I have DOS-III, RTE-M, RTE-II, RTE-III, RTE-IV, RTE-IVB, and RTE-6/VM 
running here without problems.  I've not tried DOS or DOS-M, but I suspect 
that they should work well too.

One thing to check first: be sure that you're setting the correct CPU type 
and memory size when running these systems.  The default is a very basic 
2116 with no EAU or FP instructions.  Missing instructions are executed as 
NOPs (no-operations) by these CPUs, which will definitely cause problems if 
any of the above OSes are trying to use them.  The above systems should 
work if the CPU is configured at least as a 2100.

Please send them (ZIPped) to me directly, and I'll look them over.  
Especially please send the logs of the system generations, as all of the 
early sysgen programs would accept some invalid inputs without giving error 
messages.
