[Coco] Re: "Historic" CD-i development systems...

[Richard E. Crislip]

Hello jdaggett at gate.net

I never knew that MACs used the 060. I thought they stopped with the 040
before moving on to the PPCs. The Amiga, however; did make use of the 060
and some of them were clocked at 75mhz. Mine runs at 50mhz.
