I don’t get it – is it a 33mhz or a 66? And if it’s a 66, doesn’t that make it the fastest 68k machine?

It's 33 MHz. Sometimes, 68040 chips are referred to as double their actual speed rating because the clock input runs at double the main speed.
Read note 1 on your linked page:
This model is designated as having a 66 MHz processor, since theclock input runs at 66 MHz. However, the processor itself is not
"clock doubled", so technically it is only a 33 MHz processor. |

Thanx. I read the note but wasn't sure what speed it ran at effectively. Sounds like some clever marketing by Apple!

I believe it was done as a way of competing with PC manufacturers, who at the time were using 66 Mhz 486DX2/66's.

I guess 33 looked pretty slow compared to their own PowerMacs, too !
