I bigger yell was heard at Tandy in 1981, where I saw a noobie engineer try
to put a 4:1 Bishop taped layout (it was on D size gridded Mylar) into the
∗blueprint machine∗ to make a copy. The ammonia made the tape delaminate off
the mylar onto the pinch rollers. We lost the layout (it was for a
stand-alone print spooler....remember those?) and the blueprint machine cost
$3000 to fix it.
