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 Gus,
Many thanks for the latest EUG33 and the corrupted disc. It was good of
you to try and fathom out/recover the discs contents and I appreciate the
remarks from Robert Sprowson about the problem, but as the person in
question is happily soldiering on with his new set-up I've decided not to
waste any more time on it. In passing though, I also suspect there is a
partial fault with the DFS chip, as Robert suggested.
I have decided to upgrade from my A3010 to something more modern and
fancy the new A7000+, which will do for me when fitted with a SCSII i/f.
To help fund the upgrade I have cleared out the attic of all the old stuff
and am in the process of cataloguing it. There are loads of ELK stuff,
BBC, Master and some PC bits, plus some unusual items from my Broadcast
days. In view of this could you insert the following ad in the next EUG,
viz:-
Loads of Electron Hardware (Acorn, Slogger, Pres, Jaffa, etc.) plus
software on tape, disc & Roms, magazines, books, user guides. Some
BBC, Master & P.C. bits. Much too much to list (approx 10 sheets)
send
SAE to D.E. WILLIAMS, 26 CHAMBERLAIN RD., LLANDAFF
NORTH, CARDIFF. CF4 2LX
By the time this appears I will have the list printed out and I'll send
you the first one off the press. In the meantime, one more item for
EUG:-
Having aquired one of the newer digital cameras (supprise birthday
present) I was appalled to find out that they sell the A.C. adaptors
separately and at an exorbitant price of 60+. Surely this is a bit of a
rip-off as I bet I could build a regulated DC supply for less than a
tenner, which I intend to do. Before I stick the end into my expensive
toy I thought I'd better make a few enquiries regarding these adaptors.
Has any members had experience, bought one, or know if there is anything
special about them? The spec. only states 6.5 - 7V DC, but no current
consumption figure, but I suspect it could be as much as 1 - 2 Amps. The
camera is run from 4 AA cells and according to mag articles the biggest
drain is when the 2" screen is on and during transfer to a computer.
Any info would be much appreciated.
Keep up the good work.
Re your camera, would rechargable batteries be too inconvenient?
Maplin sell NiMH AA cells for 5.49 each. These are better than NiCad which
tend to have the dreaded memory effect. The charge in my experience lasts
a lot longer than with ordanary batteries and ofcourse you can re-use then
hundreds of times. I am not sure what sort of charger they need but I will
look into it. Think carefully however before spending tons on a super
duper charger which does everything that you don't need or equally a
cheepo which will shorten the battery life to about 50 charges. You will
probably be best getting 8, 4 to use 4 for spare. And at the end of the
day with a capacity of 1200mAh you may get better battery life without the
inconvenience of a mains adaptor.
I have a little experience of mains adaptors for high tech equipment
partly from some servicing work and also from my 386 notebook PC.
On my 386 the power plug is infact a 5 pin mini DIN plug. The power comes
down two of the lines as normal but there is also another two lines used
as a signal and return path. So the power comes into the computer,
sends a signal up the signal path, this is returned down the other path
and the computer works fine. No signal path and the computer will turn on
but the hard drive doesn't work properly and did eventually corrupt
itself. Soon after the power switches the computer off.
I checked inside the power pack and there is only one 5V + and - line, no
-5V or 12V but some circuitry for this handshaking signal.
This was used by Comodore on their 8 bit machines with tape drive. The
shops told people that an ordanary tape recorder would 'blow ' the
computer. Infact there was a handshaking line which was connected to a
micro switch under the play key on the tape recorder. If this micro switch
did not connect these two handshaking lines at the same time as the play
button was pressed the computer crashed. The solution was to rig up a
switch and to turn it on at the same time as the play button was pressed.
Sadly my notebook PC and other 'high tech' equipment which I have seen
seems to want an elaborate signal.
Now all might not be lost. Firstly what sort of connection does your
camera need? Is it a Power Plug? If so then chances are there isn't a
handshaking signal needed, though one might be expected modulated onto the
power line itself.
Do you know the polarity? This is important beause dispite the cheapness
of a diode to protect against wrong polarity few manufacturers put one in.
If you don't mind me saying the current consumption is unlikely to be a
large as 1 to 2 Amps since using AA cells they would get really hot.
Remenber 2 amps with 6V this would be 12W
I once had a 12W soldering iron which burned its way through a carpet
belonging to the mother of a girlfriend who I had hoped would solve all my
problems. No-one would believe me when I said that I had re-arranged the
lounge to make better use of the space and they were not impressed when
they discovered that in the process of re-arranging the china cabinet a
spode plate had slipped and crashed onto a spode cup and saucer. A tangled
web indeed.
But I digress.
