Notes from Greg Croxton:

The Robin was an oversized VT-100 with the motherboard mounted inside the CRT case.  The keyboard and floppy drives were separate.  Mine was a "super PC" because it had four floppies.  The OS was CP/M.   They were manufactured abt 1982. Though available only to DEC employees, I got one through a contractor who was working with me. This one stopped working the last time I moved (1986), but according to the error message, I think the only thing wrong is a loose keyboard receptacle.
