The daughterboard on the one in question has a 6402 on it, so can be expected to be a parallel to serial converter.
The daughterboard also has what appears to be "Ditronics" labeled on it.
A search turns up a currently existing Ditronics doing financial-world tech services, no idea whether it could trace back to the 80s keyboard.
