Technical Notes

First, a disclaimer: beware of programmers who carry screwdrivers. I am a software guy. Although I know how to handle a soldering iron and have some burn marks on my hands to prove that I am no novice, my expertise lies mainly in programming computers, not building or fixing them. Take this into account when you read the articles below.

• A small (but growing) Knowledge Base
• Disassembly Instructions for Selected Models
• Battery Pack Repair
• Notes on Corrosion
• Repairing HP-67 Card Readers by Mike Davis
• Repairing HP-97 Card Readers by Mike Davis
