some question about the 68k and amiga vs mac

2) motorola started the ppc series

I wouldn't put the emphasis on Motorola. They were a partner in the venture, true - but the PowerPC was based on IBM's POWER architecture, with changes to make it more suitable for microprocessor production (the POWER series were multi-chip designs). Motorola's 88000 bus was used in the first PowerPC chips, but this was mainly because Apple already had motherboard designs based on the 88000.

Actually the 601 was the first PowerPC, I think it was only 66MHz

Apple used 60MHz and 80Mhz parts, AFAICR.

it was later followed by the 603(BlizzardPPC for A1200),604(CyberstormPPC for A4000) and later by G2,G3 and G4.

Acutally, the BlizzardPPC used the 603e and the CyberstormPPC used the 604e - which were 2nd generation designs. I never saw them refered to as G2, though. Th Gx naming was Apple's doing. IBM never used this naming.

BTW anybody remmeber the 620?

I don't think this ever saw use outside of IBM RS/6000 series machines.

What about the fabled 615 which was supposed to be able handle the x86 instruction set?

Then it was 60Mhz, what wasn´t the first named something like PowerMac 6000,8000 and 9000?

My memory was indeed faulty. Apple did indeed use the 601 at a  bunch of different frequencies up to 120 MHz (I guess some of these must have used CPUs under-clocked to match a specific bus speed).

See Eveymac.com

The first three PowerMacs models were the 6100/60, 7100/66 and 8100/80 all of which used the 601.

The G2 was around the time when Steve Jobs got back to Apple

I guess the term might have been applied restrospectively to the 603(e) and 604(e) when they started using the G3 name. They never used the name G2 in any of their model names, though.
