Yeah in the youtube link here: https://youtu.be/Otdy_bfPseY He talks about this. I came at it a different way which was to go between the wire guide and the card guide for the D-17B and compare. The DNA is really apparent and the D-17B is a bit later. But certain things like the setup of the flip flop logic is shared. And actually it seems like at least one board ( but in different format ) is directly shared. We actually have enough documentation to do a ‘retro’ Recomp II pretty much directly I think. Part of what is going on here is I have been looking for a carded mini type computer to build. You could almost make an argument that going for the Recomp II first would then enable one to get to the D-17B quite easily. Both would need a card ( or external module ) that simulated the drum/disk. Not impossible. Bit of the way into that for the D-17B. Really isn’t as complicated as it sounds. Just about the worst memory board one can imagine designing but doable! That advert with the two guys carrying it. Been trying to find that since I saw it.
