Internally, IBM was putting so many distributed 4300s out in departmental conference rooms that conference rooms became a scarce commodity. The big explosion in distributed 4300s also attracted the MVS group, they had the problem was that the only disks for non-datacenter were FBA and MVS never bothered with FBA support. Eventually they did come out with 3375, CKD simulated on FBA3370 ... however it didn't do much good, the distributed environment requirement was also for scores of 4300 systems per support person ... while MVS required scores of support people per system. some old 4300 email http://www.garlic.com/~lynn/lhwemail.html#4341 I also got sucked into doing early benchmarks (on engineering 4341) for LLNL that was looking at getting 70 for computer farm ... leading edge of the coming cluster supercomputers. single 4341 benchmarked faster than 370/158 and 3031 (in addition to clusters having better throughput and price/performance than 3033). past posts mentioning "RAIN" benchmark (objective was that it run approx. as fast as CDC6600) http://www.garlic.com/~lynn/2000d.html#0 Is a VAX a mainframe? http://www.garlic.com/~lynn/2001d.html#67 Pentium 4 Prefetch engine? http://www.garlic.com/~lynn/2002b.html#0 Microcode? http://www.garlic.com/~lynn/2002e.html#75 Computers in Science Fiction http://www.garlic.com/~lynn/2002i.html#7 CDC6600 - just how powerful a machine was it? http://www.garlic.com/~lynn/2002i.html#12 CDC6600 - just how powerful a machine was it? http://www.garlic.com/~lynn/2002i.html#19 CDC6600 - just how powerful a machine was it? http://www.garlic.com/~lynn/2002i.html#22 CDC6600 - just how powerful a machine was it? http://www.garlic.com/~lynn/2002k.html#4 misc. old benchmarks (4331 & 11/750) http://www.garlic.com/~lynn/2003g.html#68 IBM zSeries in HPC http://www.garlic.com/~lynn/2005m.html#25 IBM's mini computers--lack thereof http://www.garlic.com/~lynn/2006x.html#31 The Future of CPUs: What's After Multi-Core? http://www.garlic.com/~lynn/2006y.html#21 moving on http://www.garlic.com/~lynn/2007d.html#62 Cycles per ASM instruction http://www.garlic.com/~lynn/2009d.html#54 mainframe performance http://www.garlic.com/~lynn/2009l.html#67 ACP, One of the Oldest Open Source Apps http://www.garlic.com/~lynn/2009r.html#37 While watching Biography about Bill Gates on CNBC last Night http://www.garlic.com/~lynn/2011c.html#65 Comparing YOUR Computer with Supercomputers of the Past http://www.garlic.com/~lynn/2011d.html#40 IBM Watson's Ancestors: A Look at Supercomputers of the Past http://www.garlic.com/~lynn/2012n.html#45 Under what circumstances would it be a mistake to migrate applications/workload off the mainframe? http://www.garlic.com/~lynn/2013.html#38 DEC/PDP minicomputers for business in 1968? http://www.garlic.com/~lynn/2013c.html#53 What Makes an Architecture Bizarre? http://www.garlic.com/~lynn/2014c.html#61 I Must Have Been Dreaming (36-bit word needed for ballistics?) http://www.garlic.com/~lynn/2014j.html#37 History--computer performance comparison chart http://www.garlic.com/~lynn/2015h.html#71 Miniskirts and mainframes http://www.garlic.com/~lynn/2015h.html#106 DOS descendant still lives was Re: slight reprieve on the z http://www.garlic.com/~lynn/2016e.html#116 How the internet was invented http://www.garlic.com/~lynn/2016h.html#44 Resurrected!
