In the inside baseball realm of vintage computer enthusiasts, a few hashtags have emerged to support one’s favorite retro computers.

The main one in September is #SepTandy

While I’ve had this Tandy Color Computer 2 for many years, I’ve almost never used it. Out of all of my vintage systems, it’s the one I know the least about. I happened to have upgraded the video circuitry on it this year. It can now produce a composite signal. Now the horrible screen colors and marginal text are almost readable.

One of my first ever real programs was a blackjack game I made in BASIC on a Sharp 9300 calculator to impress my Adv. Algebra teacher. I have seen the handwritten copy of this somewhere around here recently, but I’ll be darned if I can’t find it now.

Slot Game on PC-4

Since it’s #septandy (as if that were an actual thing), here’s a slot machine on a “Tandy TRS-80” PC-4 ;-)

Back in March, we did a simple set of programs to brute force calculate Pi using a simple and well-known series. It works, even if it’s inefficient.

Speaking of inefficient, it’s September and that means it’s time for #Septandy! I have a Tandy Color Computer 2 - 16k of RAM version. There are versions of this machine with more RAM and an enhanced version of BASIC called “Extended BASIC”, but I’ve had this machine since the 80s and it is the most entry-level version Tandy made.
