- Build a new sync separator to get the vertical sync from the GBS-8100
- Rebuild the keyboard as a USB keyboard and use keycaps that closely
match the originals. (this will cost the most $$$ and so will probably
be done last
- Put in a Raspberry Pi
- Get everything working on a single power supply and board. This will
require voltage regulators and some standoffs, but I believe it would
be well-worth it in the end
