Image of inside of HP71B HP-IL module

[pamphonica]

I have a pretty clearly damaged HP-IL module and would like to see what the contact area should look like. If anyone has a working 82401A HP-IL module and would be prepared to lift off the metal cover and take a few close-up photos I would be very grateful indeed. I think there may have been small metal fingers on the pads, but all that is left is a roughened solder surface, and two pads are missing but have no obvious traces to them. The main calculator just has a set of flat edge-connector-style pads.
My module does not appear to the host HP71B so there is almost certainly a contact problem, at the very least.
It seems a real shame to just junk this module as it might be persuaded to work again.
All help gladly received.
