ISO: PDP-11/40 LTC and Stack Limit options

Hi all --

I'm finally turning my attention back to my 11/40 (which I started working
on 7 years ago and never quite got around to finishing -- I've learned a
lot since then and I'm hoping to be able to debug it properly now).

My ultimate goal is to run V6 or V7 UNIX on it -- I have the MMU but I'm
looking for an M787 (line-time clock) and M7237 (stack limit register) to
complete the set.  I have other DEC stuff for trade, drop me a line...
