More on this type of keyboard...
The "Model M3" is a singular IBM 3153 InfoWindow II Color ASCII Display Station keyboard (P/N 25H2142) that is seemingly just a PC-style Model M2 terminal keyboard with the "M3" designation. The earliest appearance of the keyboard was 1995, so given the fact the M3 designation already existed and was assigned to IBM Personal System/2 L40SX devices several years before that year, it's likely P/N 25H2142 feature a misprint on the label.
