I tried the HP Museum benchmark https://www.hpmuseum.org/speed.htm

This entails running the program for 60 seconds, then using R/S and inspecting a storage register for the number of completed loops in the 60 seconds.

I found occasionally that the calculator would turn off when pressing R/S, and now after many tests it seems that running the program for 60 seconds is fine, R/S stops the execution. However running for 61 seconds or more leads to the R/S button both stopping execution AND turning the calculator OFF.

Turning back on and all is normal.

Sometimes I also see that R/S has no effect until pressed a second time, but I can't find a pattern.

I do find that using this benchmark your firmware is somewhat faster than the stock DM15L firmware!

Stock V32_m1b firmware at 48MHz : 676 loops complete
LF15C_beta240916 firmware : 1346 loops complete
