It was alreay obsolete when I started working on it in '75. We actually spent a couple of weeks in class learning it, and by the time I was done, I was converted to RPN. The HP-65 was too expensive for a poor frosh back then, but when I finally got to borrow a friend's HP-67, I was delighted to find that I didn't even need to crack open the Owner's Manual. It turns out that those old desktop HP calculators are remarkably similar in function to the early handheld programmables. You should be able to program your 9100A just fine without a manual, if you just think pre-HP41 RPN. You actually have an advantage over the handhelds, in that you get to see the x, y & z registers directly. As far as parts go, I think you're sunk. Most of that stuff disappeared in employee auctions years ago. HOWEVER, someone at HP may have some old magnetic cards still floating around. Enjoy your toy. Ray
