Apple went PPC with Power Macintosh 6100(60 MHz 601), 7100(66 MHz 601) and 8100(80 MHz 601). They were out during 1994.
But I remember back then, that Apple 68k built-in emulation was so slow (even slower than many 68k Macs), that many mac users kept using their 68k Macs for some time despite PPC Macs were already out there.
Funny, I also remember that in those Apple 68k to PPC transition times, the fastest Mac was actually an Amiga running Shapeshifter!
