DT-80: Eighty Column Dumb Terminal for the ATR-8000 © 1984 Amiable Computer Enhancements.
DT-8O is a cartridge designed to give ATR-8000 CP/M users access to a full 80 by 24 screen without the expense of an 80-column board. DT-80 uses the Atari's internal display hardware to show remarkably legible characters in a 4 by 8 matrix, allowing the full 80-column screen width.
