I'm pretty sure University College, London (UCL) had a 360/195 on the net in the late 1970s. I remember it had open login to I guess it was TSO? I'd play with it but couldn't really figure out anything interesting to do lacking all documentation and by and large motivation other than it was kind of cool in like 1978 to be typing at a computer in London even if it was just saying "do something or go away!" I guess you had to be there. -Barry Shein The World | bzs () TheWorld com | http://www.TheWorld.com Purveyors to the Trade | Voice: 800-THE-WRLD | Dial-Up: US, PR, Canada Software Tool & Die | Public Access Internet | SINCE 1989 *oo* On January 26, 2015 at 03:36 barney () databus com (Barney Wolff) wrote:

I seem to remember a 195 as well but maybe it is just CRS.Google says the 360/195 did exist. But my baby was the 360/95, where the first megabyte of memory was flat-film at 60ns, which made it faster than the 195 for some things. It was incredibly expensive to build - we heard rumors of $30 million in 1967 dollars, and sold to NASA at a huge loss, which is why there were only two built. I used to amuse myself by climbing into the flats memory cabinet, and was amused again some years later when I could have ingested a megabyte without harm. Ours sat directly above Tom's Restaurant, of Seinfeld fame. Very early climate modeling was done on that machine, along with a lot of astrophysics.
