        fpuproms.c -- Buchla 700 FPU Microcode PROM Utility
        Version (see VER below) -- D.N. Lynx Crowe

        This program takes an ASCII file giving the microcode addresses
        and data values, and creates 5 PROM files in Motorola S-Record format.

        The FPU700.DAT input file consists of 9 input fields, as follows:

                adr p1 p2 p2b p3 p3b p4 p4b p5

        where:

                adr     is the address in decimal for the data
                p1..p5  is the hex data for each prom

        PROM 2, PROM 3, and PROM 4 have separate data for each half, while the
        data from the first half is duplicated in the second half for
        PROM 1 and PROM 5.
