Arrr they were the days. Ive come over all sentimental.
The machines had proper brake pads.
A service meant using oil and grease and proper tools (spanners etc).
Patient circuits lasted years and were cleaned in Cydex.

None of your read the DVM and if it is out of spc turn a screw until it is.
You had to know about proper engineering thingies. James May could do a programme on that. It would be realy interesting.
