CQ-1 most definitely, CQ-81 however...

But I agree, likely not the CQ series... so that leaves the classic Casio designation for Scientific's the "FX" series. Assuming the FX-50xP and FX-80 were the first (and yellow) Scientific LCD's by Casio (I think) this leaves the period 1981/1982 for an LCD Scientific with time - when the FX-60xP/FX-81 were launched, can't think of anything offhand. Interesting if there was.

I'm far from a Casio expert. However given your school period I'm about a decade ahead (late 80's/early 90's) in reasonable recall (although I live in Edinburgh!).

If the LCD was "yellow" that would date the Casio from '77(possibly)/'78 to '79/'80 however, but Casio produced relatively few LCD devices in that time period and after '80 all were of the more conventional variety. Before '79 I think most were that fluorescent blue thingy (nice by the way).

I really need to look more into Casio Calculator history ))
