Reminds me of my first, professional, programming job. The Motorcycle dealer
where I worked had an HP-?? (I forget which, but it had a magnetic strip reader for programming) and I managed to fit a Payroll Tax Calculation system on one card. Long after I quit that job, I'd get the calculator and the new tax rate tables in the mail with a check every year, and reprogram the new tables. Many waters under that bridge<G>. Probably we are talking about 1976 or so. Yes, performing calculation on a non-RPN calculator is still very difficult. I can't imagine why RPN isn't standard - It's so intuitive. My dad bought an HP-35 ($395 in the early 1970's) and I've been an RPN kinda guy ever since. Dan / WG4S / K2 #2456 <snip> My boss here was looking for a good RPN calculator and figured he might find that one on eBay cheap. </snip> _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

If the strip reader was built in you had the HP-65. Later the HP-41
(31?) series had a strip reader as and optional plug on unit. I used the HP-IL to RS232 converter with my HP41.
