it is not a 'wish list'-simply that the instructions do not exist...hence
several are required to make up for the inadequate design....
a 4004 or 8080 or 6800 or whatever---can all be used to the same
ends--with similar results---for me to prefer a normal c/zn battery
over a ni/cad is not logical--in terms of electrical preformance--
but in terms of toxicity,well...not at all 'holding my breath' for
adi to z80ize their chip...it is a workable product that can be
improved..like all products including the z80....dont know bout
you,but a full tool box is much better than only a blade screwdriver
and a pliers.
