   That's awfully expensive SRAM, though.  A couple 62256 chips would be 
much, much cheaper and pull a WHOLE lot less power.

   I really don't see a VAX implementation happening in just one FPGA, 
unless it's one of the very large ones...and the very large ones cost 
thousands of dollars per chip.  One FPGA per subsystem or something 
would be more reasonable.

   But this is WAY off-topic.
