                     14: .I Pal
                     15: reads data from the standard input or

                     17: in the form of
                     18: .IR minterm (10.5)
                     19: and writes on the standard output data suitable
                     20: for
                     21: .IR prom (10.1)
                     22: driving a PRO LOG programmer with a MMI PAL adapter.
                     23: .PP
                     24: The options are:
                     25: .TP
                     26: .B -x
                     27: Produce a table filled with '\-' (fuse blown) or 'X'
                     28: (fuse present) for checking by human being.
                     29: .TP
                     30: .B -d
                     31: Produce output suitable for use by
                     32: .IR drom (10.1)
                     33: driving a DATA I/O programmer with a LogicPak.
                     34: .PP
                     35: .I Pal
                     36: has internal tables that describe the fuse layout
                     37: and addressing inside the chips. The
                     38: .I type
                     39: flag on the command line is used to address the correct tables.
                     40: .I type
                     41: means the pal type, for example, "AM22V10".
                     42: .PP
                     43: The numeric symbol of a term that corresponds to the output
                     44: enable of a pin is 100 + pin_number by convention.  Just to be strange,
                     45: the convention for the 22V10 is: 200 + pin_number for polarity,
                     46: 300 + pin_number for architecture fuses and pins 25 and 26 are
                     47: asynchronous reset and synchronous preset respectively.
                     48: .PP
                     49: The pals with X in their name use an additional convention.
                     50: Since
                     51: .IR quine (10.1)
                     52: can only handle and-or logic, and the X pals have two
                     53: different sets of and-or logic driving the two inputs of an xor gate,
                     54: those two terms are number 200 + output pin number and 300 + ditto.
