re: http://www.garlic.com/~lynn/2011g.html#73 We list every company in the world that has a mainframe computer i think escon was knocking around POK from the late 70s ... just took a long time to leak out ... in part because many uses would cross datacenter walls ... and communication group "owned" everything that crossed the datacenter walls ... and they thot high-speed was 56kbits; my wife had numerious battles with communication group over such details when she did a stint in POK in charge of loosely-coupled architecture ... misc. past posts http://www.garlic.com/~lynn/submain.html#shareddata Early 80s, there was enormous amount of dark-fiber (i.e. not yet lit) going in all over the place. When new Almaden research bldg opened in the mid-80s, telco put something like six fiber bundles into Almaden bldg. one of rs6000 engineers (in conjunction with rochester) had taken the original escon spec, tweaked to be about ten-percent faster, full-duplex, commodity, more reliable drivers and it was released as SLA. Then in early 90s, we talked him out of doing 800mbit version ... instead to work in fiber-channel-standard (group we had been working with for few years ... had come out of some work originally at LLNL). This became fiber-channel standand. Then some of the POK channel engineers caused a lot of turmoil by layering some unnatural half-duplex stuff on top of base fiber channel standard for FICON (I still have a bunch of old fiber channel standards mailing list from the period). passing reference about jan92 meeting in Ellison's office http://www.garlic.com/~lynn/95.html#13 In HSDT, I was doing a bunch of stuff ... including having custom stuff built on the other side of the pacific. misc. old HSDT email http://www.garlic.com/~lynn/lhwemail.html#hsdt and past posts http://www.garlic.com/~lynn/subnetwork.html#hsdt friday before a trip across the pacific early spring '85, communication group announced a new online discussion group on high-speed with the following definitions: low speed: <9.6kbits medium-speed: 19.2kbits high speed: 56kbits very high speed: T1 monday morning on wall of conference room on the other side of pacific: low speed: <20mbits medium speed: 100mbits high-speed: 200-300mbits very high speed: 500-600mbits old '89 email with copy of the spring '85 announcement http://www.garlic.com/~lynn/2011c.html#890731 notice that internal network and nearly whole internal corporation ran on vm370 back then ... misc. past posts http://www.garlic.com/~lynn/subnetwork.html#internalnet -- 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
