I got the new tools installed (very easy- thanks to everyone who worked on that) then struggled to figure out how to build MESS. I was getting errors with TARGET=mess, but then looked through the makefile and found SUBTARGET=mess. So now I can try different arrangements myself.
The circuitry around the ROM arrays of the TMS1700 and the TMS1000 is very similar, so I think we just need a little tweak.
