I used to work with an IBM
System/3 and RPG II back between 1978 and 1980 at Hoffman la Roche in
Mijdrecht, the Netherlands.
On market day one of us would buy stroopwafels
and place them on top of the CPU to warm.
They'd be exactly the right
temperature at 3 o'clock in time for tea !
These where the good days during the 70's & 80's.
