This talk of making flip-flops brings to mind a topic not mentioned
much at all any more--that of AC-coupled logic. Does anyone own any
CPUs constructed using this logic type? I realize it was more common
when thermionic devices (tubes/valves) were used, but I do recall
seeing some transistor and tunnel diode circuits using AC coupling.
Are you referring to AC-coupled/triggerred flip-flops (where the clock trigger
is applied thru 2 capacitors to the input of each side of the FF) or to logic
where all signals (gate inputs, etc.) are AC-coupled?
