Hi;
It has been a long while since I have been on this site. Lots of exciting things have been going on I see. Sad, what has been happening to hp. I really hope the ships Captain knows where he is sailing!
I am sure this question has been asked before, but does anyone know the size of the O rings that go in the card readers? I purchased my card reader for my 41C in 1990, and the O rings finally degraded or whatever they do. Motor runs, but card barely feeds. Sounds bogged down. I guess I am lucky the O rings have lasted this long. There is a shop not far from where I live that claims they carry or can get any O ring made. I would like to try the repair.
I had to go back to Using my 41 since my 49G+ keyboard malfunctions too much. I have to watch it like a hawk, as it types in too many digits on several keys. Never was able to get it repaired properly. I believe a ROM update was tried that was supposed to help, and it was sent back to hp once, the calculator returned with no change. It has been shelved. Too bad, as I rather liked that calculator aside from it's crazy keyboard.
I used a TI N-Spire CX-CAS the other day, wow! Lots of bells and whistles and I like the color screen! It looks like a really fine learning machine.
Be well and Thanks.
