Scot's ZX80 Site

Welcome to my modest little site - dedicated to the mighty ZX80! Most of the resources here have been obtained from various places on the net - and where I can I've noted the source. The remainder is from my personal collection. I believe them all to be in the public domain but if anyone does own the copyright to any of the material here please advise me and I'll remove it.

There's a dearth of software on the net for the ZX80 and I'm particularly keen to expand that part of the site. If you have any listings, .o files or .wav samples you'd like to contribute please send them in and I'll list them. Thanks :-)

Space Invaders

This is a brilliant programme which solves the screen display shut down problem by calling the display routine frequently through out the programme. It comes with many of the emulators, although the listing is from
