My parents bought a second hand Tandy 1000TX in the early 90s, largely for my use. I remember being excited playing with the Deskmate music software, but that did not last long. After about two days, the Deskmate disk became corrupted, and I was never able to get the disk working again.
Still programming 27 years after I started. I'm lead of a group of front-end developers using AngularJS to build an online marketplace for hospitals to purchase their supplies.
It worked quite well, and I remember taking sample of various thingies and making music.
I also did as the article says - putting the samples on the sonatina because it was quite funny.
That should have been the star feature of the computer. Too bad the sales team didn't focus on that.
(I wonder if someday I'll be able to play back these tracks that I must have saved somewhere?)
EDIT: correction from the article: they seem to have used the mouse controller, not the joystick controller, cf the project manager post on https://groups.google.com/forum/#!msg/comp.sys.tandy/fq1OO44... and further interesting technical details
