Origin of the term minicomputer (was Re: PDP-1 as minicomputer

Certainly not. It's clearly closely related to the HP9810, HP9820 and HP9821 calculators Ther HP9810 is a 3-level stack RPN calculator, designed to replace the 9100. It displays all 3 stack levels on 7-segment LED displays, with a similar digit size ot those used in early HP handheld machines (they are not quite the same dispalys, the pin bending is different IIRC). The HP9920 is an algerbraic-notation calculator with a 1 line 16 character alphanumeric display Both these machines use magnetic cards for storage and have a built-in card reader. And space for an optional thermal printer (that seems to be almost always ftited). They only have the simple functions (+,-,*,/,sqrt IIRC, but are user-programamble. There are optional ROM modules to add other functions -- the 'maths' ROM, adding SIN/COS/TAN, etc is farily common. As I mentioned in another message, the 9830 is a BASIC-programmed computer/ It uses tape cassettes for storage, and has a built-in interface for the 9866 thermal printer (there is no internal printer). The HP9821 -- the only model in the range that I don't own (and in fact have never seen) is essentally an HP9820 with a tape drive rather than the card reader. It can take the internal thermal printer IRIC. All these machines use the same bit-serial 16 bit processor board set with the same microcode/ So I think they're closely related. -tony
