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.
Excellent news. (Sorry I've gone quiet - I got distracted from the analysis
effort by trying to finish up the -11/34 ucode transcription effort.)
Is it really an MS11-P? Those are EUB memories; I don't recall offhand if
they (like the MS11-M) have a jumper to configure them to operate on the
UNIBUS.
