The original Atlas guidance computer was ground-based.[1] It was the first transistorized computer, but it was a sizable mainframe and not on the missile. Guidance was by radio control.
The ARMA Micro D is really obscure. It shows up in some lists of early computers. Apparently it was inside some versions of the LTN-51 inertial navigation system.[2][3] But this seems to have been around 1969-1970. The Concorde used that navigation system.
