Now for the fun part. Opened it up, depopulated the motherboard, hacked off the left half of it to make room for new components and checked what sort of stuff might fit inside now.

Putting the hacksaw back in computer hacking.

Now onto the keyboard conversion. made an opening where the old CPU was in the mainboard, attached a pin header for a Teensy LC, and wired the keyboard's ribbon headers to it.

A bit messy on the wire routing, but it works a treat! Still plenty of room on the protoboard to fit up other hardware as needed. I followed the same procedure as I did for the teletype keyboard conversion, and it was time to settle on what hardware to run in the cyberdeck....
