It's _really_ hard to figure out which parts of this are quoted and which parts are replies...

Ah, I guess that second paragraph is the new bit? Good to know, thanks. (Although I've seen elevators refurbished, usually because the old one broke. Usually just the control circuitry, not the plumbing, but it's the control circuitry that handles this. Still, old gear still in use. Got it.) Rob P.S. I may have a slightly skewed opinion of this stuff because as a teenager I was in an elevator (at either the Frankin and Marshall or Farleigh Dickinson campus of CTY) that tried to go up a floor higher than the building it was in had, and banged against its top end stop a half-dozen times before opening the doors and letting us out. Happily, we didn't plummet to our deaths. Years later there was the hydraulic elevator at (the year 2?) Penguicon hotel that worked fine under normal load but by noon each day of the convention it had overheated to the point the hydraulic fluid leaked through the seals and then it gradually lost the ability to go to the higher floors (and got slower and slower going up) until it could only go between the ground and second floors and then got an "out of order" sign on it until it had cooled down again. But I didn't ride in that one because it was out of order every time I tried, we all just took the stairs, the building was only like 4 stories...) _______________________________________________ Toybox mailing list Toybox@lists.landley.net http://lists.landley.net/listinfo.cgi/toybox-landley.net
