This was a triumph. I'm making a note here: HUGE SUCCESS.
I finally figured out how to use "Virtual Terminal" functionality in VisiCorp VisiOn, a graphical operating system from 42 years ago.
Took me only 29 days (mostly 1-2 hours a day after work) to go from "there is no developer documentation for this operating system, and there never were any third-party applications" to "we can make a useful application". The actual Homebrew App was made by Akko to my specifications, so it is a clear-room application implementation.
There are still a few more things I want to discover: on-screen buttons, graphics/bitmaps, and keyboard input.
The documentation for my project is mostly a "brain dump" and can be hard to read. I will write a human-readable description after I implement a game for the OS, and maybe port a BASIC to it, or something. I'm thinking of making a 2048 game, but if you have better ideas, let me know.
