Default Re: Equipment Identification Help.

This is, as it says on the serial plate, a Rank Bush Murphy MR773 Mk 4 monochrome 625 line tv picture monitor from I would say, at a guess, the late 60s or early 70s

This monitor accepted two composite video inputs (switchable) and a single (optional) external sync input

All inputs were ‘loop through’ allowing signals to be extended to other equipment if required (or terminated in 75ohms if not)

This was the standard configuration for analogue video

Hope that this clarifies a little bit - sorry but further info has not survived in my ‘archive´ ��
