Scripts and utilities supporting the Burroughs 220 BALGOL Compiler
reconstruction effort.
Unless otherwise specified, all files are in standard Windows text
format, with carriage-return/line-feed delimiters.
220-Format-Band-Disassembler.html
HTML/Javascript utility to disassemble words of a 220 Cardatron
format band into the notation used by the BAC-Assembler FBGR pseudo-
instruction. See instructions for use at the beginning of the
source.
220-Paper-Tape-Decoder.html
HTML/Javascript utility to translate Al Kossow's binary paper-
tape image files to the paper-tape image format used by the
retro-220 emulator.
BAC-Assembler.html
HTML/Javascript assembler for the assembly language dialect used
with the BALGOL Main, Overlay, and library functions.
BAC-DeckGen.cmd
Windows command-line script to generate card decks for BAC-Assembler
from the transcribed *.baca files for the BALGOL compiler.
BAC-Disassembler.html
HTML/Javascript utility to disassemble 220 object code from paper-
tape image files (in the format used by the retro-220 emulator) to
the assembly notation used by BAC-Assembler.html.
BAC-XScript-Reformatter.wsf
Windows VBScript utility to extract source code from the BALGOL
assembly listing transcriptions and reformat them into card decks
for use by BAC-Assembler.html
BALGOL-Dumpanalyzer.html
Script to read the text of a retro-220 memory dump taken while the
BALGOL compiler is running and do a partial analysis of the
compiler's tables.
GEN-Assembler.html
HTML/Javascript assembler for the assembly language dialect used
with the BALGOL Generator utility.
GEN-XScript-Reformatter.wsf
Windows VBScript utility to extract source code from the Generator
assembly listing transcription and reformat it into a card deck for
use by GEN-Assembler.html.
Mahon-PT-Xlate.wsf
Windows VBScript utility to translate the original paper tape files
for Michael Mahon's SNAP-1E assembler for the 220 to the paper tape
image format required by the retro-220 emulator.
See /software/SNAP-Assembler for more on that assembler.
Xlate-Card-PT.wsf
Windows VBScript utility to translate card image files to the paper
tape image format required by the retro-220 emulator. An optional
parameter specifies the number of words per paper-tape record. This
defaults to 14 for input to the paper-tape version of the BALGOL
compiler. It should be 16 for input to programs compiled by the
paper-tape version of BALGOL.
