Keyboard
Twintest XRF-AUX AK202-1086
Twin City International, Inc. (TCI)
This looks to be a 1970's era keyboard, back
in the days of molded keycaps, discrete switches,
hand assembly, metal case, etc.
Probably not RS232 despite the connector:
DB25M on the keyboard and D?15M at
the end of the included cable.
