So you're saying for a system with a MMU but no working EIS (removed for
now) and 64KW RAM (half populated M7891) you're suggesting which OS? I
still have to research the best options, RSX-11M?
I was able to get the extended three cables so I can put the M7238 EIS card
on a riser so I can probe for faults, and maybe if I am lucky boot XXDP+.
With the EIN installed I can't boot RT-11
