I’ve been building a VT100-style terminal project on a Pi Zero W using Circle (bare metal, no Linux userspace).

I also built dedicated matching hardware so the software feature set is usable as a complete terminal system.

It’s also a perfect fit for Michael Gardi’s 60% VT100 replica concept: https://www.hackster.io/Megardi/2-3-scale-vt100-terminal-reproduction-696b89

I just published v2.3 with a consistent release + docs.

Technical highlights:

- broad VT100/ANSI/DEC parser + renderer coverage

- ROM-derived VT100 font families and graphics charset support

- strict WLAN session separation on one endpoint (:2323):

 - Log Mode (diagnostics/commands)

 - Host Mode (raw host bridge)

- reproducible release assets and deployment guidance

Deployment baseline:

- copy complete VT100/bin contents to SD

- adapt wpa_supplicant.conf to local Wi-Fi
