It was "officially" announced at the spring 68 SHARE meeting in houston. besides traditional customer dataprocessing installations ... there were some number of commercial online timesharing services built on cp67 and the later vm370 available on 370s http://www.garlic.com/~lynn/subtopic.html#timeshare one of these services providing commercial online timesharing services with vm370 was Tymshare. Tymshare opened a version of their online conferencing system to SHARE as VMSHARE in aug76. Archives are here: http://vm.marist.edu/~vmshare/ The science center was also responsible for the networking technology used for majority of the internal network ... which was larger than the internet/arpanet from just about the beginning until approx. mid-85 http://www.garlic.com/~lynn/subnetwork.html#internalnet various old email mentioning the internal network http://www.garlic.com/~lynn/lhwemail.html#vnet The same technology was used for the educational bitnet (& earn in europe) ... was in the early 80s was approx. the same size as arpanet/internet http://www.garlic.com/~lynn/subnetwork.html#bitnet One of the largest (virtual machine) online commercial timesharing services was the internal HONE system. http://www.garlic.com/~lynn/subtopic.html#hone initially after the 23jun69 unbundling announcement http://www.garlic.com/~lynn/subtopic.html#unbundle there was concern that new system engineers had last much of their learning avenue. prior to unbundling announcements, new system engineers gained much of their experience in somewhat as apprentice as part of vendor teams onsite at customer locations. after unbundling, system engineering time at customer locations was charged for ... and charging for "apprentice" system engineers wasn't justified. HONE (hands-on network experience) systems were initially setup for branch office system engineers to gain experience using operating systems running in (initiall cp67) virtual machines. The science center had also ported apl\360 to cp67 for cms\apl ... and a lot of cms\apl tools were developed. Internally there were a large number of sales and marketing tools developed and were also starting to be deployed on HONE systems. Eventually this use came to dominate all HONE activity ... and running guest operating systems in virtual machines pretty much disappeared. Eventually customers orders couldn't even be processed w/o first having been processed by HONE applications ... and HONE systems were replicated around the world. >From just about the beginning, until approx. the mid-80s ... i provided highly modified cp67 kernels ... and later vm370 kernels for numerous internal locations ... including HONE operations. some old email mentioning transition from cp67 to vm370 http://www.garlic.com/~lynn/lhwemail.html#731212 http://www.garlic.com/~lynn/lhwemail.html#750102 http://www.garlic.com/~lynn/lhwemail.html#750430 I also did some amount of early computer conferencing on the internal network as well as working with external customers ... including Tymshare. At one point, a procedure was established where i would obtain monthly copies from tymshare of all the vmshare information ... which i would make available internally ... some old email mentioning vmshare http://www.garlic.com/~lynn/lhwemail.html#vmshare including making copies available on hone systems ... some old email mentioning HONE http://www.garlic.com/~lynn/lhwemtial.html#hone for other topic drift ... recent post mentioning internal computer conferencing like activity from over 25yrs ago http://www.garlic.com/~lynn/2008g.html#47 My last post in this forum ---------------------------------------------------------------------- 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
