Thank you! let me just test this:

That was a bit cheeky of me considering how difficult and time consuming it is to do so, so ignore that request!

One thing though I'm quite curious about if you do have the manual somewhere is the power specifications of the calculator. I think I saw 50 lux in my internet travels (and it really does well under low light, nearly as well as the TI-34 so that seems about right), but it would be nice to know the actual power consumption like the EL-506A is 0.0002W for example.

I'm also wondering about the differences in panels between the models. Perhaps the EL-506SLR has a more efficient panel (Monocrystalline?), and could potentially run faster than the EL-546 which is why it had to be clocked down a little from the EL-506A to meet the same light requirements....it's all just speculation as I would need to see both side by side to test.

Hmmm, what about the constants, for example elementary charge ([CNST][9]):
1973: 1.6021892(46) x 10^-19
1986: 1.60217733(49) x 10^-19
EL-546: 1.6021892 x 10^-19 (1973 value)

Eddie (same person that posted in this thread I think) did a write up on this on his blog http://edspi31415.blogspot.com/2020/09/r...tific.html
It looks like those silver buttons as well!, now I'm wondering whether Eddie's version that he reviewed were grey buttons (hard to tell from the angle) or silver like the one you posted.

Yep, nice work around! (create a 3rd variable set to 1), thanks!
