TI-99/4A
Hacker Approved
Recommended for nostalgia, a well-written BASIC manual and a first taste of programming; critics say its cost-optimised design hobbled performance and its 16KB of memory is very limiting.

What people warn about
Weak design hobbled performance · 4
TI's implementation of the concept in that particular cost-optimised home computer was pretty bad
Feb 2026 · commentthe 99/4a was brutally hobbled by some bizarre design choices that nerfed its performance
Jan 2026 · commentit was designed as a game console and tried to pass up as a computer
Jan 2026 · commentTiny memory, least capable machine · 3
It gets worse because the TI99 only has 256 bytes of RAM directly addressable on its 16-bit bus.

What hackers pick instead
- Commodore 64Remembered as an affordable home computer whose built-in BASIC, manual, graphics and sound got a generation programming and gaming; critics note a weak CPU and new-model firmware lock-down attempts.121recommend
- Commodore AmigaLoved for its graphics, multitasking and video features; critics say it cost too much at launch and its custom chips limited it.60recommend
- ZX SpectrumA 1980s home computer many people learned BASIC programming and games on, praised for its quirks and repairable boards. Critics point to rubber keys and colour clash.31recommend
- Commodore Amiga 500Recommended for responsive multitasking, a large software library and good value in its era, with many fond memories. Critics say windows redraw slowly and the 50Hz display flickers.20recommend
- Sinclair ZX81A cheap 1k home computer that imposed no artificial limits and got many people started in programming. Critics find its keyboard hard to use and its tape loading unreliable.18recommend

The company sounds like a complete disaster. No, there was no arrogant strategy. There was no strategy.

The TI-99 is such a perfect fit for this too given the chip was designed for multi-user computing

turning it on and getting a BASIC prompt was real cool. never could save anything, though.

Though fun, it doesn't get used very much unless I'm playing old game cartridges.

Tape save and load seemed pretty reasonable on our system.

why pick the more expensive, state of the art 16-bit CPU* that you're getting little or no benefit from

it was a lot better than the keyboard on its predecessor, the TI-99/4 (no 'A')

a drop in the bucket compared to my friend's Apple ][. Alas.

Just use a Z80 instead of whatever mess they were using.

had a nerfed BASIC that was not only very slow

The TI's keyboard wasn't great either
