In other words, the database that 411 operators would consult to answer your request for a phone number in a second or two. Database lookup in a million-record or so database, in around a second, on a PDP-11 in 1978. Nice.

I have a distribution tape image of Mumps-11 v3.3 and a pre-built RL02 image which I got from the Computer Conservation Society in the UK. The images are no longer available on their website. I have no place to make them available but if someone wants to host them I can make them available (total is ~8MB).
