Talk:MCP: Difference between revisions

Thus, 35 years after being systems programmer at Daytona Beach Community College (now Daytona State), I now have hands on a current MCP (18) system <span style="background-color: black; color: lime;"><ref><font size=1  color=black> At DBCC, the SPO for the 6700 was in my office, it and the production 6800 had between them less than 2 MWord of RAM and there was not much more than 1GB of disk, if that. The MCP XE I run has 2X the processors, 32X the RAM and about 20X the disk. Mill is harder to judge, but i5 3.3GHZ is about 50X times the 150ns B6800 clock, and it does about 83K MIPS vs presumed less than 10 MIPS for the B6xx. The i5 box was bought refurbished for about $100. The B6700 was gotten off a state of FL salvage depot but it probably used more than a $100 of electricity a month. The prod machine served 500 transaction types to several hundred terminals and the 6700 served a dev staff of about 10. During registration I sat at the production SPO tweaking system factors, before the dev machine came up I think.</font></ref></span> and that opens a role for the Unisys MCP in the DCP, where "Unisys MCP" will be used wherever the distinction needs to be made clear. Usages like ODT, DMS II or MARC unambiguously refer to the Unisys product line as we never intended taking more than inspiration from it.<span style="background-color: black; color: lime;"><ref><font size=1 color=black> "CANDE", "WFL", and "MCP" are the actual overloads, "SPO" isn't really used in the modern Unisys culture, it's been lost from the mainframe days, so the smalltalk thing I'm doing doesn't map to anything specific, although functionally MARC and the ODT would be the analogs. The original SPO was just an ODT with supervisor permissions. Whose thing, mine or Unisys that is referred to by the overloaded terms will be clear in context (within Unisys MCP or not) and use the same "Unisys" modifier where needed.</font></ref></span>Much of the base mainframe stuff is available in the Windows based product and updated for the current epoch, though obviously it's a limited version of the actual priced product that runs on their hardware.
