Default Re: Modeline and a laptop

Hi Harry, I'm flattered that my Youtube video has inspired anyone!

Peter Scott has coaxed his video card to output the old Baird 240 line system. but it looks as if you want to go much lower than that.

I used to operate with 120 line SSTV back in the early 1980s, receiving on a 5FP7 radar CRT, and transmitting with a sampling camera based on a 625 line videcon security camera turned on its side.

I also wrote some Z80 machine code that ran on a ZX81, it was an 8X8 character generator and grayscale generator for 120 line SSTV. The last few lines at the bottom were always grayscale, just like the Robot 400, and sounded very musical to the ear too!

Anyway, I was inspired by Kat Manton, if you look up her posting history on the forum you will see she was doing the Modeline stuff with Linux over ten years ago and called the project FoTH, Fools on the Hill, which is a homage to the pioneers at the BBC in 1936.

Can you post the hardware details of laptops you are using particularly the graphics chipsets
