Parallel Printer Port

Platform(s): TS 1000
Date: 1984
Price: $20.95

This project was detailed completely in Syntax Quarterly, issues 1 & 2. Port is memory mapped at location FFFFh and is completely decoded. Project includes schematic, theory of operation sheeta and machine code listing comments of a copy routine for use with the Okidata ML80 and ML82A printers. Circuit and software can be adapted to most other Centronic compatible printers.

To achieve full use of the BASIC printer commands, the Sinclair ROM must be patched by putting it in EPROM.
