Gameplay footage of Get A Way, a game released in 1978 by Universal in Japan, and then a year later overseas.
Get A Way used the 16-bit Texas Instruments TMS9900 microprocessor for its CPU, making it the first arcade game to use a 16-bit processor, something its flyer proudly boasted about.

This error message in Steam is amazing, because it's from back in 2019 when support of IA-32 (Intel's main architecture from 1985 to late 2000s) finally ended on Macs.
But... since late 2020 Macs use Apple Silicon which can't run Bootcamp (as the message suggests).

Making RAM for a TMS9900 Homebrew Computer
Released in 1976, the TMS9900 was one of the first 16bit microprocessors. Texas Instruments essentially created a single chip version of their TI-990 minicomputer and was initially used in the low end models of the TI990 lineup.
However, it's most well known for powering TI's 99/4 and 99/4a micros.

I've repaired a TI-99/4A. The video chip was failing, and it was replaced. The screen was still black, I followed the trail to the CPU that had all addresses as tri-state. I got a TMS9900 from China, removed the original, put a socket made of pin rows, and et voila! #retro #retrogaming #ti994a

the 70s/80s homebrew scene missed a huge opportunity by not cannibalizing TI-99/4As to make competent computers from the TMS9900 stored within

Yeah. If you don't know what it should output you're not going to get something good. In this case it didn't understand the reverse bit ordering for the TMS9900 and when I pointed that out it wanted to add a bit reverse function. LOL
"Just change the GPIO ordering" -> "What a great idea!" Ugh

fuck i think i kinda love the TI-99/4A. im emulating this on my mister fpga rn but im really considering buying a real 99/4A on ebay since theyre still relatively inexpensive

In my lifetime it'd be a pretty straight list:
6502, 8086, TMS9900, 68K, Arm7, and Zen5
Covers easily 90% of electronics in the US over the years and Zen5 just because it so absolutely DESTROYS what people thought was affordable w/ AVX512 and www.numberworld.org/blogs/2024_8... among other things.

Mike Brent (tursilion) made an awesome TMS9900 code generator for CVBasic, so now it can target TI-99/4A computers. The picture shows Viboritas running in the Classic99 emulator. You can get the preliminary build of CVBasic from github.com/nanochess/cv... #retro #retrogaming #ti994a

For my first application of hydrogen peroxide, the bottom TI-99/4A (the one I changed the TMS9900) is now whitest than a nice one (top) 😅 and the keyboard couldn't be bothered, instead developed white streaks. You can see my old picture with the yellow tone #retro #retrogaming #ti994a

Apparently Synetix SuperSprite (1983) was among the first for the A2. More recently there was a card called VDP-1000 Plus for which there are a few references online.
Usually the TMS VDP is mostly associated with Z80 or TMS9900 systems, but clearly it has been used for other things.

Even that is cheating. I've built several Z80, a 6502 and a TMS9900 computer. But you go for it.
