Still a work in progress, but most functions work. See the 'readme' file for more information.
You can use the same ROM and GROM image files as for V9T9 or MESS (I had to rename the MESS file '994agrom.bin' to '994agrom.gpl' in order for it to work).

Requires: Macintosh with 500 kb of free memory, system 7, and Color Quickdraw
Download version 0.2.1a2 (11/7/99):
(Note: Since I have been doing poorly at keeping up with all of the new versions of MAC V9T9, I am not keeping a copy of it for download on this site, and I am directing download request to the author's web page.)
