I guess you uysed it with the 75 interfaced to a TV screen? Right?
i mean running that with 1 line may be hard.

Right, although it could be use on the 75 only, with the video it was much better.

Here two pictures that shows it ...

Very cool Sylvain, thanks for posting these shots. I would not have guessed it's so usable this way. I experimemted with VisiCalc when I got a 75C with this ROM last year, and found it almost unusable with 1-line display as John noted. Did the display provide a full-screen image with the Text Editor module as well?
