@dosnostalgic there's some history over here:

http://www.seasip.info/Cpm/drlogo.html

Dr. Logo 1.x was released in "late 1983" and thus about the same time as IBM's logo (licensed from LSCI), but it bombed in the market so hard the original disks are now lost media πŸ™ƒβ€‹

which is why i'm interested in preserving it

probably not helped by being written for CPM-86, a bare binary can be had from here:

okay interesting find pointed out to me by https://twitter.com/matthewwaller

there was a Dr. Logo 2.0

it ran on plain MS-DOS!

it was never released!

it's dated 1984, Atari ST Logo may have been derived from this version?

you can download it from the CHM
