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.

File contents
� The program "Error" in this directory has a deliberate error.
� You can use this to try out error throwback with DrawBasic.
STEP 1 Make sure !Edit is on the iconbar (or other appropriate editor�)
STEP 2 Double-click the program file "Error"
STEP 3 After the throwback window opens click the button marked
"Throwback"
STEP 4 Remember to close the throwback window. Each such window
uses 32K memory.
Footnotes:
----------
� All Error throwback does is to automate the process:
� Open an editor window containing the offending program
� Then press the "GO TO" key F5
� Type in the (logical) number of the offending line
� Press the "OK" button (equivalent to pressing RETURN)
� Mark the line
Error throwback sends the appropriate commands to perform
this. It works with most editors which conform to the
"standard" configigurations of function keys etc. E.g.
� !Edit
� !StrongEd (Tested version 2.50)
� !DeskEdit (Tested version 2.02)
Unfortunately throwback does not work with the
excellent editor !Zap (tested version 0.80)
