ARM was bespoke round 1 -- Apple was an early investor and used ARM chips in the Newton family (also some laser printers I believe). PowerPC was round 2. Apple acquihired a Boutique chip design firm (PA Semi) that specialized in low power PowerPC designs to design its ARM cores, so the current round is almost a hybrid of the earlier two.
The 65816 (used in the IIgs) was also pretty much bespoke.
