HP 264x series terminal keyboards use hall effect sensors.

If you want to play with a Hall Effect based keyboard, probably the easiest to find are HP264x terminal keyboards. They show up on ebay semi-regularly and as I've got a good stock you're unlikely to bid against me .

Lovely photos. Is there any objection to me adding them to the terminals wiki?

There are many similarities here with the keyboards for the HP 264x graphics terminals such as the HP 2648A. However, those keyboards use a hall effect switch mechanism. No clicky noises from the switch activation because it's all done with magnets

Some pictures of various funky terminals and keyboards in the Computer Graphics Museum collection.

Yeah, I saw that earlier one as well.

Presumably you're aware of The Terminals Wiki and the Computer Graphics Museum?

Ah.... so you were the one who got them away from me . I was bidding on these too.

I got one later, but it was naked without the case.
