Whoa, I spy an ESC key where the TAB key goes on modern keyboards!
Could it be an ADM-3A???
(Or rather, a variant, or related terminal? Maybe that escape key placement was more widespread than I initially thought.)
Based on my experience from 40 years ago, a problem could be the keypads... our one developed delamination even back then. Plus the optional "16kb rampack" got a bit glitchy! Good luck!
