Well, IBM's own literature (which I no longer have) called it a
microcomputer.
I remember well, because I was building equipment for automation of some
manufacturing and testing processes for analog electronic components, using
the available technology of the time, so I was studying all on which I could
get my hands.
The systems I built used what DEC called PDP-16, a family of hardware
components with which you could build customized systems. We used binary
data to drive this equipment which was read from a Mylar 8-channel punched
tape which was generated by the 5100 via its RS-232 port.
In those days, I was as big a fan of APL for the kind of work I was doing
as I am of Ada today.
