Musings and comments about our common interest
We are in the final stages of writing a book on HP41 repair. We expect to have it finished by the end of September. In our experience you do not need to have any electronics knowledge to repair 80% of HP41's damages. The nature of many of these is either mechanic or bad connections due to corrosion. The focus of this book is on that 80%. It is written for those of you that wouldn't dare to repair your calculator before!
Here are some of the chapters:
The target price will be 9,99€ for the kindle version a 2-3 € more for the print version, and will be sold through amazon.com and on this website. I'll keep you posted through this channel. Do not hesitate to bring suggestions for additional content!
