The HP 67 and HP 41C programmable calculators were released 3 years apart and were very different. The HP 67 had a builtin card reader, no alpha capability and no continuous memory. The HP 41C was alphanumeric and had continuous memory and an optional card reader.
Despite the differences, HP used the same magnetic cards for both calculators and included functionality in the 41C card reader to read and translate programs from the HP 67.
Loading and executing the HP 67 Calendar Functions card day of week function is demonstrated for todays date on both calculators.
