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.

"The Trump campaign announced in a letter that Republican candidates and committees are now expected to pay “a minimum of 5% of all fundraising solicitations to Trump National Committee JFC” for using his “name, image, and likeness in fundraising solicitations.”
“Any split that is higher than 5%,” the letter states, “will be seen favorably by the RNC and President Trump's campaign and is routinely reported to the highest levels of leadership within both organizations.”"

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?
