I had never heard of these machines until one came up on /r/retrobattlestations and I just had to have it.
The Basicalc is one of the early programmable calculators that was starting the trend in handheld computing from ‘calculator’ to ‘computer’. The TRS-80 PC-1 is another great example.
The TI-74 has a working BASIC interpreter, as well as the standard calculator functions. It also includes a ROM Module slot that allows for plugin expansion of pre-packaged applications.
- TMS70C46 CPU
- 31 5×7 character LCD
- 32+4 KB ROM
- 8 KB RAM
- RAM/ROM memory expansion port
- Hexbus port
- 80 characters per line (31 visible)
- powered by 4 AAA-size batteries
Happy to have this in the collection!

Just today I found one of these in a flea market and as a vintage computer collector I should say I love it. I have been writing short basic programs all the day. Now I need a CI-7 interface to connect a tape recorder and I will be a really happy man.
BTW, Cool blog!
They’re pretty nifty. I haven’t done any long programming on it yet, I just wanted to make sure it worked and I could noodle around with it . So far so good! Glad you’re enjoying it (and the blog 🙂
Hi Vhzc, I know it’s quiet a long time since you launched the request but if you are still in search of a CI-7, I’ve got one. In fact I used a TI-74 basicalc, with the CI-7 interface for recoding programs and I also baught a 8K memory extension as well a Mathematic Library extension. I finally baught a TI-95 Procalc. All in their own box+user book. Interested ?
