I bought a IBM model F recently. The keyboard is dead. No function. Openning it I found the following:
The rest looks "fine" but since I have no knowledge of fixing this wonderful keyboard I would appreciate your help what to look for aside from this.
Tell me if you want other pics.
Thank you for your help.

Which model F is that? With the exception of the AT, none of them will attach to a modern PC without a converter or new controller.
Edit: looks like an AT. What are you connecting it to the computer with?

right I just remembered that myself, unfortunatley I don´t have a converter or new controller right now
This baby looks like this and the sticker on the back reads:
ID NO.515X-55-87113L
MODEL 000
PART NO. 6450200
DATE OF MFG 16-07-1985
MADE IN THE UNITED KINGDOM
but that part in my first pic looks bad. Any tips on replacing something like that?
I just connected it with an DIN > PS2 adapter.

It should work with just the DIN->PS/2 adapter. Are you sure it's plugged into the keyboard and not mouse port? I wouldn't worry too much about the original cable, that's just part of the shield sticking out.

I have it hooked up via a normal DIN->PS/2 adapter. The adapter is fine. I´m using it now with my Focus FK-2002 . Unfortunately the model F is not responding at all. I took it apart, looks fine except for the cable shield. Any ideas?

It would be good to test the continuity.

Can the conical part on the cable slide around?
If I recall correctly, the black rectangle and that conical part are supposed to be one plastic part functioning as strain relief. If it got so worn that it broke (for example if the cable was too tightly wound around the keyboard while in storage), the cable itself might have suffered some damage.
Can you take a multi-meter with built-in continuity tester and check if the cable is still fine?
EDIT: Seems I spent too long digging up pictures of the strain relief, Hypershere beat me to posting.
Here's a picture of that strain relief, found on http://www.epiguru.com/2012/04/model-f- ... sassembly/

not in my opinion, BUT I am not experienced in this, you guys take a look:Hm...do look any of the components look weird? Does something look burned or broken? Or the common bulging capacitors....
That´s some solid information in that link JBert, thanks for that !! I don´t have the tools for the continuity test now, it will have to wait.
Looks like this is gonna be a long-term project for me, I was hoping it would run "out of the box" but hell the keyboard is 29 years old!

Before I got a multimeter, I used to test continuity using a battery, light bulb, and a piece or two of wire.seebart wrote: ↑<snip>Hm...do look any of the components look weird? Does something look burned or broken? Or the common bulging capacitors....
