Wondering if plain-old wire-wrap connections can even handle the kinds of clock rates that would justify using 74F series logic instead of plain-old low-power Schottky. Would I have ended-up with a nightmare of crosstalk and RFI, both incoming and outgoing?In theory, 74F logic should handle clock-rates up to 100 MHz, but I'm guessing it would take years and years of fiddling to get it stable at even 1/3 of that. Fairly sure PCB prototypes that big would cost in the triple digits for a small run, for each iteration, and several iterations would almost certainly be needed.And in the end, it's a very complicated toy that's less useful than the simplest microcontroller, until a similar amount of effort goes into all the other boards required before it will actually work as a computing device. At which point, it will still be an inert box. It would need a cross-assembler hosted on something else, then it would need a ROM monitor, before I could even think about trying to port something like the XV6 kernel to it, then cobbling-together a bit of a userland and a native assembler. A self-hosted compiler is probably a bridge or three too far.
