For which models was 2^3>8?

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.
