On a similar vein, I am aware of X Window(s) server
for the VESA API for VGA
boards. Most all VGA boards adhere to the VESA standard and provides quite
a bit of portability although performance is generally fairly low. Would it
be possible/feasible to create a VESA API for a NEC uPD7220A video board?
Generally, it's easier (with the book) to simply port the X server to
the real hardware interface instead of trying to emulate another
interface.
At the N8VEM home brew computing project we already
have a NEC uPD7220A
board that works and has been debugged. However creating software for it
has proven to be problematic.
I believe the places where I've seen the 7220 used was in a terminal.
I can't recall specific models off the top of my head.
