Yes, LCM had just the console. I left UCLA and moved to CDC land at UW-Seattle in '78. I don't know what happened to, or replaced, the 360/91. The main machine room at LCM was impressive. At one time I had used all the (types of) machines in it. Dave On 9/13/24 8:21 PM, Mark Huffstutter v

This was from the 360/91 at UCLA when I was there in the 1970s. I recall seeing them working on refurbishing it when I was last at the LCM a few years ago. On 9/10/24 4:50 PM, Fred Cisin via cctalk wrote: On Tue, 10 Sep 2024, Paul Koning wrote: And perhaps craziest of all, $189k for a 360/91

The US Letter size of folded Versatec paper came in a cardboard box that was really good for compartmentalizing small stuff and stacking for storage!  I used to scrounge around the waste containers for empty, used boxes. Still have many in use. Dave On 4/13/24 11:40 PM, Tony Duell via cctalk

I visited CHM in early 2018. I actually didn't go to CHM proper, but arranged with them to visit a warehouse nearby where they store a lot of stuff they don't display. I was able to see my "first personal computer" circa 1962. It was an IBM 709, the last vacuum tube computer from IBM (I thin

Washington State Ferries still use 50 cent pieces and 2 dollar bills a lot. After years of receiving them as change, I finally asked why? The reason is they reduce the number of hand movements by one half. If you're sitting in a kiosk all day dolling out change, it can reduce repetitive wris

Are you sure the referenced early PDP-11/10 wasn't really the PDP-11/15? We got an 11/15 because it was cheaper and DEC had one sitting around that we could get with end of year left over budget funds. On 12/21/18 2:00 PM, Bill Degnan via cctalk wrote: On Fri, Dec 21, 2018 at 4:47 PM Jay Jaeg

The sources to each release were usually included with the distribution so that custom system settings could be sysgened. The sources are uncommented, however. You could implement this by finding the commented out source in the sources and regenerating the system, with the code in the appropr
