Three items related to BBC file transfer:
- DT2K6 Version 3.01, 2006-07-26
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.
- UEFwalk Version 1.50, 2008-03-25
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 2.11, 2009-02-18
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. The .zip file contains Basic 'shell archives' to create a DFS disc from scratch.
An update to an unusual BBC filing system:
- EDOSPAT Version 4.82, 2009-08-11
Applies patches to an image of Opus EDOS 0.4. A versatile alternative to DDOS which is now compatible with ADE Plus, Xfer 5.1 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 5.12, 2009-08-11
Quad density version for modified controllers only. Supports Opus 2791 and Acorn-style Ajax.
An extension to a venerable graphics editor:
- XVUEF Version 1.01, 2005-06-03
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)
A mild compression algorithm for BBC ROMFS ROMs:
- CompROM Version 0.40, 2009-04-04
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 (27 KB, zipped Perl 5 script and Basic assembler)
Command-line utilities for Linux-style systems:
- Drumlins Version 3.02, 2004-03-05
Compares recursive directory listings (the output of ls -lR, cksum or md5sum) 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.
- Base91 Version 1.03, 2009-11-13
Send binary data over an ASCII serial connection more efficiently than uucode or base64. Features run-length encoding and self-delimiting streams.
- Base91 (15 KB, zipped Perl 5 script and BBC BASIC program)
- crcbfs.pl Version 1.03, 2009-05-19
Search for CRC algorithm parameters based on sample message-CRC pairs. First posted to Lammert Bies' forum. Intended for CRC experts!

A collection of ROMs contributed by Stairwaytohell.com user 'Lorfarius' via 'Sorvad', plus selected ROMs from The BBC Lives! (860 KB, zipped)
New! 2009-06-21 UEF files compiled with the aid of Kleen from 2002 to 2009. (5.7 MB, zipped)
VLSI SERPROC compatible versions of Basicode 2, Caveman Capers, Facemaker and Fortress. (1.4 MB, zipped)
- The Ferranti serial ULA reads everything in
original/ and fix/.
- Use either the original or fixed BASICODE translator to read original sample programs.
- The VLSI SERPROC reads everything in
invert/ and fix/.
- Use the original BASICODE translator to read inverted sample programs.
- Use the fixed BASICODE translator to read original sample programs.
Here is a catalogue of common CRC algorithms, re-specified within the Rocksoft™ parametric model. Includes 6502, ARM, 8051, 8080 and Z80 assembly code to implement a selection of the algorithms.
Or for some light relief, how about a play.
