And they could have claimed the 11/45 was a 33MHz machine (that is the 
frequency of the master clock crystal). It always amused me that my 11/45 
had the same clock frequency as 386 PCs some 25 years later.

Of course as _we_ all know, clock speed is not a particularly useful way 
of determining the speed of a machine.
