Finally I got my HP-67!

[Artur - Brasil]

Hi,

I apreciated very much the replies to my post and I believe all aproaches are good, as they preserve this part of computing history working!

But now I need some information about HP-67. Yesterday I openned my unit again to fix the card reader. Some wires just twisted on terminals, broken soldering and so on. Well, I fixed everything. The card reader is now giving sinals it is alive - not working properly yet.

But another more serious problem arose: the keyboard!
HP-67 can be completely dismantled and give access to all parts of keyboard, which is completely different of HP-11C, 15C, 41C, in which keyboard plate is melted on chassis.

Weel, hp-67 has some rectangular plates for contact, and covering it a very simple sheet of of very simple plastic. Is this correct?
HP-15C has an adhesive plastic, not an usual plastic, covering the plates (disc format), and one thiny sheet of rubber.

After closing my 67, the keys got loose. I tried other solutions, but none worked. Around 4hours trying and nothing.

Just behind HP-67 keys, there is a hole. There should be something between them and contacts?

Many thanks for your support!
