Glad to hear! 😀 On my PC/XT clone, I'm currently trying out an interesting Personality Analysis Program (analyze.zip) from retroarchive.org.
Among my favorite books is PC-Bastelbuch (PC thinker book, #3-89090-331-2) by Kai Hamann, which focuses on game and Centronics port.
Not sure if it ever got translated into English, though. Author Burkhard Kainka (transl.) also wrote some entertaining electronics books,
which I think some of got English releases.. The early releases focues on serial/parallel and include code for Pascal and GW-Basic, I recall.
Oh, and also check books for Quickbasic.
QBasic is derived from QB 4.x, so books about QuickBasic 4.0 or 4.5 (or earlier) may also work,
provided than no advanced QB-exclusive features are used (rarely the case IMHO).
Same for Visual Basic for DOS, which was a mixture of QB4.5 and Visual Basic 1.0.
The syntax of VB DOS or VB DOS Pro is very close to QB, and I got most of my programs to compile with it.
Last, but not least, there's PDS Basic 7.1, which is sorta a hybrid of Quickbasic and M-BASIC, I believe.
It supports EMS, OS/2 and such. But there aren't many books about it, so QBasic or QB is fine for most.
Last but not least, there were special builds of GW-Basic, which used the advanced features of the Tandy 1000.
Not sure about graphics, but they definitely supported the 3-Voice chip!
@infiniteclouds I'm still looking for a Tandy 3-voice Host software for MIDI.
Even if it turns out there isn't yet, people like YT user Bisquit might be able to implement it.
(There's seemingly quite an interest in retro programming for sound chips,
so there must be still enough knowledge and information left, see https://youtu.be/gjuHxjdv3ZE).
- I also apologize for going slightly off-topic in your thread; it wasn't on purpose. I hope you don't mind. 😅
I just hope that this -um- extra information might be useful for you and other Tandy 1000 users, at least.
