Thank you all for the infos. Didn't really know the details of HT-11
and GAMMA-11. Both would be nice findings (at least for historical

MINITS sounds interesting too, I'll start my recherches. Do you have
any details Phil?

Regards, Wolfgang

ps: I hope you'll see some progress soon Dan!

>> 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.
>> Have a good start into the weekend,
