The intro screen to the BBS-game Robowar. Uses Atari’s own ascii-standard ATASCII.
Atari ATASCII graphics from here. Black box, multiplexer, your mom. Metalguy66!
Printed log-in screens from Phantasmal Alchemy, an Atari BBS in the mid 1980s. Made in Atari’s own ascii-standard ATASCII.
The BBS started rather humbly, but eventually grew to encompass a large assortment of 8-bit hardware, including two 20MB hard drives. Which, for Atari 8-bit stuff was pretty much infinite storage back then. :) The BBS was quite popular in Southeastern Connecticut, and I met many people through the BBS that I am still friends with to this day.
