what i'm scraping today: microstar graphics editor for dos.
flashback to last year when I saw this video about artists from toronto who made graphics for a short lived videotex service, Telidon.
i went looking for a more detailed summary of the spec, and found this old usenet post. but my next clue was in the first few paragraphs: the author had put some NAPLPS editing software in the simtel archive (an old software archive that used to be on CD-ROM and FTP.)
so NAPLPS is vector graphics + text, with palette cycling options, and apparently some escape characters for making presentations out of different screens. there are no bezier splines, so you have to make all the curves out of little straight lines.
it feels like im designing graphics for public access or the weather channel.
learned a lot more too. started reading old news articles about videotex services long gone. discovered a NAPLPS decoder for p5.js. went down the rabbithole of different vector graphics standards used in BBS doors. too much to list here.
ok i'll share this one thing. did you guys read the tedium.co article about the silent Genesis StoryTime cable channel? the graphics were all NAPLPS being sent to old telidion decoders installed at cable tv headends.
