I just got a 1976 book about calculators:
"Calculators Users Guide and Dictionary", by Charles J. Sippl. Matrix Publishers,1976.
Has descriptions of calculators manufactured by Adler, Burroughs, Canon, Casio, Biolator, Chromerics, Commodore, Compucorp, Fondilifier, Hanimex, HP, IBM, Litronix, Lloyds, Master specialties, Melcor, Monroe, Mostek, Olivetti, Olympia, Optel, National Semiconductor, Ricoh, Rockwell, Sharp, Sinclair, Tektronix, Telesensory, TI, Time computer inc, Underwood, Unitrex, Victor, Wang.
HPs described are: 65,25,21,35,45,22,80,81,
Introduction says: "Calculator industry specialists estimate that another 50 to 70 million calculators will be sold to North Americans from mid-1976 to mid-1978. The rate of sales jumped from a few million per year in the early 1970s to about 20 million in 1975. Exports of japanese calculators to the US in December 1975 alone totalled 1,550,521, according to the Japanese Finance Ministry. The japanese shipments to the US for 1975 totalled 11,074,779 (of the 32 million Japan and Far East produced). The US produces and sells about 7 to 9 million, the majority of them being the more expensive or high-end of the market. The retail prices of all units range from $5 to $10,000 - from shirt pocket simple arithmetic units to vey large calculator systems with pratically all the power, peripheral and versatility of medium-to-large computer-communications systems. Users range from 5-and-6-years-olds to atomic and space scientists and pratically everybody in between.".
My intention is to keep it - I think it is a "photograph" of 1976 situation. Anyway, if anybody is keen of books like this, I would trade it for some HP related stuff.
