IBM Model M advice needed

Just found a keyboard for free it was mine from over 20 years ago, trying to modify it and making it look right with the arduino teensy hid inside. Any ideas on going from SDL to teensy inside the keyboard? Or I found on similar models where you could solder on a couple of 4.7k resistors to make it functional with normal PS2. Does anyone know what points those resistors need to be soldered to?

Unless you're going to a PS/2 motherboard, it's simpler to just get a PS/2->USB converter (e.g. bluecube).
The resistor thing shouldn't be needed on a true PS/2 board, but fyi:

What year is that keyboard? Pretty sure that particular PCB isn't one we see a lot of.

its an 84 brought the PCB to work with me so I could desolder the old 6 pin connector, I ordered another arduino to put in the middle so I can keep the original chord. Going to go from pcb->teensy->old connector through some jury rigged glory.

Think it should be closer to early 90's.

Sticker on the bottom says 84. Not sure if its like a shakespeare fishing real from the 30's where the 1960 number on them was actually the model number but it seems unlikely,

They all say 1984 on the printed label. The born date is something different.
