This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.
Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

User Guide to the BBC Telesoftware / Met Office Satellite Data Service
======================================================================
Introduction
============
The satellite image data service is a joint venture between the BBC and
the Meteorological Office. The aim is to provide telesoftware users with
the latest weather satellite data from the MeteoSat satellite.
The Meteorological Office receive such files regularly as part of their
weather forecasting material. These files are sent to the BBC's weather
department computers for use in the BBC weather programmes.
BBC Telesoftware intercept some of these files, take copies of the data
received from the Met Office, process them, then make them available a few
hours later as Telesoftware files.
Data Format
===========
The format of the data broadcast is based on the format used by the Met
Office, but is not identical. (This, of course, is not the format of the
data as transmitted by the satellite, as the Meteorological Office carry
out a great deal of enhancement and compression processing to the original
data before passing it on.) If you wish to use the data from these files
in any way other than to create computer screen displays, you will need a
copy of the data format protocol which is available separately.
Receiving The Satellite Data (Downloading)
==========================================
For the BBC micro, the program "SatLoad" gives access to the currently
available files within the satellite data service. For IBM machines, a
similar utility, SATLOAD.EXE, is provided with the BBC approved teletext
card - if you do not have this, please contact your adaptor card supplier.
To use, type CHAIN "SatLoad" (BBC Micro) or just SATLOAD (IBM pc). The
software will search for the catalogue file. To do this, it looks at the
TSDP (Television Service Data Packet) for the main index page number, then
follows link 5 of the main index page to find the main telesoftware
catalogue, where link 5 again will lead to the Satellite Service
catalogue. Under normal circumstances, the computer will find the
Satellite Service catalogue within about 15 seconds. Once found, details
of each file available in the service will be displayed.
During the time the system is searching for the correct catalogue, the
prompt "L = Latest image" is displayed. If, during this time, the "L" key
is pressed, the program will search for and download the latest available
satellite image data, only displaying the catalogue details when this file
has been saved to disc. There is no response by the computer when "L" is
pressed, but it will have been noted! If you prefer to select the files
manually, do not press "L" - just let the program receive and display the
catalogue entries in the normal way. In either case, the catalogue will be
found and displayed for a (further) selection.
Files are presented in a similar format to the normal telesoftware
catalogue, and the cursor up and down keys should be used to select the
required file. If more files are available than will fit on the screen, a
message indicating the total number of available files is displayed, and
pressing the down arrow will reveal the remainder.
To download a file, move the bar to the required file, then press RETURN
or ENTER. Downloading is fully automatic, following which the catalogue
will be displayed again for further selections. If no further files are
required, press ESCAPE. Confirmation of this is then required by pressing
ESCAPE a second time.
The downloaded data files will remain on your currently selected disc.
Remember, however, these files are not "screen dumps" but are data files
based on the data received from the satellite.
Converting The Data Into a Computer Screen
==========================================
Possibly the most useful way of using the satellite data is to create a
computer screen image from it. Our service includes software to do this on
three types of micro - the BBC Microcomputer (with or without the 6502
second processor); The Acorn Archimedes; and any IBM compatible pc.
"Display" is the BBC Micro (models B, B+, and Master) version, to create
mode 2 screen images. The routine takes some time to complete, but will
generate a colour display showing cloud position and thickness, with each
colour representing a different cloud thickness. This is best viewed on a
monochrome monitor, where each colour is represented as a grey level.
Note, however, that the BBC Micro, and some IBM display cards, are
incapable of producing the fine resolution available from the data files,
so accurate studies of cloud thickness are best made using the original
data file rather than the screen image.
"ArcDisp" is a similar routine for the Acorn Archimedes computer. The
cloud thickness is more accurately portrayed as one of 16 grey levels, and
a higher resolution is possible than on the BBC Micro.
"SATDISP.EXE" (available shortly) will create a screen display on an IBM
pc or 100% compatible, automatically giving the maximum possible
resolution and picture size with the display device present.
A VGA board will give the best results, but most other display devices are
catered for, including EGA, CGA, Amstrad, Hercules and some others. As
with the BBC Micro, colours are used to represent the different levels of
cloud thickness, so a monochrome display will show these more effectively.
However, most monochrome monitors are only for use with monochrome display
adaptors which are incapable of the high-resolution graphics needed!
When complete, the display will be saved to disc as a screen dump, ready
for re-loading when required without having to use the display program
again.
Each screen is saved under a unique filename comprising the 7 digits of
the Julian Date integer (the least significant 4 digits for BBC DFS
systems, and the least significant 5 digits for IBM/MSDOS systems), plus
the first 2 digits of the Julian Date fraction. This is then prefixed with
a single alphabetic character relating to the area covered by the image.
Note the filename is derived from the full Julian Date, and not the
Modified Julian Date more commonly associated with computing applications.
In this way, each screen can be easily identified and sorted into order
within other utility software. It may be worthy of note that the full
Julian date (integer part) increments at 12:00 midday, whereas the
Modified JD increments at 00:00 (midnight).
IBM and MSDOS files will also be given the filename extension of .SCR to
signify a screen image.
For example, the Julian Date for Midday, Wednesday 15 February 1989 is
2447573.0000. Files created for this day would be:
Midday Atlantic: 18:00 European:
IBM: A4757300.SCR E4757325.SCR
BBC: a244757300 e244757325
BBC (DFS): a757300 e757325
Utilities
=========
There are many uses for both the satellite data and for the screen
displays. Some of these have been catered for in utility files, and we
hope users of the service will define other areas and be able to offer
other utilities for distribution via Telesoftware.
a. SatSeq (BBC micro)
---------------------
"SatSeq" is a BASIC program for the BBC Master computer, and allows a
quantity of screen displays from a disc or discs to be displayed in date
sequence.
To use the program, LOAD "SatSeq", then insert the disc or discs holding
the screen images. RUN the program, entering the appropriate disc drive
information as requested. If no drive is specified, drive 0 will be
assumed by default. The program will find all the satellite screen images
on the discs, sort them into order, then cycle through each one in turn.
Press f0 to toggle on or off an automatic cycling routine - displaying
each successive screen in turn starting from the currently displayed
image. The time interval between displaying each screen is set to 0 by
default, but can be altered by changing the parameter near the start of
the program. Alternatively, using the cursor keys (when not in automatic
display mode) will step through the images individually:
Up Arrow = Go to start of sequence
Down arrow = Go to end of sequence
Left arrow = Back one image
Right arrow = Forward one image
<RETURN> = Quit
These functions may be re-allocated to other keys if preferred, by
altering the variables near the start of the program.
It would be logical, particularly when using ADFS, to save the screen
images in a specific directory, for example: $.SatScreens. The particular
directory searched by the program must be the same for each disc
specified. It is, by default, the root directory, but may be changed by
altering the string allocated to the variable 'directory$' near the start
of the program listing.
"SatSeq" can be modified for use on a BBC Model B or B+ computer (DFS
only). Load the program (version 2.18), then delete lines 60, 70, 570,
580, and 910 to 1190 inclusive. This will give enough room for the
procedures to operate, but with large numbers of images for display you
may also need to lower the value of PAGE to &1900 before use. These
modifications are required solely due to the lack of available memory on
these older computers.
Although "SatSeq" V2.17 has been designed for use with Econet, problems
still exist with some systems. A new version will be available as soon as
these difficulties can be identified and corrected.
2. SatShow (BBC micro)
----------------------
"SatShow" is another BASIC program for BBC Master machines, Archimedes, or
Model B or B+ with shadow screen upgrade, and will display the file header
information from any specified data file (not screen image). The format
and content of the file header is detailed in a separate document. For IBM
pc's, the header information to each file is detailed when "SATDISP.EXE"
is run.
Using The Service With Other Computers
======================================
The Satellite Data Service is fully compatible with almost any make or
type of computer with a disc drive (or other storage medium that supports
Random Access file handling) and a suitable graphics display mode. A
teletext adaptor, capable of correctly receiving and decoding
telesoftware, is required, and software to find and interpret the
catalogue and to display the received data file, must be written if the
computer's operating system is not compatible with BBC or IBM/MSDOS
computers.
Copyright
=========
Copyright exists on all data, programs, text or other files broadcast by
the BBC. The situation is as follows (the term "program" includes any
computer readable file - text, data, software, or binary file):
(1) Domestic users of a program broadcast on CEEFAX may:
- make two copies only for private purposes.
- adapt or modify it for private purposes but not for sale.
(2) Educational and training institutions and agencies may:
- record and use the program for their own educational training
purposes but not for sale.
- adapt, modify and distribute a program for their own educational and
training purposes, but not for sale.
(3) No part of a program may otherwise be reproduced, stored in a
retrieval system or transmitted in any form or by any means, without
the prior permission of the BBC, except in accordance with the 1956
copyright act.
