F/ADFS3
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.

To my mind the two most useful expansions of ADFS are a second drive and ADT. I couldn't manage without either. My second drive is a 5.25 in so that I don't mix up my backups. Remember though when buying a 5.25 drive to ask for a BBC B compatable,double sided double density 80 track. There are a number of PC 5.25 drives comming onto the market now and while these will work they start up as soon as you insert the disk. This can be very annoying. As for a 3.5 in drive try to get a double sided double density one. It is unlikely you will be offered a high density one cheaply as these are still used frequently on PCs but this will be changing soon as PC owners dutyfully obey the latest instructions from the PC press to ditch what they recently spent hundreds on and buy the latest gear if they don't want to look naff. Power supplies for second drives must be used. There are a number of ex-PC switched mode supplies around which will have the connecting plug for 5.25 attached. Make sure it is cased as high voltages are generated inside. Also you will need to put a load resistor across the output since switched modes don't like sitting around doing nothing. I use a 15 ohm 10 watt one which I bought from Maplin. I didn't solder it in, I pushed the wires into the output plug on the supply across the 12 volt line. Most switched modes have a legend on the side givingthe output configuration. A supply for a 3.5 in can be an old PC switched mode but you will need to change the plug or get an adaptor. These do exist but can be tricky to find. Most 3.5 in drives don't need very big supplys. 12 volt 1 amp with 5 volt at .5 amp is usually sufficient. Plugs can be bought quite easily but be careful of the configuration. For both the 3.5 in and the 5.25 in drives the middle two pins are 0 volts. The 5 volt and 12 volt go on the out-side but must not be mixed up. 3.5 in 5.25 in . . . . / . . . . \ ---------- |____________| 12v 0v 0v 5v 5v 0v 0v 12v Supply sockets for 3.5 in and 5.25 in drives looking at the sockets on the drives. Well that's my intro to using ADFS. If there is anything which I have left out, or anything which is not clear then SEND IT IN. I wrote this because members asked for it. If there is some aspect of the Elk which is causing problems, ask for help. That's what a user group is for. SEND IT IN. DONT PRESS 'R', THERE IS NO PROGRAM TO RUN
