The Boca SVGA board is available locally at a reasonable price.
I've seen it mentioned here so thought I'd ask a few questions, 
mostly directed to people who have this board:

1) The board has only one 14.? MHz crystal on it.  How does it generate
   the different clocks required?  I assume it uses a VCO or something.
   Is this an acceptable way of doing things?

2) The manual says it supports 800x600 at 60Hz.  This seems a little low
   to me.  Is there any way to speed this up to 70Hz?  It also supports
   1024x768 at 60Hz but I couldn't afford a screen to do justice to anything
   faster anyways.

3) It has the tseng 4000 chip on it.  Can I assume its compatible with
   s/w which uses the 4000 (in particular Roell's X386 under ISC)?

4) Is the board reasonably fast?  Especially compared to other tseng 4000
   boards (STB, speedSTAR, ...)?

5) Can anyone send me CLOCK.EXE from X386?
