re: http://www.garlic.com/~lynn/2011e.html#45 junking CKD; was "Social Security Confronts IT Obsolescence" in the wake of FS demise ... there was mad rush to get stuff back into the 370 hardware & software product pipelines (there are claims that the distraction of FS allowed clone processors to gain market foothold) ... doing 303x (3031 was 158, 3032 was 168, 3033 started out 168 wiring/layout with faster chips) in parallel with 370/xa ... some discussion of FS, 303x, and 3081 http://www.jfsowa.com/computer/memo125.htm POK managed to convince corporate to kill vm370, shutdown the vm370 development group and move all the people to pok to support mvs/xa development (or otherwise mvs/xa wouldn't be able to meet ship schedule). Endicott managed to save vm370 product mission ... but had to reconstitute a development group from scratch. The shutdown strategy for the vm370 product group was to not inform them until the very last possible minute ... minimizing the number of people that might find something else. The information was leaked ... resulting in witch hunt to find the person responsible (extremely paranoid atmosphere in the bldg. during that period). There was joke about the head of POK was major contributor to vax/vms ... because so many of the development group went to work on vms. the MVM upthread historical reference: http://www.garlic.com/~lynn/2011d.html#73 has os/vs2 release 1 (SVS) plus delta for os/vs2 release 2 (MVS) on "glide path" to os/vs2 release 3 (FS). Also mentioned, simpson (from hasp, aka jes2) did RASP ... basically paged-mapped MFT. He then left, and was redoing RASP from scratch (in clean room), at Amdahl. as an aside ... one of the "nails" in the FS coffin was that if ACP (TPF) were run on FS machine built out of the fastest circuits then available (370/195) it would have the throughput of 370/145 ... 1/20 to 1/30 the thruput of eastern acp/SystemOne (on 370/195). misc. past posts mentioning ckd, fba, multi-track search http://www.garlic.com/~lynn/submain.html#dasd misc. past posts mentioning FS http://www.garlic.com/~lynn/submain.html#futuresys another FS reference: http://www.cs.clemson.edu/~mark/fs.html -- 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: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
