morning coffee musing: could you make a discrete computer (7400 chips, but the modern versions with fast slew rates and all that) that can run at triple digit MHz?

@Extelec In theory, if the switching rate is fast enough, the return paths will hug the forward signals, so that part at least should be the same design rules as everything else. Reflections off stubs and impedance discontinuities is likely the big killer. I know people design stuff like that all the time, so there must be known techniques for managing it. Or maybe everyone just reaches for a field solver and iterate based on simulation data.

@danderson there's always Potato Semi....

@mxshift Is... is this for real? I'm genuinely having trouble telling if these are real things I can buy
-
@danderson I bought a few chips from them a few years ago. No idea what the state of their business is now

@mxshift Well the ebay store seems to be no more, and half the distributors no longer exist and the other half don't advertise their products. It doesn't look great... otoh that could just be small company vibes.
