Well, Able made a thing called an 'Able ENABLE' which allowed use of more
than 256KB of physical memory on any UNIBUS -11 with memory mapping hardware
which wasn't an -11/70-44-24. That's probably what it's talking about.
I had a meeting with Ken Omohundro on 12/7 and will be having dinner
with him again soon. I'll ask him about it. I know he doesn't have any
records left, but I could take him your notes and see what he recalls.
Also I can perhaps get engineer names and try to track them down.
I hope to get a biography and history of his companies including Able,
and figure somewhere to get it stored.
thanks

We had one on our -11/45 at MIT, BITD. So I have the programming spec for it,
back-created from the source code for that machine. And Clem Cole was nice
enough to follow up on an old message in an email list archive, and dig up
some documentation and scan it in.
I was planning on doing a page for it on the Computer History wiki, haven't
got a round tuit yet, though.
They are, AFAIK, complete unobtainium in physical form; I've been looking for
years, never seen one.
If someone wanted to upgrade SIMH to support it, we do know enough to do that.
