While searching around on the net I found these at this site...

But there is no info on what they are.
They look like some kind of ZX81 clone with an old PC game port interface.

ZX81 clone or what?
Re: ZX81 clone or what?
I'm wondering if they are just keyboards.... Perhaps used for something other than zx81... The D connector has enough pins for it just to be the keyboard matrix. An interesting find anyway.

Re: ZX81 clone or what?
Yes, my thinking is along the same lines as Andy's comments.
A ZX81 membrane makes a very convenient keyboard that can be used for other applications.

There are four lights!
Step up to red alert. Sir, are you absolutely sure? It does mean changing the bulb
Looking forward to summer later in the year.
