I'm using the one with the two blue buttons - reset and erase - and it is very fast to flash using my RS232-serial-to-usb converter cable. (...) I used Walter's manual's instructions. Never failed to work; I even had two very old and very used batteries in one of the calculators. I set my port parameters to my standard 8-1-N 9600 auto-handshake.

I had no problems doing the overlays except that the key-labels stuck to my tiny screwdriver and my tiny tweeters (...)

Thanks for sharing your knowledge and results on your HP-30B/WP-34S, Sikuq!

As I started my professional life as an electronics engineer, I've decided to build the serial cable myself (just for fun) instead of buying one. Maybe this is a mistake, we will see. I will post the results as soon as the Chinese suppliers can deliver the components that I have ordered 3 weeks ago...
