Help/DownLoad

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.

  Sometimes, a BASIC program that would
run using  cassette tape  will not work
with ADFS, giving a "No room" error  or
similar.  In this case, it is necessary
to "download" the BASIC program.   This
process is described in the Plus3  User
Guide.

  In addition to the procedure set  out
in the  User Guide for recovering ADFS,
it may be  possible to reaccess ADFS at
the end of your program.   This  may be
necessary if you wish to chain in  more
BASIC programs from disc, for example.
 
  Sample programs for the download  and
recovery  procedures  are given  in the
file $.LIBRARY.BASIC.DownLoad. They may
need to be tailored to your  own  case.
It is possible that your BASIC programs
may have special requirements that mean
that the procedures may not work in all
cases, but they should usually be OK.

  It should not be necessary to  employ
the download technique if you are using a second processor.
