A fellow technician once asked me : " If I wire 2 x 9v batteries in
parallel , will I get 4.5v or 18v ? "
My reply - a resigned " Oh , f*** off " didn't answer his question but
everyone else in the room was laughing anyway.
We also had an ex- RAF guy who used to ask for a 250v fuse - not a 12v one
, a 250v one !?
It took a long time to put him straight.
Both could be classed as "board jockeys " as opposed to their earlier
counterparts " valve jockeys".
I am also told of production workers on a TV assy. line who complained that
their remote controls didn't work.
Of course , they tested fine....etc. It turned out ( this was in the early
days of remote controls ) that they had "lifted " the remotes to use at home
on their old "non-rc" tv's.
Who was it said that ,to earlier civilisations, high technology would appear
to be magic ?
Not that much earlier , it would appear.
