NL12 – Centronics Printer Interface to ICL System Ten Mini-Computer

1979-1980 MC6802 based design

This board plugged into various Centronics and compatible Printers such as the Centronics 1551S, Centronics Band Printers, and the Microline Series.

My board used the MC6802 Microprocessor chip from Motorola, an MC6820 PIA (parallel interface adapter chip), and a 2516/2716 2KB EPROM, although that was later upgraded to a 2732 4KB EPROM to support more features.
