a pair of HP-80 calculators
Two versions of the Hewlett Packard 80 financial calculator. Both with their metal boxes showing the two versions - with and without "80" on the front label.
The HP-80 was HP's second hand-held calculator ever produced, as well as their first financial calculator.
It came packaged in a very well made metal box, in contrast to the moulded plastic that the HP-35 scientific calculator came in at the time.
Introduced in 1973 and discontinued in 1978 - price at the time was US$395.
