MY FIRST MICRO COMPUTER 1975 !
Français Français

BASED on the Z80 from Zilog, it was able to control a Pipe Organ with 4 stops. All stops could be actionned in 16' 8' 4' 2'.
It had also a video board, able to send a video signal to any classic TV set.

I used it for developping a little game for my children.
The set, connected to a keyboard, was a real microcomputer with video output on the antenna of a conventional TV.
The video card made entirely of counter-like components and discrete circuits worked perfectly. I output a digital signal with the basics of line and image time, and
a friend had made the UHF converter in a small box apart.

Then I used it to order my first pipe organ that I had built in my house in St Gilles. The software written in assembler, (C ++ did not exist yet) allowed to control the 4 games of the organ with their harmonics in 16 '8' 4 '2'.
