This project had been half finished on a shelf for quite some time. I finally got around to wrapping it up. The terminal is the standard text-only RS232 dumb type. It does not share a control character/escape code scheme with any other terminal that I can find and documentation on this exact model is non-existent. Documentation on terminfo files is also surprisingly hard to find but I managed to cobble together a control file that got bash working on it. The plan was to stuff a Raspberry Pi inside and have a standalone machine for doing text-only Linux stuff.

The keyboard appears to be made by Clare/Clare Pendar/Pendar/CP Clare/General Instruments (whatever they called themselves). The terminal was missing a few keys and had some broken plungers. After some modeling and a couple trials I managed to resin print a set of clones that are spot on as far as I can measure. I put them on some rarely used keys since I've not had great luck with resin durability.
