as undergraduate in the 60s, the univ would shutdown the datacenter from 8am sat until 8am monday ... and let me have the whole place to myself ... initially 709/1401 ... and in transition to 360, the 1401 was replaced by 360/30 ... and then both 709 and 360/30 replaced by 360/67 (mostly ran as 360/65). after having been up for 48hrs, it was sometimes difficult to deal with monday classes. old post with "Real Programmers" tome http://www.garlic.com/~lynn/2002e.html#39 one of the items: Real Programmers never work 9 to 5. If any real programmers are around at 9am, it's because they were up all night. ... snip ... mentions getting complaints about tracking mud in halls of ibm san jose research (from cleats in hiking boots) ... path that I walked to work turned to mud when it rained. slightly different "Real Programmers" version http://www.garlic.com/~lynn/2001e.html#31 as bonus, also has "Real Software Engineers". past post http://www.garlic.com/~lynn/94.html#18 while the 360/67 mostly ran as 360/65, I did get to play a little with cp67 on the weekend ... has part of share presentation that I did fall of '68 ... references some performance measures from having re-written a lot of the cp67 kernel http://en.wikipedia.org/wiki/CP/CMS The above mentions initial cp67 release May 1968 ... however, three people from the science center came out last week of jan1968 to install cp67 at the univ ... and then I was invited to spring 1968 share meeting in houston for announcement ... I had already started to rewrite a lot of the code by that time. I also took apart os/360 stage2 sysgen and re-arranged order of all the cards to carefully place datasets and pds members for optimal arm seek motion (pds member ordering also minimized multi-track pds directory search) ... getting almost three times throughput improvement for univ. student job workload. -- virtualization experience starting Jan1968, online at home since Mar1970 ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
