Google search found 'St Bernadette' school who 'monitor staff' (8-)#
ie found nothing on the web.
Any more details like model ID?

I think it very very very very unlikely it is a straight through
connector - there are too many permutations.
Sinclair was the sort of guy who specialised in making apparently std
sockets, non-standard - ie 9D serial connector.
Sticking wires in pins could be dodgy. Find the GND pin first using
continuity meter (with power off). I will stop here - I reckon it would
be pretty dodgy trying at random. Is there no existing lead? At least
then you can see active connections.
