The 32k trannies represent the cpu, but an actual 610 uprocessor tends to be built with other things added. For example, the 610 for the newton started life by grabbing the 610 cpu module and sticking it in the corner of the silicon. Then a large object-based mmu with hardware garbage collection was designed and added. All in all far more than 32k trannies. The 610 is simply a core around which final uprocessors are designed. james
