Multibus seems to be the fringe of vintage computing now but was a popular
bus in the past. From my perspective it was more popular with 
industrial/embedded systems.  S-100 was more business/home. I did a couple 
cards for it before we switched to VMEbus. We did some complex multi processor
systems with it for radar simulators among other things.

It was long enough ago details a fuzzy but my memory is it wasn't that
hard to implement the interface. Multibus will allow you to
explore an interesting corner of vintage computing that isn't getting
that much attention. S-100 your going to find more people who can help if you 
have questions/problems since its more active now.

I think I have an old Multibus bus probe that was uses for troubleshooting
I could loan if you don't have more modern equipment that would be better or
just want to play with it.
