Got to work on this problem a little more this weekend.  Worked up some simple standalone diagnostics to map and test all the memory on my 256K MS11-P.  Sure enough, I’m seeing some stuck bits at various addresses in physical address range 700000-757777.

Need to clean up the diagnostics a bit and add some reporting for a complete picture of what’s going on, but there’s definitely a smoking gun here...
