I saw that the listing is available on PDF. Unfortunately, the Adobe reader in my computer is broken. I will try to get to the library tomorrow and see if I can dump it there. I do have a working HP-67 thanks to repair by Viktor.
I hit a documentation jackpot at a rummage sale today. Got an HP-25 which has a problem, an 83033A Battery Pack for the HP-97, four HP-67/97 Users' Library Solutions (Control Systems, Energy Conservation, Thermal and Transport Science, COGO Surveying), three HP-67/97 card pacs with documentation (Standard, ME Pac I, Cvil Engineering Pac 1), an HP-97 Owner's Handbook and Programming Guide and a bunch of HP-41 material, all for three dollars.
Two days before that I got a Tandy 200 (successor to the Model 100) for $2.50 and two working calculators not listed in the Ball/Flamm book for twenty-five cents each. A good week for collecting!
The HP-25 comes on OK. I can change display modes, write programs, and enter numbers from the keyboard. I can STO and RCL. But doing any mathematical functions from the keyboard or in a program, even the decimal point, end up with 0.000000000 in the display and a changed display mode. Any ideas?
