RSX-11

I've been e-mailing with someone and they have clarified that, yes, Mentec's correspondance/actions indicate that SIMH is still covered by the "Supnik license" even though it isn't a DEC product). Pity that there isn't an explanation on the SIMH website, but I suppose that Mentec doesn't want to throw money at explanations, and nobody else wants to pontificate in an "official" manner given the current state of the USA.

Sort of a precursor to the Internet? I remember Datel advertising on TV about making stock market transactions in your office. The model 33 was not the most popular device for that environment.

RSX-11

My question, however, was regarding the non-commercial PDP-11 stuff. At this point, I'm not interested in the commercial stuff- it just isn't worth it. (before you grab the torches and pitchforks I don't find Windows "worth it" enough to walk across campus and pick up the all-but-free disks either). I was looking into emulators (never touched the VAX's little brother or O/S SW yet), and came across some disk images with the following licensing: "Whereas, MENTEC owns the rights to the following PDP-11 Operating Systems and associated layered products (RT-11 V5.3 or prior, RSTS/E V9.6 or prior, RSX-11M V4.3 or prior, RSX-11M PLUS V3.0 or prior) (SOFTWARE TECHNOLOGY) and is prepared to grant a non-exclusive license to use such SOFTWARE TECHNOLOGY for personal, non-commercial purposes;" and "SOFTWARE TECHNOLOGY shall mean the binary versions of the PDP-11 Operating Systems (RT-11 V5.3 or prior, RSTS/E V9.6 or prior, RSX-11M V4.3 or prior, RSX-11M PLUS V3.0 or prior), and associated utilities and layered products that run on PDP-11 computers. " but somewhat cryptically also "EMULATOR shall mean software owned by Digital Equipment Corporation that emulates the operation of a PDP-11 processor and allows PDP-11 programs and operating systems to run on non-PDP-11 systems. 2 LICENSE GRANT MENTEC grants to CUSTOMER a worldwide, non-exclusive, royalty-free license under MENTEC's INTELLECTUAL PROPERTY RIGHTS to use and copy the SOFTWARE TECHNOLOGY solely for personal, non-commercial uses in conjunction with the EMULATOR." So, in short, is this only valid for emulators in which DEC or it's successors in interest (HP?) own the copyright, or is it only valid for systems where DEC or (...) hold RTU licenses for a PDP-11 emulator on? If the prior, what is the connection to SIMH? If it is valid for currently obtainable emulators and (as it seems to at face value) include RSX-11, why no RSX-11 images? I suppose RSTS/E is the easy way out, (provided licensing is good), but RSX-11 has the advantages of some commonality with VMS (DCL).

PDP8/E schematics

> So, who knows what documents I need and where to get them? Clean copies of 8/E schematics are difficult to find. I'll go through the scans that I have to try to find a good set. Most of the omnibus interface schems are on line under http://bitsavers.org/pdf/dec/pdp8/omnibus

Big pile of VAX documentation to be disposed

by jzg22＠drexel.edu

There is a large pile of VAX and other documentation waiting for disposal on the 7th floor of Disque Hall at Drexel University in Philadelphia. Disque hall is located on the former 32nd street between market and chestnut streets, its the tall(~10 floors)) brick building. Pretty much everything paper, and a working Phaser 370? printer (missing its paper tray and missing the centronics->microcentronics adapter but otherwise working) is free for the taking. This documentation originally went along with the VAX machine which someone from the list rescued from there about 2 years ago when it was being disposed. Jonathan Gevaryahu jzg22 at drexel.edu
