Create a VAX CPU with FPGA?

[Curt at Atari Museum]

I personally would rather see some more hobbyist work on PCI Qbus and/or 
Unibus cards, the current commercial ones run $2500-$3000 and it would 
be GREAT to run SimH and have access to all the drives, tape systems and 
so forth directly with something more like $250-$500 vs the $2500-$3000 
cards.
