Mainframe upgrade done with wire cutters (2010)
Post by h***@bbs.cpcn.com IBM obviously "lost money" in giving out free software; I don't think they charged even for distribution tapes or documentation even in the 1970s after unbundling; if it was a legacy free item, you got the package for free. (And IIRC, some unbundled fee products were still quite cheap, esp as compared to today's software prices.) Anyway, the free software was IBM's 'loss leader' to build the utility value of its computers.
Not quite an upgrade, but anyway a modification.I was employed in a company which used an IBM 3780 (RJE terminal)The capacity was too limited, so the comapny invested in a local(Regnecentralen) equivalent, basically a DG Nova with Documation cardreaderand a DataProducts lineprinter.Now the problem was, that the CPU, was a 24 bit machine, which not quite canaccomomdate a 80-column card image, as 80 is not a multiple of 3. "wire" or "jumper".But what color do you paint the tolerance band?Omit it - 20% is good enough.Best answer yet!--Roland HutchinsonHe calls himself "the Garden State's leading violist da gamba,"... comparable to being ruler of an exceptionally small duchy.--Newark (NJ) Star Ledger ( http://tinyurl.com/RolandIsNJ ) But when it came down to a major expenditure,like repaving, we knocked that out real fast.I think it was in the book _Parkenson's Law_ where a wonderful example ofthis was given: corporate management might spend hours discussing where toinstall bicycle racks for the employees, but go through the approval processfor the purchase of a nuclear reactor in just a few minutes.
