The problem is that very few people have both a grasp
on that knowledge
and
the ability to do the necessary electronic design - it's only really worth
it
for a drop-in replacement (i.e. a single chip or a very small
daughter-board
to plug into the ULA's 40-pin to DIP socket) because (as Phil says) it'd
be a
reasonably large board to do it as discrete logic.
This knowledge should be shared...One of the things I plan to do when I
learn VHDL is to create a "for dummies" tutorial. But, if someone knows how
to create a circuit using ttl gates, you can use one of the manufacturers'
tools to change it to vhdl/bitstream. I use an altera tool where I can enter
my design in schematics. All cpld/fpga manufacturers has this option.
