Thinkpad keyboard to USB

It's technically the next day since its like 2am right now. I've spent way to much time on this project. Anyways, I think I've got a really good PCB layout, though I cannot figure out how to wire/route it. I am actually so awful at wiring PCBs it's actually not funny. I'll try and get the auto-router to do it, but I don't think it cant figure out the vias. Maybe when the sun is up I'll get my friend (who actually knows what he's doing) to help me out.

My time looks much lower because hacktime wasn't tracking because I use wayland. I SWEAR I SPENT LIKE 6 HOURS ON THIS:
I started with the main johnson. The Teensy 4.0. It's a beast for its size, and good for what I'm doing. I wired in USB D+/D− lines from the connector on the left (J6), passing through a protection diode (D12), V from USB routed to the Teensy’s VIN pin (via J6 as well), and a reset circuit with a 100K pull-up on the reset line (R11) and 2.2 µF cap (C1).

For power distribution and don’t-talk-to-each-other circuitry I used 0.1 µF decoupling caps (C3–C6) near VCC pins and 2.2 µF caps (C1, C2) for big energy social distancing. Also capacitors too.

The keyboard connector (J4, AA01B-S040) takes all the row/col lines straight to GPIOs. I tried to keep it neat. GPIOs 0–31 cover the matrix, plus pull-ups where needed.

TrackPoint was a bit trickier. It uses a 3.3V PS/2-style interface. The Teensy runs at 3.3V logic, and so does the TrackPoint, but I wasn’t 100% sure at first. To be safe, I added four BSS138 MOSFETs (Q1–Q4) with pull-up resistors (R3–R10) to handle level shifting between the TrackPoint clock/data lines and the Teensy. It’s probably overkill, but it doesn’t hurt. There’s also a header (J10) to break out the TrackPoint lines for debugging.

J2 is a soft power switch connected to a GPIO, and R1/R2 (715 Ω) are current-limiting resistors for the indicator LEDs.

Anyways, It's been like 6 hours of research and making this, and I'm ready to hit the sack. I'll work on the PCB tomorrow.

A little backstory:
I’ve always wanted to build one of those cyberdeck-y computers. the ones you see on reddit, crammed into a Pelican case. Problem is, most of the cool ones either skimp on the keyboard or use a generic 60% board. That’s fine for typing… if you’re a minimalist. But I need arrow keys, function keys, a proper Esc key, short enough keys to close the lid, while still being full size, and preferably something that doesn’t require me to lug around a mouse. If only there was a perfect keyboard with all those feats... Well there is! It is on the thinkpad T61. It’s compact, clicky, has a built in TrackPoint (the little red nipple thing you can use for a mouse), and it’s probably the best laptop keyboard ever made. One problem. It doesnt use USB. It uses some arcane ribbon cable protocol only Lenovo/IBM’s old motherboards understand.
