[rescue] Microcontrollers and terminals

With the talk about microcontroller-powered terminals, I figured I'd look 
at this again.  I have two boards and built one.  The one I built one and 
wasn't that impressed.  What I really want is something that can produce 
full color VGA and perhaps SVGA.  What I've seen so far only does 
monochrome VGA.  This would allow more fun with ReGIS and Sixel graphics. 
The big trick seems to be that most microcontrollers seem incapable of 
bitbanging full color.  I don't see anything promising on Mouser or 
Digikey for VGA chips, so it looks like getting
https://opencores.org/projects/vga_lcd/ into silicon is the best approach.
