As I recall, this shop was run by Eric Shepherd up until 2011 [1] before he transferred control to Tony Diaz.
Shepherd is an author of many fine Apple II and Apple IIgs apps, including the excellent IIgs emulator Sweet16 [2]. Now, he's a technical writer for Mozilla. Awesome guy.
Diaz... runs Apple2.org [3], and I'm ashamed to admit I'm not aware of anything else he's done for that community. If anybody else could fill in, feel free.
