Text video display for 8bit computer

A simple and handy 40x25 monochrome text display you can attach to your 8bit computer (based on Z80, 6502 etc.) as I/O device with parallel data bus.

(Picture is (C) Daryl Rictor)

A great device by Daryl Rictor - a part of his 65C02 works. The interface is an 8 bit parallel port with a strobe input and a busy output. It can be connected directly to a 65C22 8 bit port or any generic parallel port with ease.
