My recent acquisitions seem to have fallen into the
category of
handheld calculators and are as follows:
Casio fx7000G - Seems to be the first graphics handheld, and was
introduced in 1985 at 70 UK pounds. Operates on three 2032
lithium cells. No external power offered.
ISTR that those were standard equipment in schools around 1990 (for A-level
courses). They were quite good machines, but pretty slow. Someone wrote a
Mandelbrot program for them; it would take several hours to render and almost
exhaust a set of batteries.
I've still got a 7700 which IIRC was the 7000's bigger brother. Still works and
gets used quite often, although I run it off a 9V alkaline battery (not sure
what prices are like elsewhere, but those 2032 lithium batteries are horribly
expensive over here)
cheers
