You could probably simplify things in terms of construction
tremendously by using FPGA or CPLD methods. The result should be no
more or less accurate to the original than the TTL version.
But that is what made it special - the components at the time.
They have 3 input NOR's in tiny logic, so do smaller PCB's
if you want a smaller system. :)
