As an aside, isn't (wasn't?) France's
SECAM system broadcast with something
like 800 lines?
As far as I know, System E (819 lines) was monochrome only. The French
Secam system was 625 lines.
I once saw a portable monochrome TV with 3 interlocked buttons to select
between 625 lines/5.5MHz souncs carrier offet (continental Europe), 625
lines/6MHz sounce carrier offset (UK) and 819 lines/AM sound (France). I
wish I'd managed to talk the owner out of it...
I assume there were French home computers and the like with SECAM colour
outputs. Were there ever 819-line video machines?
