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 3.11, 18 November 2019
Send binary data over an ASCII serial connection more efficiently than uucode or base64. Features run-length encoding.
- Base91 (203 KB, xzipped tar archive)
- Base91 (244 KB, gzipped tar archive)
- Base91 (263 KB, Zip archive)
- Base91 (266 KB, Zip archive for RISC OS)
- Httpdir.pl Version 2.2.0, 1 September 2020
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 3.04, 5 November 2019
Compares recursive directory listings (the output of ls -lR, find -ls, cksum, md5sum, sha1sum, sha256sum or sha512sum) 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 Outdated files are saved in a user-supplied 'reject tree', or deleted.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 Versions 7.02 and 5.62, 13 October 2020
A patched 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 71/7D/7E and enhancements to OSFILE, OSGBPB and OSARGS, (b) support for eight common floppy disc controllers including those in the B+ and Master.
Version 5.62 is a quad density version for modified controllers only. Supports Opus 2791 HD and Acorn-style Ajax.
- EDOSPAT Versions 7.01 and 5.61, 5 September 2020
Applies patches to an image of Opus EDOS 0.4.
The patch programs have reached their maximum size; these archives remain useful as a base for modifications.
- Prior versions of EDOSPAT with the original OSARGS. Setting the pointer has no effect until the next read or write operation. Files can be extended instantly – at the price of leaving undefined any part of the file to which you do not write!

A data integrity tool for ARM Tube OS:
- PLASS Version 0.2a, 2 October 2019
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 2.02, 13 September 2020
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 (35 KB, zipped Perl 5 script and Basic assembler)
Five 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 2.26, 19 September 2020
Directly drives some 1770 and 2791 controllers to format discs to BBC Micro and PC standards. 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 5.3b, 15 June 2020
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.
- DT+ Version 3.13, 19 September 2020
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.
- DT+ (94 KB, zipped 'shell archive', SSD image, UEF file and text listings)
- README (20 KB, text)
- DFSfix and Chafix Version 5.3, 3 September 2020
An extension to Acorn DFS, Opus DDOS and Opus Challenger to support RISC OS programs running on the SPROW ARM7TDMI coprocessor, and provide an extended interface useful to all programs. Included in CRC RevEng and Base91.
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)
