After some further research I believe this to be a keyboard for the 830 Series terminal.
This keyboard is also very similar to Haata's TP 130 keyboard.
and similar to nourathar's TD019 keyboard
Yeah I just love the style of these boards and others of this time period. It's been on my list for a while and really couldn't ask for a better board in my collection.
Kids are fine, job and wife can be replaced.
Oh I seen that one after it sold. The red push button is neatMMcM wrote: ↑20 Nov 2019, 15:27What does the connector look like on the end of your (presumably original) cable?
The one I just snagged from eBay (which also has a big red(!) push button in position A next to the key in position S) has a 16-conductor male that looks like it would fit into an IC socket. But only six wires, and two of them are shorted. Which is a bit confusing, since the Technical Specification says (sheet 44) that it has 6 data lines, 3 tag lines, a strobe and two non-coded function keys. Which, with power, would seem much more likely for a TTL parallel interface of that era.
Also immediately noticeable (and confirmed on that same page) is that the gray keys are 85g while the blue ones are 250g. So you're not gonna hit those by accident.
