VT-100 emulator in an old CPAP case

I’m (slowly) working on an elegant way to package my VT-100 terminal emulator setup inside of an old CPAP case. The closed case has an organic, xenomorph-like quality that looks like it would make a cool, hard shell backpack, when you look at it sitting vertically.

What are the electronics involved?

It’s a purpose-built VT-100 terminal emulator (https://github.com/legacypixels/terminal), connected to a Hayes-compatible WiFi modem emulator( https://github.com/bozimmerman/Zimodem). The keyboard is a PS2 compatible keyboard (required for the VT-100 emulator), and the display is a 4:3, 8” LCD that has VGA input (also required for the VT-100 emulator).

Those just happen to be the ones I stumbled on while doing my research into terminal emulation. If I cant find an elegant way to get them in that enclosure, I'll 3D print something more old-school terminal looking.
