Backus, 82, Fortran developer, dies there was some article blaiming us (at least in part) for the clone controller business. lots of past posts mentioning clone controllers http://www.garlic.com/~lynn/subtopic.html#360pcm all the references I've seen regarding redoing C & UNIX for portability make mention of (later) interdata machines (again 360-like) The First Unix Port http://www.usenix.org/publications/library/proceedings/usenix98/invited_talks/miller.ps Version 6 Unix - Wikipedia, the free encyclopedia http://en.wikipedia.org/wiki/Version_6_Unix Interdata_v6 http://minnie.tuhs.org/UnixTree/Interdata_v6/ Anecdotes http://doi.ieeecomputersociety.org/10.1109/MAHC.1989.10025 The Daemon, the GNU and the Penguin - Chapter 2 and 3 http://www.icims.csl.uiuc.edu/~lheal/doc/dgp/chapter02_03.html of course these machines were quite a bit after interdata/3 Interdata 7/32 and 8/32 http://en.wikipedia.org/wiki/Interdata_7/32 in the above ... references to perkin-elmer having bought interdata and quite a bit of success in "defense and aerospace" industries. people i've talked to since, have said that a lot of the sales involved attaching to ibm mainframe ... and the channel attach board didn't appear to have been redesigned since our original (still wire-wrap). Interdata Simulator Configuration http://simh.trailing-edge.com/interdata.html from above: Interdata was founded in the mid 1960's. It produced a family of 16b minicomputers loosely modeled on the IBM 360 architecture. Microprogramming allowed a steady increase in the functionality of successive models. * Interdata 3 * Interdata 4 (autoload, floating point) * Interdata 5 (list processing, microcoded automatic I/O channel) * Interdata 70, 74, 80 * Interdata 6/16, 7/16 * Interdata 8/16, 8/16e (double precision floating point, extended memory) In the early 1970's, Interdata was purchased by Perkin-Elmer. In 1974, it introduced one of the first 32b minicomputers, the 7/32. Several generations of 32b systems followed: * Interdata 7/32 * Interdata 8/32 * Perkin-Elmer 3205, 3210, 3220 * Perkin-Elmer 3250 Interdata was spun out of Perkin-Elmer as Concurrent Computer Corporation. ---------------------------------------------------------------------- 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
