Despite this, the calculator came with a large program library. I have one of these in my drawer, it works, but due to inaccuracies, or rather, imprecision, it is little more than a collector's item.

Thanks for the hint! I just secured one off ebay UK
Would you happen to have the documentation for it? My example will come as the bare calculator.

Found all I was looking for on Katies website!
