Command-line utilities for Linux-style systems:
- CRC RevEng
Calculate CRCs and search for CRC algorithm parameters based on sample message-CRC pairs. Released under GNU GPLv3+.
- Base91 Version 3.01, 30 December 2018
Send binary data over an ASCII serial connection more efficiently than uucode or base64. Features run-length encoding.
- Base91 (195 KB, xzipped tar archive)
- Base91 (231 KB, gzipped tar archive)
- Base91 (248 KB, Zip archive)
- Base91 (251 KB, Zip archive for RISC OS)
- Httpdir.pl Version 1.2.6, 27 December 2018
A compact HTTP file server in Perl, for personal networks. Features PUT, DELETE, MKDIR and POST file upload, with selectable permissions. Released under GNU AGPLv3+.
- Flood and Drain Version 1.03, 9 February 2017
Simple tools to create files of pseudo-random data or zeroes.
- Drumlins Version 3.03, 20 May 2015
Compares recursive directory listings (the output of ls -lR, cksum, md5sum or sha1sum) taken on different dates and prepares a Bourne shell script to manipulate the old directory to match the new listing. Outdated files are saved in a user-supplied 'reject tree', or deleted. Also writes an FTP script for a DOS or Linux FTP client to fetch files that have newly appeared or have been updated.
- crcbfs.pl Version 1.03, 19 May 2009
The predecessor of CRC RevEng. First posted to Lammert Bies' forum. Intended for CRC experts!
An update to an unusual BBC filing system:
- EDOSPAT Version 4.93, 17 January 2019
Applies patches to an image of Opus EDOS 0.4. A versatile alternative to DDOS which is now compatible with ADE Plus, Xfer 5.3 and HADFS. There are two parts: (a) addition of OSWORD calls 7D/7E and fixes for OSGBPB and OSARGS, (b) support for seven common floppy disc controllers including those in the B+ and Master.
- EDOSPAT Version 5.23, 17 January 2019
Quad density version for modified controllers only. Supports Opus 2791 HD and Acorn-style Ajax.

A data integrity tool for ARM Tube OS:
- PLASS Version 0.2, 23 August 2011
Adds a payload assurance routine to an ARM Tube OS executable to verify that it has loaded correctly before running.
- PLASS (10 KB, Zip archive)
A mild compression algorithm for BBC ROMFS ROMs:
- CompROM Version 1.20, 18 June 2014
Creates ROMFS ROM images with compression (so that files can be loaded from an EPROM in the BBC Micro.) Implements run-length encoding and a recursive dictionary; not strong compression by modern standards, but maybe enough to 'make it fit'.
Works around two MOS bugs identified by John Kortink, relating to *RUN and OSFILE. A non-compressing version is included for dense files.
- CompROM (34 KB, zipped Perl 5 script and Basic assembler)
Four items related to BBC file transfer:
- UEFwalk Version 1.51, 11 March 2017
Verify, summarise and extract data from BBC emulator files. Compliant with UEF specifications (ElectrEm) up to the latest v0.10. Requires Perl 5 and Gzip. Includes Kleen, a suite of scripts for creating high fidelity UEF files from cassettes.
- SD/DD/HD multi-formatter Version 2.23, 12 April 2010
Directly drives some 1770 and 2791 controllers to format discs to BBC Micro and PC norms. Writes 1.4 MB High Density on compliant hardware (from a 6502 CPU running at 2 MHz); the NMI routine and ancillary loop may be of interest to 6502 programmers.
To solve the chicken-and-egg problem of formatting a disc to install the formatter on, these releases include a number of options to create a formatted DFS disc from scratch.
Both these archives contain:
- SSD disc image
- Text 'shell archive' for serial transfer
- UEF file for cassette loading
- MP3 file for cassette loading
- XFer in C Version 5.3a, 6 June 2014
Transfer files and disc images to and from a BBC Micro over a serial link. A popular, easy-to-use command-line utility written by Mark de Weger, ported to C by Angus Duggan and extended by Jon Welch. Now with CTS/RTS handshaking support and more flexible INF file handling.
- DT2K6 Version 3.01, 26 July 2006
Transfer files and disc images to and from a BBC micro over a serial link. The host can be any ASCII terminal with a logging facility; the log can be decoded elsewhere using common archiving programs. There are also programs to copy files between BBC discs and cassettes.
An extension to a venerable graphics editor:
- XVUEF Version 1.01, 3 June 2005
An unofficial patch to add UEF support to the shareware imaging tool XV, version 3.10a. Open, view and save inlay images and read instruction manuals. The 1995 vintage application is simple to extend and can create highly compressible images.
- XVUEF (11 KB, zipped patch file)
