OK, since it's quiet...

How many people have had dealings with the Honeywell DDP-516, or related 
machines? I know one version of the 16 series was the ARPAnet TIPs, but 
I'm wondering about the ones that weren't.

I played with one a bit back in the early 1970s - I implemented a program 
on it (a very portable one, but that was my first):

  http://www.ml1.org.uk/impl-i.html

Unfortunately I never kept source code, although it would be trivial to 
do it again.

More interestingly, I modified the CPU! I changed the effect of soem 
instructions to make it more suitable for virtualisation. More here:

Perhaps this will stimulate a bit of discussion.
