It won't start, so I can't check.
Does it have its serial number written on the back? If so, enter this >>>> in <https://checkcoverage.apple.com/?locale=en_GB> and it will show the
model
Update:
I've managed to start it. I sprayed some switch cleaner into the
Magsafe connector and the next time I connected it, the little green >>> light came on. I pressed the power button and it burst into life.
It is MacBook 3,1 (2GHz Intel Core2 Duo).
OK. That's really quite old and will require people to remember what OS X
was capable of back then.
[...]
The MacBook sounds old (how did you remove the battery???)
I turned the coin-slotted button a quarter of a turn, which released the
battery compartment lid with the battery attached.
[...]
Progress:
I've now connected my own projector to the MacBook with the adaptor,
which adapts the rectangular Mac connector to (I think) VGA. Using
QuickTime I can display a picture from the camera without recording it
and set it to full screen to give higher definition.
System Preferences > Screen gives many options for the video output,
so I ought to be able to find something suitable when I try it on the
hall projector tomorrow evening.
If the hall projector can cope with the 75 Hz frame rate from the
PowerBook, I could put the slide show on the bigger screen and keep the smaller one for the enlarged view of the apparatus. My experience of
modern projectors is that they offer huge range of pixel definition
formats but hardly any frame rate options.
I've now investigated the projection facilities at the hall. The
connection to the projector is a type I have never seen before and for
which I have no adaptors or leads. It is on a box screwed to the wall
at one side of the hall and nowhere near the position I want to place
the demonstration apparatus and camera.

Can you take a photo of this connector and compare it with what you find
on the web?
Does the hall provide a technical specification that would show the type
of connector and signals required?

I shan't be in the hall now until the actual presentation next week, so
it would serve no practical purpose.

None that I know of, it's just a village hall.
