Does anyone have a distribution image for MUMPS-11?  I’d love to get it up and running under SIMH.

A distribution tape and an RL01 image are available on  bitsavers.org in bits/DEC/pdp-11/dsm-11

Some of this will be a repeat of what others have already shared here. Every time I see mention of MUMPS-11 I follow the links, download and archive a copy of what I find, and keep notes on where I found each item. Following is a summary of my notes on what and where I found those items. If you find any of these links are now dead, I will be happy to share my local copy. Note that I did not grab a copy of the videos or Open SIMH listed in the last group, "DSM-11 videos". Note that I haven't tried using any of this and that while I'm interested in MUMPS, I've not yet used any flavor of MUMPS.

I hope this helps.

A copy of the disk image is at

Feel free to put it on more stable archives. It appears to be a freshly
genned system.

is another source for a manual. It's the version which Micronetics sold, of
which I heard "Micronetics shamelessly copied DSM-11 practically line for
line to the PC." So the manual is probably close enough to work.

As if MUMPS isn't fun enough on modern systems, how much fun can we have on a PDP-11?

Thanks for the pointers!

I had been looking specifically for the older MUMPS-11 distribution, but I think I’ll go with DSM-11.

I worked at a company in the late ‘70s that had a MUMPS-11 source license and thought I might reacquaint myself with the environment.😀

I would love to see the source for DSM-11. I would imagine the very low level stuff was borrowed from a contemporary DEC OS?
