Z8000 parts question

Only a very minor detail, but I beleive that the certain Zilog chip
designations also indicate the max clock speed. For instance the
Z0800110PSC is a Z8001 (Z08001.. portion), with a max clock speed of
10MHz (..10.. portion), and the PSC indicates a palstic DIP package. So
I would guess that the CPU, clock generator, and MMUs are 10MHz, and the
Z-CIO is 6MHz. The Z-SCC is probably an older chip that predates the
current Zilog chip designation standard.


> Z0800110PCS CPU

Central Processing Unit, 4.0 MHz segmented version (8 MB addressing).


> Z08030AB1 Z-SCC

Serial Communications Controller (dual channel), 6.0 MHz.


> Z0803606PSC Z-CIO

Counter/Timer and Parallel I/O Unit, 4.0 MHz.


> Z0801010PSC Z-MMU

Memory Management Unit, 4.0 MHz.


> Z0858110PSC

Clock Generator and Controller, 6.0 MHz.
