Hi, I'm trying to do something with some old monitors I have 
around.

I have 2 HGC (Old Hercules PC board) monochrome monitors and 
a couple of VGA ones and I would like to know how to deal 
with them with a microcontroller.

I've seen around some open circuits to deal with them with 
FPGAs and or Logic Gates.  I've also read about the MC6545 
and similar circuits.

What I would like to know or to read about is the timings 
and how they should be handled in order to make them work. 
I've read here and there without any clear scheme or timing 
graph.  Can anyone point me a link, book, pdf or something 
related in this direction?

I know I need a fast device, I think a dspic 33F will be 
enough for the Hercules Interface and for a VGA in 320x200 mode.

My goal is to replace the monocrhome Graphic LCDs a more 
specific and 'bigger' screen.

Thanks in advance
Mauricio
