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

Jules
