MNT VA2000 graphics card in a Mega ST

[rpineau]

Hi Keli.
Very interesting stuff.
As you might know (or not), me and Juliusz have a 68020 board for STE/MSTE with an expansion bus.
I was planing on making a video card for it but looking at what you're doing may be we wont and instead support you :)
Of course our bus is 32 bits but totally supports 16 bit wide access. We can make the adapter from the VA2000 to our bus (looks fairly straightforward :) ).
In any case, great project and thanks for working on this.

Sounds interesting. I would recommend using something like the MiniSpartan 6 instead, and add the level converters on the adapter board instead of using the VA2000 due to some issues I've mentioned earlier. That would give more flexibility (and an extra HDMI port)

edit and adding support for a different bus could be added by swapping out the bus interface module on the HDL side... As long as there are free io ports.
