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. > All disc files and SimH scripts available on demand. 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. -- Dave _______________________________________________ Simh mailing list Simh@trailing-edge.com http://mailman.trailing-edge.com/mailman/listinfo/simh
