Must you use 360K floppy ? May be your 3.3 machine only have 360K
drive. If you have FASTBACK, I am pretty sure it can backup the
file over several disks. Or if you have access to mkstk, the SPLIT
utility can cut your file up into 360K chunks.

Or worse come to worse, you can always write a small utility in C
or Turbo Pascal to read binary file and cut it up; don't forget
to write the utility to put them back together though.

How about this:

/* Should work in principle but might not in practice, and is
   definitely very kludgy. I wrote this right here.
   Therefore I am not responsible for what it does. */

#include <stdio.h>

main() {
FILE	*fp, *fo;
char	name[]="bigfile";
char	oname[200];
int	k,i,f;
int	each=350;		/* each file to be 350 K */

fp = fopen (name, "rb");	/* "b" for binary mode in MSDOS */
for (f=i=k=0; (ch = getc (fp)) != EOF; ) {
	if (k == 0) {
		if (f != 0) {
			fclose (fo);
		}
		sprintf (oname, "file.%d", f);
		fo = fopen (oname, "wb");
	}
	putc (ch, fo);
	i++;
	if (i = 1024) {
		i = 0;
		k++;
	}
	if (k = each) {
		k = 0;
		f++;
	}
}	/* for */
fclose (fp);
fclose (fo);
}
