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.

Cheers,
Chuck
