IBM Model F AT Modifications
« on: Fri, 05 July 2019, 16:57:34 »
I finished modifying my Model F AT today, so I figured I would share some pictures. I started taking pictures a lot later in the process, but I assume most of you reading this all know what a dirty IBM Model F AT looks like, and what it looks like on the inside. I'm just sharing some of the things I did that I haven't seen in other posts.

After cleaning the keyboard and spray painting the barrel plate with black rustoleum, I ordered a pro micro controller off ebay, along with some other miscellaneous things.

I took photos with my phone, they aren't the greatest.

I soldered and shrink wrapped the controller.

I got and modified a panel mount USB-B to micro USB cable, and got it to fit between the screwholes.
222244-1
222248-2

I was able to make the inside area above the keyboard clean and tight fitting.
222246-3

I came up with a cleaner way to stabilize the spacebar.
222252-4
222254-5

I had to trim the spots between the ctrl and alt key locations.
222256-6
222258-7

I decided to use model m keys, because they are easier to change around without disturbing the floss I put into each spring.

Nice work! I personally wouldn't do the numpad that way, but you did a great job.

I will study that space bar stabilizer before I do my next one.

"We are on the precipice of signing an agreement to advance talks with Iran that preserves the good parts of former President Barack Obama’s Joint Comprehensive Plan of Action (JCPOA) while amplifying its flaws.
Mr. Obama came to an agreement that did not involve America’s most precious treasure, the lives and limbs of our soldiers.  The 1.7 billion dollars of frozen Iranian assets released by Obama pales in comparison to the 300 billion being floated as a rebuilding fund.
So far, speculation that Iran will be free in the future to continue its nuclear program is the opposite of Trump’s stated goal for the war and in direct opposition to what Mr. Obama negotiated."

Yeah, I use the numpad and arrow keys a lot, and I wanted the Ins, Del, Home and End cluster to be easily typable.

As for the spacebar, It works great, however I filed down a bit too much so it wobbles a little bit up and down.

I get where you're coming from on the nav keys, but I simply removed a bunch of keys, attempting to get as close to an SSK as I could:

Tried a few variations. 

Interesting spacebar stabilizer trick.

I need to figure out how to do all this. Which guides did you follow? And where did you source your materials for the most part?
