If they are identical to the ones I'm thinking of, they have a notch
at the back. This notch of off-center. It enables you to test whether
your are accessing side A or side B.
I've used them extensively in Philips equipment, but they were also
used by Facit and others.
The capacity is 250k bytes per side, and the format is called ECMA34
Good luck
