Micro controllers are not new to the EP, EnterMice or SF3 use them. The Z80 is great, but needs some aid for some demanding tasks.

Joke mode: You are right, the good orthodox side of "The Force" would have been to create an interface so the Z80 could itself manage the clock generator to be enslaved by it.....

and optionally the third to replace Nick complicated clock generator (broken L2 and can't get replacement problem).
Successfully tested: Nick can run from external clock source!
29538-029540-1

Just one cut needed for separate the original 14M clock circuit.
29542-229544-3

Kvaczko planning standalone small dauhterboard as Nick clock circuit replacement. Then will be possible repair machines with broken L2.
29546-429548-5

The planned turbo card also will have a Nick clock option.

@gflorez: I do understand that. All I wanted to do was drawing attention to the contradiction between using such modern components and his earlier purist statements* in a humorous way.

*Anything built with anything else but TTL circuits is cheating. Discrete logic, ASICs and MPUs are OK, anything programmable is not.

Yes, exactly the same is what I intended(but didn't manage...) to express following your commentary, sorry. Is for that I pointed that this clock generator is not the first microcontroller-driven device we have accepted. Even the WD177X is a dedicated controller, and the Xilings CPLD on every SD-Cartridge is programmable.

Imagine what the Enterprise would have been if designed on actual FPGAs....



Edit: I forgot the GAL on every Saint's Ram expansion, it is also programmable.

Turbo EXDOS option also tested:
