Hi Phil
Thanks! That will help quite a bit. Even though the hardware is somewhat different the protocol should be the same and that's what I am seeking.

The Z80 PRINT V1 board is based on a IBM PC compatible bi-directional 25 pin parallel port built from discrete logic chips rather than a PIO.

This is the same circuit as is present on the ECB CVDU board if people remember it. I don't think anyone ever wrote driver software for the parallel port on the CVDU which is a shame but understandable since parallel printers have gone obsolete for some time now. If anyone does have a parallel port driver for CVDU please let me know.

Thanks, Andrew Lynch

PS, the rest of the parts I needed for the Z80 PRINT V1 board arrived yesterday so I can finish building mine. Looking forward to some testing
