MouseDESK - attempt at GUI on a TI-99/4a in 1987/88

This is my attempt at writing a GUI for the 99/4a in 1987-1988.. This runs on a TI-99/4a with 32k RAM expansion, Mechatronic Mouse and Extended Basic. I also ported it to the Geneve with the Geneve mouse in GPL mode with TI Extended Basic.

It will load programs in Extended Basic and with loaders it will load EA Option 5 programs as well (demonstrated). Has a mouse based character editor, a font editor and loads "custom background patterns" and different font sets.. note: the shareware notice has my old address and is no longer valid, and yes I see the YOU'RE that I never fixed :) ... https://www.youtube.com/watch?v=mhafwKxP5E8
