Got DSM-11 running, any manuals online?

I have DSM-11 V4.0 (or it may be 4.1?) on a TK50 cartridge somewhere. When I manage to get my MFM emulator board playing nicely in my 11/83 I could try building a base system for people to play with.

I looked after eight DSM-11 systems for ten years (3x 11/70, 1x 11/44, 2x 11/84 and an 11/83 - the one I have at home now). I've probably forgotten most of what I knew back then but I can still find my way around a system. I loved Mumps as a language - breaks just about every rule of well behaved languages but so powerful with the integrated database handling.
