Thanks, Chuck. That was almost certainly the particular vendor I was
dimly remembering.
So it seems that the Mitsubishi "-2" parts are most likely 2MHz, but
I'll keep an eye out for NEC "-2" parts.

typically, the -2 means 2MHz for other
manufacturers...
I suspect that the -2 also means 2MHz for Mitsubishi. So you
likely got a 2MHz part.
Since I was in the same position a couple of months ago, there is a glaring
exception to this: NEC.
The uPD 8255AC-2 is rated at 5 MHz and the 8255AC-5 is rated at (ready for
this?) 4 Mhz!
