are the IBM PS/1 model 2011 and 2121 monitors interchangeable?

[DaveJustDave]

These are the PS/1s that have the power supply for the computer built into the monitor. Does anyone know if a monitor that shipped with the newer 2121 (in this case a 386sx-20 model) fit the older 286 based 2011? the connectors appear to be the same, but i'd rather not fry something on the off chance IBM decided to change pinouts and voltages.

thanks in advance!

I think they are the same unit.
