Talk:Burroughs MCP

message: Copies of substantially the same article exist in several locations including Fact Archive; many of those sites cite Wikipedia as the source, so it is difficult to tell now if this is a copyvio.  Someone better equipped to research the history may want to have a closer look. --Kgf0 19:08, 3 October 2005 (UTC)

message: I'm proposing to move this page to the name "MCP (Operating System)" because no one calls it the Master Control Program.  I'm not sure how many people know that that's what it stands for.  As I understand it, the only way to make it show up on the Category: Operating systems page as MCP is to change the name of the page.  I won't move it for four days to give anyone who wants to a chance to comment (and because as a new user I can't use the move command for four days anyway).--JeffW 04:36, 14 February 2006 (UTC)
thread_title:  Moving page to MCP (Operating System) 

message: I worked as a Burroughs systems programmer in the 80s and had a B6700 and B6800. At least then, and I imagine still, all of the source code for all the systems programs was available and in fact that was how you did MCP and other component patches and upgrades, i.e. recompilation. There was/is no reason to protect the sources because they only run on the B machines.

: In fact, because I was quite young as Systems Programmer I printed out all of the MCP and most of the other base OS elements
:: Signing and correcting,just received some correspondence on it. Dunno when I posted this, but I did confirm later that Unisys still ships source, I think in the '08/09 timeframe . Lycurgus (talk) 11:01, 26 August 2015 (UTC)
thread_title:  Open Source? 

message: I'm not sure I buy the claim that MCP was the first open-source OS. In particular, IBSYS was available in open source on the IBM 7090, introduced in 1959, and it descended in part from an OS developed by SHARE members on the 709. Further, it was not common for operating systems code to be shipped in binary only form in that era; that practice did not start until the late 1970s in the IBM world, and it was hardly unique in that regard.

thread_title:  First open source OS? 

message: "Unlike IBM, which faced hardware competition after the departure of Gene Amdahl, Burroughs software was designed to run only on proprietary hardware."
I suspect, but offer no evidence, that IBM software was designed to run only on proprietary systems, i.e., IBM's S/360 architecture.   Unfortunately for them, Mr. Amdahl designed compatible hardware.
If someone had bothered to build Burroughs-compatible hardware, presumably Burroughs software would be equally 'portable'.
That is, this is not a matter of software design; it is a matter of whether there were functional clones of the original hardware.  — Preceding unsigned comment added by 108.20.148.80 (talk) 02:23, 4 February 2016 (UTC)
