New video: TND232 Tandy Serial Port Soundcard

The Tandy 1000 and IBM PC Jr utilized the cheap Texas Instriuments SN76489 programmable sound generator. While it never caught on as a sound standard outside of these machines, many DOS games from the 1980s still supported this chip. What if you wanted to listen to video game music using the original chip, no emulation, but you had only a serial or USB port?

#FujiNet - a WiFi Adapter for many #retrocomputing and #retrogaming systems. Coming soon for #MSX.

Also for #Atari8bit, #Apple2, #ColecoAdam, #TRS80CoCo, #MSDOS, #Commodore, and more.

Four years ago I wrote about a TRS-80 game from a (probably) Scottish author that had character-text errors that made it unplayable. The game is now repaired for the first time, and I play it through and discuss its context as a "learning" game.

I recently gave a talk at #VCFSoCal2026 on the state of the #FujiNet WiFi Adapter for #retrocomputing and #retrogaming systems

Platforms covered: #Atari8bit #Apple2 #TRS80CoCo #MSDOS #MSX #Intellivision

also new apps, testing and volunteering!

TIL that the #IBMPC didn't come with just #MSDOS. It had *four* operating systems available from the start.

I imagine that's why it was designed to boot from disk, and not a fixed ROM operating system like the #Macintosh.

The four original IBM PC operating systems were:

* #ROM #BASIC
* UCSD p-System, an OS built around a #bytecode interpreter for #Pascal
* CP/M-86, an x86 version of #CPM
* #IBM PC #DOS, a knock-off of CP/M from a little-known company called #Microsoft
