Have lots of PDP-11 code that wrote in 1980's that can't use as no-one has written additions to PDP-11 emulators which will make one think one is dealing with 80's era data acquisition hardware and digital I/O boards which are far faster on modern microprocessors than there were then.

Well, you say that, but…..

I just ordered https://obsolescence.wixsite.com/obsolescence/pidp-11 <https://obsolescence.wixsite.com/obsolescence/pidp-11> , and it contains a prototyping area now so you can do stuff like https://obsolescence.wixsite.com/obsolescence/pidp-11-temp-barometer-hack <https://obsolescence.wixsite.com/obsolescence/pidp-11-temp-barometer-hack> .  But, I mean…that’s a modern micro that looks to the PiDP-11 as if it were a Unibus peripheral, so it’s a decent model for what you want to do.

And then there’s the Unibone….http://retrocmp.com/projects/unibone <http://retrocmp.com/projects/unibone> if you want to drop some modern stuff into a real Unibus backplane.
