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.

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.
