I'd been having a weird problem trying to compile mkconf.c, as a first step toward
rebuilding 6th Ed, and someone suggested that it might be a memory problem. I dug out the
XXDP disks I have, ran some diagnostics, and discovered that my illusions about my memory
were ill-founded. :-) Fortunately, I had another MOS memory card, which I configured and
installed. Now cc completes with no problems, and I rebuilt the system! It was weird
that the system seemed to run fine, but a defect somewhere in the second 64k was causing a
failure in cc.
Of course, there's always a challenge. Now I'm trying to build/install a
filesystem on my big Plessey DD-11/80 drives; they seem something like an RP04, and use
the CDC 9877 diskpacks, if anyone's heard of them. I built my kernel using the hp
driver, and that doesn't seem to work with it. -- Ian
