RE: HP97 The journey begins
Back again,
Things are moving faster than I thought. I have completely stripped the 97 down except for the card reader. Except from some dirt and dust inside, its pretty clean. A few problems I found were due to age mixed with mishandling of circuit boards. I have seen these bent pins on a few boards and I think it is caused by being in a hurry and not checking placement when re-connecting the boards. Depending on the pin, if undetected, it might lead one to think the board has chip problems. The other problem is one where someone has handled the boards with dirty or sweaty fingers and has caused the corrosion. It's a bit hard to see in the image, but the finger prints really stand out on the blackened areas. It all still works, so hopefully just a spring clean. Card reader next... cheers Tony |
