Well TattleTech says it's an 8MHz Mac Plus. But I bet it's just pulling the CPU speed from a reference table, not actually measuring it.

Oh man, I had forgotten how painful disk swapping was. I think I had to do about 15 disk swaps to launch TattleTech. And that was after 20 minutes of ferrying files between disks on two other computers just to get the TattleTech program onto an 800K disk.
