Prime and Saturn calculators

That's very interesting! I wonder how deep the emulation goes - I would have thought it would need to emulate the 15 digit BCD to give the pretty much identical results, but I could be wrong about that.

So when the most recent Prime was introduced in 2018, it was using 31 year old code, now 37 years.

I see further down that second thread that someone mentions the HP-12c source code went missing. I wonder if that was before or after the HP-12c platinum, which shares some similarities to the original HP-12c, but seems to work on a 12 digit platform.
