It's those 104 key "unsaver" terminal layout rubberdome KBs. They are reportedly very good for domes.
But it's in no way worth $70. I picked one up for $10 last year when there was a seller who had a bunch and was asking $50. Note the nonstandard keys.
The thing is built like an F. Very solid. Has a boatload of dip switches inside and I went through all the settings, couldn't get it to talk to a PC. Of course would work with a converter.
May have other plans for the case...
