Interesting side note: On the HP-35 doing x^y the display goes blank for a split second, but on the HP-80 doing y^x causes the display to flicker as if it is running a program. I have to wonder if the HP-80 was programmed differently in order to pack so many functions (programs actually) into it.

I know I know, so simulators :-)

Just curious though, the simulators returned the same results

The HP35 took 1720 instructions to process so about 1/2 second display off time assuming 800KHz clock.

The HP80, HP70 leave the display on for calculations because they can take a lot of time to process some financial problems. That way the user knows it is busy.
The HP80 took 1546 instructions to process and the HP67 took 1632.

Tony, thanks for enlightening me on why this function operates differently on the HP-80 from the HP-35. I have both actual calculators, so it's fun to see the differences. I've also downloaded your simulators for the 70 & 80, and I am very impressed. Yes, they operate just like the originals.
