on Google for LOGO PROGRAMMING LANGUAGE. It was fun in school but that's all we used it for, drawing kaleidoscopes, circles, squares etc.
