The ATASCII font, used in Atari’s 8-bit computers.
Clip from an Atari ATASCII animation with sound from 1987. Likely first published on a BBS. It’s called Rambone and was made by Kung Fu Master. Recovered and filmed by Ryan Goolevitch. h/t Marcin Wichary.
Text-mode animation for Atari 8-bits. It uses a custom made character set so I suppose it’s not ATASCII. Or is it? Cursor art!
ATASCII animation by Alan Kirk, 1986. Also uses custom characters.
