Mystery: George Risk (GRI) KBM-DIN

[Daniel Beardsmore]

Something else I found in the GRI catalogue, is two keyboard modules that use KBM-DIN, a "DIN compatible" switch. All you can see is its profile form in the diagrams. It has 10M lifetime, gold contacts and it's tactile.

I've asked GRI if they have any left or have any details on it, as it's not in the catalogue. I assume it's something they bought in from another manufacturer. It looks almost exactly like Mitsumi miniature, including the short depth and rear-offset slider, so my guess is that we've now obtained the lifetime of Mitsumi miniature.

Interestingly the cover shows a full-size late 80s/early 90s–style beige keyboard that's not in any catalogue pages.

[Edit: KBM-DIN, sorry! And still no word from GRI at all.]

I am not sure on the advantage of DIN-compliant switches in a keyboard that size.
