  The MMI 32R16 "super pal" may be a bit slower than a 16L8 (Tpd of 40 ns
max) but to compare it with a 16L8 I think is unfair.  To quote the spec
sheet of the 32R16:
   The PAL/32R16 is a synchronous state-machine that implements the familiar
state equation, Y := F(X,Y) where Y, the state vector, "is replaced by" on
the rising edge of the clock, a Boolean function, F, of Y and the input vector
X.
  It has 16 SMAC's which stand for State Machine Atomic Cell which consists
of a registered sum of products with feedback forming a one-bit state machine.
  The 32R16 features product term sharing between output pairs, programmable
output polarity and register preload.  Registers can be bypassed in banks of
eight leaving combinatorial outputs.  There are two separate clock pins for
independent clocking of register banks.

  End quote.

  From this it seems to me to be a very flexible and potentially powerful
PAL.
