RSX11M+ which of course requires the clock, so I dangled a little piece of
perfboard in the backplane (wire-wrapped to BEVENT L and the power pins)
with a PIC CPU that generated the clock. Code here:
ftp://ftp.dbit.com/pub/pic/kw11l.asm

block there. If I were doing it now I'd use an 8-pin PIC.

Can you dig up this include file in the source?
include <p16f84.inc>
I didn't find it in your /pub/pdp11 or at least not a candidate.
I saw the binary is there too, but it would be nice to have all the info
to compile it in one place in case I need it.
thanks
