That's a KeyTronic foam & foil board. Not sure what it goes to, though... KT made a lot of OE keyboards for terminals in the 80s. On Tue, Jan 22, 2019 at 11:17 PM Jonathan Gevaryahu via vcf-midatlantic < vcf-midatlantic@lists.vcfed.org> wrote:

What I haven't done so far is to power it up. And I'm not sure if the EPROM is actually original to the keyboard.
Also see http://www.citylan.it/wiki/images/9/9b/1082_readme.txt for a similar keyboard from 1979 with an older microcontroller mask rom rev, and http://kbdbabel.org/kbdbabel_doc_schematics_200904.pdf which is the keyboard from an HP-150
