PDP-11 Operating Systems

DSM-11 is Digital Standard MUMPS for the PDP-11. It's effectively a multiuser database with a programming language; the implementation is persistent sparse arrays. The original MUMPS language was developed on the PDP-7 and ported to numerous machines. DSM is also available for VAX, although it is not included in the hobbyist PAK set. :-( MUMPS was not just a programming language but an operating environment sitting on bare metal. We have an RL pack that's labeled DSM-11 but I haven't yet cleaned it up and mounted it. -- Ian ________________________________________ From: cctalk-bounces at classiccmp.org [cctalk-bounces at classiccmp.org] On Behalf Of Wolfgang Eichberger [oe5ewl at gmail.com] Sent: Friday, March 11, 2011 3:01 AM To: cctalk at classiccmp.org Subject: PDP-11 Operating Systems Hi everyone, You may have noticed in the pdp11 usenet groups that over some time I have collected a nice bunch of PPD-11 OSes in various versions (this takes less space, I have to deal with some kind of space restrictions at the moment). From time to time I tend to put online what I have found (please see 5ewl.blogspot.com if you want). There are some well known archives out there in the internet, but some OSes mentioned in the PDP-11 faq and other sources are kinda hiding from me. Let's start here: As I was reading the Ersatz-11 documentation file I stumbled upon "Fox 2/30 OS". Does anyone now something about this OS? Did any copies of this system or documentation and software survive? The only reference I have found so far since I read the Ersatz-11 docs is here: http://archive.computerhistory.org/resources/text/Foxboro/Foxboro.Fox... (can't look at this file at the moment as I am on a slooooow internet connection). All I found out is there's a strong focus on process control in this system as well at it should be some kind of OEM. Another OS I am currently looking for is CAPS-11. It is mentioned at some points, but I could find almost no documentation, definately no sources or tape images. Much of the other OSes I've got in my little list are missing the early versions. It would be a pleasure to see these showing up somewhere and making them available for the interested Enthusiasts. I saw discussions about licensing and property issues about some other OSes too (like DSM). They seem to be stucked at some point, hopefully these OSes don't get lost sometime. Here's a little sum-up about Systems I didn't came across so far: CAPS-11, CTS-300 and -500, DSM-11, DURESS, GAMMA-11, HT-11, MERTS, Micropower Pascal, MONECS, MTS, PC-11, RUST/XM, SPHERE, TRAX If you have any information about the Operating Systems mentioned in this message or can help out with disk images, disks, sources etc. I'd greatly appreciate if you'd drop a line.
