3 fpuproms.c -- Buchla 700 FPU Microcode PROM Utility
4 Version (see VER below) -- D.N. Lynx Crowe
5
6 This program takes an ASCII file giving the microcode addresses
7 and data values, and creates 5 PROM files in Motorola S-Record format.
8
9 The FPU700.DAT input file consists of 9 input fields, as follows:
10
11 adr p1 p2 p2b p3 p3b p4 p4b p5
12
13 where:
14
15 adr is the address in decimal for the data
16 p1..p5 is the hex data for each prom
17
18 PROM 2, PROM 3, and PROM 4 have separate data for each half, while the
19 data from the first half is duplicated in the second half for
20 PROM 1 and PROM 5.
