The MX-80 (and FX-80) were among the least expensive of widely available
dot-matrix printers that could also do graphics.  Hence the wide appeal.

IIRC, the MX-80 had serial (RS232) as an option with Centronics
standard.  The interesting thing was that the only thing the option
really gave you was the EIA-to-TTL level shifting logic.  I recall
cobbling an adapter up using a couple of 2N2222 transistors and a 9V
