First computer was a TO7-70, while 11yo. Fond memories from programming with the basic language from Microsoft. The machine was limited especially in color rendering: you could only have 2 colors per horizontal line of 8 pixels: one front and one back color. If you wanted to display a kind of 3D model with colors... you could not without horrible aliasing effects. The optical pen was also a "shocker". You''d regularly receive electrostatic shocks because the TV screen was electrostatically charged, and the pen had a metallic body. Sweaty fingers beware. The K7 recorder was... temperamental. The reading heads could move (heat) and make recordings not readable (infamous I/O error). You''d have to fiddle with a small srewdriver to adjust the reading head. The short summers of Dunkirk can be hot at times, and this machine was heating the bedroom pretty badly. Discovered lots of maths, years before school: Coordinates, binary and hex system, trigonometry, and the then unfathomable maths of an Earth to Moon trip trajectory simulation, all from a few example programs from a book. This undoubtedly contributed to me becoming an IT professional.

Hi everybody,

My first computer too, I had the K7 player to save and run softwares, it was so easy to copy games with that ...
To7 is really great memories for me ...

There was also somes ohter languages availiables on Memo 7 cadriges such as : asm6809 (a 6809 compiler with a small editor), forth and more...

Hello !
The TO7 was my first computer in 1983 (I was 12), and I think it was a good computer to learn programming and to make some interesting programs using the light pen.
I've bought the Assembler Cartridge to program in Assembler. It was very hard, but very pleasant once you have understood assembler programming !!!
