The m40.s here is purported to support 7th edition Unixon the 11/40, 11/60, and 11/23.  It has, in fact,worked on the latter machine.The param.h is included because various sizes have tobe cut down considerably; this is a guide.(Things will be tight!  You might consider removing some system callsyou don't care about, like accounting.)Also, it is necessary to remove the	.datafrom line 3 of the l.s file, because the interruptvectors and such should go in I space.Support is included for FP11-style floating pointbut I can't vouch for it.
