Wow, that's certainly obscure. The only reference I could find to Three Dimensional Pty's "MacComix" is the attached promo graphic, which circulated in some contemporary MacPaint collections.
Would you be willing to make disk images of the rare floppies you've been posting, and upload them for archival at the
Macintosh Garden? We do have usable copies of MacPublisher II v2.69 (
bundled with MacPublisher I v1.25) as well as
Minotaur v1.0.1b, but it's quite likely that yours are different revisions which are also worth preserving. And of course, no other surviving copy of MacComix is known to exist at all.
