Sitting in the cockpit last week on the way to Tokyo when the guy beside me pulled out a beat up 15C. Of course, I had to talk to him about it and pulled out my 71B, 42S and 15C.
Now I have to explain why I have 3 HP's in the flight bag:
1. 71B is a new toy that was just reconditioned and I was
converting all 42S RPN programs into basic.
2. 42S was a replacement for the 41CX, my favourite, because it
was not as buggy as the 41CX in the static environment of the
3. 15C because it fits in the pocket and is just fun to play with!
So, after examining his, I noticed his program memory was empty. I went ahead and a programmed it with 15 routines applicable to our specific job. Gave him my overlay card and program outline notes. He played with it for the next few hours and on the way home. He bought it new in the eighties and uses for simple stuff, and now the complicated stuff.
He asked me if there was a replacement and I mentioned the used market and the value for a good example. He was stunned. I asked him if he would by a new replacement if one was available. His answer was YES, probably 2.
So, there is a market, even for non collectors and HP museum attendees.
Myself, at least 2, backup and spare just because of the projected speed of the machine. Currently a Great Circle, and Intermediate latitude programs take 30 seconds of "Running" prior to display! The 42S takes about 2 seconds, and doing the comparison of the standard:
With 1's loaded in the stack on the newest 12C I would suggest the answers will be instantaneous if they do reissue the calculator based on the newest 12C platform.
Does that make me a horder? No.
