Sinclair ZX80 / ZX81 / Z88 Forums

I think both EightyOne and other emulators support recording the screen to animated GIFs. I've used it my self to demonstrate my programs.

I'll have no time looking into it tonight, but thank you for your replies. I'll post back in a few days.

Hi It's not easy to get the picture to show on a monitor after my Phillips CM11342 CRT died. The best results I've had so far is sending the composite signal through ZX-CCB and to a 4.3" car LCD.
