TERRA Operative:
Ha, you found the datasheet I translated from Japanese. :D

I sent an email to the Russian company a few posts above. Let's see if they reply otherwise I might need to see if a friendly European forum member can freight forward for me. :)

I feel your pain. I have an AS-A that had almost fully dried electrolytic capacitors on the power supply that may have damaged an IC or another. The calculator works moderately well for a few minutes and starts to become erratic. Also, division does not work at all, but that may or may not be related. These devices are quite difficult to source.

findchips.com seems a good place to start, never actually had to buy any, yet.
