Notes on my VS4k motherboard
-----
Issues:
- No FB card
  - lack of S3 switch needs workaround (see below) to use serial consone
  - maybe why serial BREAK doesn't HALT
  - maybe why DZ test fails
- Fails DZ interrupt test (0x50) most of the time. No explanation.
- Stinky and still a little dirty
- NVR/TOY clock module battery is dead

- Keyboard doesn't work by default
  - add "i8042.reset i8042.nomux" to KCL in grub on install and on first boot
  - add above to 
- GPU works with Prime... 
  - Install nVidia proprietary
  - Try "sudo ubuntu-drivers autoinstall" - especially on Kubuntu which has a broken Software Manager proprietary drivers tab
  - Set up Prime for ondemand
  - When running a command that should use the GPU, prefix with:
    "__NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia"
- "Howdy" works for IR cam login

GOALS
- To make a handheld emulator for the historic Altair 8800 that recreates the feel of having blinkenlights
- To learn about FPGA development
ARCHITECTURE
- Hardware:
  - Business card size PCB
    - All components except pushbuttons on the board top
    - LEDs are backfiring and shine through holes in the PCB
    - 4 pushbuttons, heavily multiplexed for front panel control
    - PCB is to be made matte black to mimic panel-mount LED look
