I can't find a picture right now. Anyway, it appears these cables aren't available anymore. But there are at least two solutions around, one by Katie and another by Harald:

You can find more information in the "Not quite HP Calculators - but related" subforum:

Katie's solution uses the first of Harald's boards and the second solution by Harald involves installing a board inside the calculator. There are, however, numerous solutions in the "Not Quite" forum ranging from simple to exotic and cables occasionally turn up on eBay or in the Classifieds.
