I suspect that your choices for an OS are CP/M or CP/M :-).  You
can probably order documentation and/or CP/M drivers for your
devices, but you may have a bootstrap problem..you need the system
running CP/M in order to modify CP/M for the system.  One nice thing
about CP/M is that the BIOS sources (in assembler) come with it
so you ought to do okay.  I would recommend aquiring the following
items (to run on another system while getting your S-100 up):

8080 cross-assembler
Small-C (8080 version, source code is available, I have seen it in
         *very* old Doctor Dobbs Journals, and believe that some
	 user groups have it available in machine readable form).

Interestingly enough I happen to have a Z80 S-100 system running
CP/M right here (part of my collection of anachronistic computers,
I hardly ever use it, it sits next to an 8088 system which is next
to an 80286 system, which is the most modern thing I own, and only
because the University issued it to me when I enrolled).  Do not
even dream of trying to run MINIX on an 8080 or Z80 system, it is
pretty near impossible.
