Nice. Good luck on docs, though.

Speaking of those top connectors (H7-something-something-something), does
anyone have a supply of those available? I'm about to start making them
myself - I have enough to interconnect my -8/e CPU but not any of the core.
I've been working with a PDP-8/a hex MOS board (16K and 32K), but I'm not
sure if the rev of the timing module I have generates the right signals to
work with hex memory (there's an issue with CPU boards with three digits
in the handle numbers vs. four; I have some of each from two CPUs)
I'd love to remove one odd variable from the mix before I start to
component-level debug my -8/e CPU boards. At least I have this late-1970s
HP logic analyzer... I can attempt to set up stuff so it looks like
the pretty pictures in the three-volume maintenance set.
I may just order a bunch of connectors from DigiKey and make some new
interconnects. A wad of work to be sure, but at least I'll never run
out again.
