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
We needed a file typer which would pause every screenful
without the need for MORE to be present. Having put it
on the disc to show the text files, we thought we might
as well document it.
Just use:
ITYPE filename
and you'll be prompted to press a key after every
screen of text.
Here's the source code:
/*
File typer - a screenfull at a time without
the need for MORE, by Barry Wood
Returns ERRORLEVEL=1 if wrong number of arguments
2 if couldn't open file
*/
#include <stdio.h>
#define NULL 0
#define WRONGARG 1
#define NOFILE 2
main(argc,argv)
int argc;
char *argv[];
{
FILE *fp;
int lcount;
int c;
if(argc != 2)
{
puts("\n\nUse ITYPE <filename>\n\n");
exit(WRONGARG);
}
if( ( fp=fopen(argv[1],"r") ) == NULL )
{
puts("\n\nCan't open the file!\n\n");
exit(NOFILE);
}
lcount=1;
while( (c=getc(fp)) != EOF )
{
if (c == '\n')
{
if (lcount++ == 20)
{
puts("\n\nPress a key ...");
getch();
lcount=1;
}
}
putchar(c);
}
putchar('\n');
fclose(fp);
}
