Indeed. Good work Scott!

I don't think state-machines, clocked or non-clocked, is where I'd
draw the line. Having some digital curcuits doing the control is fine,
but for the CS-80 we are still not talking about CPUs. If you *really*
want, you could probably do a MIDI interface all in 4000
series... hm... hang on a minute... just taking the CAD out for a
evening out!

If this is a disease, you definitly got it!

PS. There is an Ixia box at work, but I never bothered to fiddle with
it.
