Can anyone help please?
25d Fool represented zero as one in a friendly chat SH?O?Z?R (not certain of the "H") Only word that fits is shnowzer -form of schnauzer??? Have I gone wrong somewhere?
21d A milking machine, one working at last T?P??? (I know this clue pairs up with 26a and their endings have to be switched to fit in the grid - 26a is drop in I think!)
