The System 80 came with a Thorn 7433 black & white TV that was used as a monitor. It had had a couple of homebrew additions.
The first was a composite video input, so modulation/demodulation is redundant.
The second was a green screen, which was appropriately agricultural. The mount has broken and in any case is too rough even for my low standards.
It seems to be working fine.
I have removed the mount, and rubbed back the glued areas. It’s currently awaiting paint and then i’ll attempt to mount some coloured perspex that looks a little more appealing.
