The only HP handheld calculators that used magnetic card programing were: HP-65 - Introduced in 1973 at $800 HP-67 - Introduced in 1976 at $450, replaced the HP-65 HP-41C-series with card-reader option (1979) The HP-45 came out in 1973 for $400, and HP dropped the price of the HP-35 to $300. The HP-45 was HP's second and more capable scientific calculator. It was not programmable. >Prices were outlandish in those days ( late 50's and early 60's) >for a young engineer. I'd imagine so...since that time span was 10 to 15 years before the first HP handheld appeared. The HP-35 wasn't marketed until Spring 1972. HP's first scientific desktop was the HP-9100, introduced in 1968 for several thousand dollars, depending on options. 73, Mike / KK5F (Self-admitted calculator geek) _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
