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.

Dear All,
Sorry about missing the deadline for the last issue - it was
half way through my exams,so I concentrated on book work not keyboard
work! Yes - I did pass...
Matters to tidy up from past issues:
1.The main menu
===============
When toggling between 40 and 80 column modes,there's no need to update the
whole screen.Change the following
660 adjust to ("PTI12345",CHR$(GET AND&DF)) for case insensitivity
680 ends in PRINTTAB(10,5);8-(4*ABS(M%));:GOTO660
570 set default "Toggle 80 column text"
2.Startup screens
=================
Whoever submits these has a great deal of skill and patience.I am always
impressed by the opening screen - keep it up!
3.Packed up disk drive
======================
DE Williams had a Master for the BHF which had stopped writing to
disks.Well assuming you've eliminated the drive itself (by testing
different drives with known working machines) then the machine is to
blame.Check for dry joints first.The only other thing I can think of is
that when the PSU blew up it took part of the disk controller circuitry
with it.On a Master this is hard to check as few chips are socketed and
chp faults can be hidden by the peripheral bus controller (one of the
custom 40 pin chips inside).The PBC could itself be at fault.Gosh.
4.Disk faults
=============
Acorn app note 019 lists the disk faults,and disk fault &18 is 'sector not
found'.Acorn's suggestion is that the disk isn't formatted.
5.Build it III
==============
This month I've sent a disabler design which can be used to turn on and
off anything (incl.mains!) WITHOUT a single byte of software.
6.Mode 0 EDIT
=============
This should have appeared on issue 32 but exams meant it missed the
closing date.It's got a heap of assembler in it now so simple manipulation
of graphics should be LOTs faster.
Enjoy the summer...
Robert Sprowson.
THE START-UP SCREEN IN EUG31 WAS BY DOMINIC FORD. HE SENT AN EQUALLY
IMPRESSIVE ONE FOR EUG32 WHICH I FORGOT ABOUT. UNFORTUNATELY
RE-PROGRAMMING IT NEEDS HIS INTELLIGENCE AND ABILITY SO HOPEFULLY WE CAN
ALL SEE IT LATER.
THE DISC PROBLEM SUFFERED BY D E WILLIAMS WAS A LITTLE MORE COMPLICATED.
HE SENT ME ONE WHICH I DIS-ASSEMBLED USING ADI. THE WHOLE FIRST SECTOR IS
DELETED AND INTERMITTANT SECTORS ARE ALSO BLANK. THER DOES NOT SEEM TO BE
ANY PHYSICAL DAMAGE TO THE DISC ITSELF AND TALKING TO Mr WILLIAMS THE
OTHER DISCS HAVE SUFFERED A SIMILAR FATE.
ANYWAY CONGRATULATIONS ON PASSING YOUR EXAMS.
