While I am waiting for my upgrade processor to arrive, I got to wondering: Does the HP-45 emulation allow one to access the HP-45 timer function?

Since I never had the courage to perform the crystal installation, my HP-45 remains a stock unit. I can access the undocumented timer function by pressing RCL and then pressing CHS and 7 and 8 simultaneously.

Does this work on your multi-calculator upgrade when the HP-45 is selected?

Thanks!

Yes, it does work. Tony has implemented it. Timer mode is entered by pressing rcl enter.
The timers have better accuracy than on most unmodified HP 45s,
but they are not perfect. They are off by a few seconds per hour.
