6 pen lie detector/EEG machine/Siesmograph/chart recorder

Very large chart recorder with extra wide 56 cms moving paper & 6 pens. The generic name for an instrument like this is a chart recorder but it could be used for depicting a period multi channel EEG machine or any other situation requiring the display of varying electrical signals in the form of mechanical movement of inked pens.

However this is presently not practical. The coloured wiggly lines are simply drawn on the paper by hand.
