I have a casio ex word dictionary that has a broken flex ribbon cable. Is
there anywhere that I could possibly source a replacement. The connection on
each end is the same, and I could live with something that will just work
rather than the original cable. I think there are 28 pins on the end but it
is rather difficult to count. The spacing is the same as if you lined 30
gauge wire side by side.

That's not much help to non-americans. 'Gauge' i.e. AWG is a US only measure.
The rest of the world uses mm.

Can you measure the pitch properly ?
