Not sure about the 10s but for the 10s+, they didn't use the fx-85MS "as a model", they used the fx-85MS itself. It's a Casio board inside the 10s+.

Casio have sold OEM boards for as long as I can remember. Even full OEM calculators with someone else's label on them.

Ah, okay. The 10s and s+ have several keys swapped around from the FX-82/85MS layout; arrow keys match the 48-family more closely; the x^3, a/b/c, square root and some other keys moved around, so there must have been some work done on the keyboard matrix at least for HP. The only other difference I can see for the 10s+ is a slightly different colour scheme. Under certain lights, I suspect that'll be harder to read the llight blue.

My only experience with the HP-10s was a bad model, as several lines of dots from the top line disappeared, otherwise I would have kept it, and it would have cost me more money to send back to the retailer for a refund.

The laugh is, I'd been prompted to buy the calculator because the listing showed 128kb of memory. Clearly most of that memory wasn't accessible for programming, and indeed the calculator isn't programmable. I have my doubts about whether the 128kb of memory figure was correct, even considering that some memory would have been set aside for statistics variables and regression calculations.
