16-bit only, but thank you for offering, I appreciate it.

It certainly would be, considering that it's impossible :-)  CGA and VGA 
both have adapter RAM at B800:0000.  You can still do dual-monitor, but 
it would have to be Mono/Herc and CGA or Mono/Herc and VGA.  Mono/Herc 
has RAM at B000:0000 and doesn't overlap.  Many debuggers support this

You can't put VGA into a Tandy 1000 because the Tandy video cannot be 
disabled, IIRC.  There were a few Tandy 1000 models that had VGA 
onboard, but while they supported Tandy 3-voice sound+DAC, they did not 
support Tandy 16-color graphics.
