IBM 107 FMK - IBM 107 472X-41-53951 - Lot of pictures

[idollar]

Hello,

I was working with the keyboard yesterday. I have taken some mesurements that I will post hopefully after work today
If someone is interested in mesuring any specific part, tell me. I will post it.

I have added new sections and pictures. Let me know your comments.
If you have interest on seeing something special, ask for it!

[LLRnR]

Your photos are really wonderful!

Just a quick question, for wet sanding, do you use a special tool or can you just use sand paper and a sponge (between your palm and the sand paper)? I'm planning to sand the back plate of my SSK, which is a bit rusty.

Thanks for the appreciation. It is nice to read that my effort is appreciated.

Regarding the sanding is as simple as having a glass with water near by. I cut a small piece of sand paper and put it for no more than two seconds in the water. Then I sand gently, without pressing too much.
If your plate is rusty you may want to press more.

If your target is a SSK back plate, you can search for a post with my results on the same part. (I will look for it for you, give me a second)

Your PCB has quite a bit of holes in it. The PCB on my F107 only had two, one for each indexing pin on the bottom plate.

There is the post that I mentioned

The PCB that I am reparing is having 3 holes.
The back plastic cover between the PCB and the back plate was missing. I made one. This will come in future posts.

Hey, you are right. I did not notice the extra holes !

Thanks for the info and for the link. I already have some sandpaper, quite different grits. Now I just need to find a free and calm weekend to bolt-mod my SSK and sand the plate.

Looking forward to see the rest of your restoration process!

Then you should check the new chapter that I just posted: the new foam.
More will follow in a minute

I forgot to pictures to the new section 9. I have added them

[idollar]

and a section 10 ...

(EDIT: Never mind, there's too much anticipation on my part (with reference to the reason for removing the old controller). I'll let your log follow and only ask questions only if I don't understand what it is that you're doing.)

You may ask anything at any time !
I was busy with something else. I will post some new pictures now

Added sections 11, 12, 13 and 14

This is amazing! I need to make time to restore mine.

Brilliant documentation! You should pursue a career in science ...

One of many photos that cry "DT header":


Is it only the lighing or did you use a tilt shift filter?

Perhaps when I grow up.

Is it only the lighing or did you use a tilt shift filter?

It is just the lighting. Exposure of some 20sec. Very low and soft light. F22 if I remember correctly.
It is not rocket science

This is really inspiring. My project for this summer (when I have some space to breathe, I'm finishing my Master's degree now) is to acquire, restore and adapt a Model F AT. From what I see, it seems xwhatsit is the way to go for Fs and beamsprings. Did you get yours from OHS Park?

Enough for today.
If I cut an additonal picture my brain will explode

An AT will not require an xwhatsit. A converter will do. It is cheaper and you will keep the keyboard as it was originaly build.
Check the first post. You will find a link to a "lot of pictures" that I did for an AT

I received the xwhatsit together with my first 107. The restoration that you see is my second keyboard. I like it so much that I got one for the office and a second one for home.

As I recall, Soarer originally wrote his firmware to be able to re-map his AT.

@LLRnR

And your proposed name is ... ?

Hehe, it's not hard to figure why it is that you like it so much!

What I plan to do for the AT is to remap a lot of keys on the AT. I can see it working as a great layout, just not in its original state. In this case, if a xwhatsit is not required, the better for me, as it's easier and cheaper to buy Teensies than xwhatsit's.

As I recall, Soarer originally wrote his firmware to be able to re-map his AT.

In the meantime, there's a new confirmation from fohat.

Great, so if it's just the AT, a Teensy with Soarer's, a soldering iron and a lot of guts that I need, that'll do Thanks for the hints, guys!

@LLRnR

Ohh hmmm... I found i(HAVE0)$ to be very funny! I'm not that good with names, though, lemme think... in any case, it should be something recalling the sheer mass of metal on this beautiful beast, now tamed.

EDIT: I know! Hulk!

[idollar]

Upss, I missed you post. I added to the list

[idollar]

For those that do not know how this thread works: the interesting bit is at the beginning of the thread (first page). The first post contain the pictures.

it's just the AT, a Teensy with Soarer's, a soldering iron

Depending on how good you are at the workbench, this

is what you really want to do.

Hi,

As you know, the restoration is not finished, but since the beginning of the week I am using this keyboard at the office to test the feeling of the raw metal.
Yesterday I got a little electric shock from the keyboard. In the morning and in the afternoon.
Today, wearing different shoes, I got another one.

I thought that it was worth reporting to check if someone else had the same problem or it is only liked to the direct touch with the metal. In my opinion and from the safety point of view, it should not make a difference to have it painted or not. The design should be resilient to this.

It could well be that the earthing is not well done. I will check it and report. I do not have the required tools with me (nor the required time to do it now)

Cheers.

I think I've stumbled upon this some while ago. Thanks for the link, it's an excellent thread and the spacebar mod is just amazing.

After everything you've done for her, this is how she repays you!...

I hope it's just the grounding and that it can be easily fixed. Good luck!
