PET ASCII Output Program for the Timex/Sinclair ZX81

This article describes a project which may be useful for anyone desiring to use software for the ZX81, TS1000 or TS1500 on a different computer. The program version presented here is designed to convert Sinclair BASIC programs into ASCII text which can be sent from the Sinclair computer to the serial port of a Commodore C64 computer. The program can be used with other computers if the non-standard graphic characters are eliminated or appropriately changed. In addition to the program presented here, the user will require a terminal program that permits the receiving computer to download and save text, e.g. “Plus/Term” in Feb. 1985 Compute!, and a very simple hardware circuit to interface the computers.
