RE: Finally the rare (unobtainable) manual for Sharp EL-506P
I recently got both the EL-506A & EL-546. One thing that I've noticed is that the EL-546 seems to use a reddish solar cell while the EL-506SLR uses a brownish one; not sure if that makes any difference though (this calculator works well even under indoor lighting). Maybe the EL-506SLR is a newer version? The EL-546 seems to be stuck with 1973 CODATA values for the constants (not the 1986 ones unfortunately despite being a 1987 calculator).

My Sharp EL-546 (BTW is there any way to create thumbnails or spoiler tags so my images don't take up so much space?).

The EL-506A and EL-546 seem to be pretty much the same (except the constants and the solar panel). One difference I noticed was that my EL-506A can't solve 2-variable linear equations (only 3-variable), giving an error while the EL-546 has no problem with either 2 or 3 variable linear equations.

@Didier Lachieze You don't happen to have the manual for the EL-506SLR do you? Big Grin

EDIT: giubin, will the EL-506A you will be recieving come with a manual? If it doesn't it might help me motivate myself to scan in the EL-506A manuals if someone else is after it (I doubt it will be anywhere near as good as your one, but it might be usable at least).
