IBM 122-F ES to US ANSI - Lot of pictures

[idollar]

Hello,

• Here there is a link to a similar post of my IBM AT that I posted before
• Here there is a link tp a similar post on my IBM 1390120.

This will eventually be a post with lot of pictures of this restoration and transformation process.

Tips/Findings in this threadp

• The ANSI conversion can be done. But we already knew that thanks to foat. Refer to the original guide. This is just a copy.
• joc discovered that the numberpad of a 122F can be transformed in a 4x5 matrix. Refer to this post. Thank you joc !

The photo tools:

• D800 + nikkor 35mm 1.4 ... very nice body and even nicer lens. One can get easily addicted.
• Debian. I still have not found a reason for using something different.
• Darktable. A tool that changed my live.

Regarding copywrite of the pictures:

• Use them. Enjoy them. Sell them. Do whatever you want with them.
  If any sells at $6.5M, share it with me, please:-)

1.- Tribute to the original layout

I can only start this post with a tribute to the this keyboard as it was during the last 28+ years.
Somehow I feel like I have betrayed it by doing this transformation, but on the other hand it was also requested from a long epoch without any use. This transformation will give it a new live that I hope that it will enjoy as much as I expect.

Thus, following pictures of its original status, once cleaned and rust removed.

6.- Taking the board apart and Board Stickers

The contrast in one of the pictures is extremely forced. It was not possbile to see the text. Big thanks here to Darktable !

7.- The Foam and Plate

As you can see, some barrels were glued to the foam, which broke it.
I had to repair it. Check the following section 8

[quote="idollar" post_id=205751]8.- Foam Repair

I did not want to change the complete foam just for the broken part. I wanted to keep the board mechanics as close as possible to the original. So I decided to patch it.

I normally use two layers of the foam that I have. I used only one to keep at the right thickness. The broken part got an extra layer, two in total.

Converter

18.- Software

I am using TMK modified to light LEDs as per this post.

You can find a push request in GIT also here.
Which works but Hasu decided not to integrate with this code

I do not use Soarer's solution as it is not Free Software.

this is good idollar, I´m looking forward to your pictures!

[andrewjoy]

that F122 case is in amazing condition

[seebart]

hmm interesting how my IBM 1389278 looks different, mine has a beige plastic bottom case.

ah I see the picture at 3.- Case and Birth Date:

Wow, idollar, these are some excellent photos. Really very detailed, thorough and well-composed. I originally thought that this was a 122-key Model M, but now I see that I'm mistaken - now I'm even more impressed!

Thanks for the words

Good point. This thread may deserv a correct title

[idollar]

I hope that the title is better now. The number of chars in the title is too short for my taste

Awesome pictures! You should stick some of these on the wiki somewhere.

Awesome pictures! You should stick some of these on the wiki somewhere.

Actually, after the first post (IBM AT), I asked myself if the forum was the right tool to use. I am not trying to document the restoration but to share some pictures with people that may be thinking in taking apart their keyboards.

If anyone thinks that this should go in the wiki, I will not have any problem to add it. My only problem is the time that processing this amount of information takes.

The quality of these pictures is amazing. The whole process can hardly be documented any better.
