The midseventies SHARE survey 75

os-360 had another kind of failure mode .. the 1052-7 used as operator consoles on most 360 machines ... and if the 1052-7 ran out of paper, an intervention required would be presented to the system. os-360 when it got an intervention required would ring the system bell (load) and stop (the system bell could also be rung for various other reasons ... so it wasn't absolutely determinable what the problem was).

there was a little finger paper sensor that would sense when the end of paper occured ... now normally when that happen, the paper under the type head would be pulled out and last of the fan-fold paper fell to the floor (or possibly stand) ... so it would be pretty evident that you had run out of paper.

however, it was possible for the paper to stick just a little and not be pulled out ... so it wouldn't be evident why the system had hung ... at least not until great frustration (after trying everything else) ... you smashed you fist into the keyboard ... breaking the keyboard ... but also jostling the paper enuf so that it fell loose to the floor and it was now evident what the problem was. At this point the 1052-7 was also broken and a CE had to be called in to repair it.
