So I was recently provided (thanks!) with a copy of the later rev of the
PDP-11/24 Tech Manual (EK-11024-TM-003), which I have had scanned for a while
now (waiting for a quite period on the list ;-), and is now available for
upload here:


(Bitsavers et al, please pick this up and distribute.)

So it has an Appendix D, which described the -YA later rev of the CPU card
(in which a bunch of gates were replaced with a couple of custom gate arrays.
Does anyone have one of these? I'd love to get a photo of one, if so.
