How do I do two F6 disks?

One possibility: There is something wrong with the diskette changeline on
your computer.

Background Info:

The diskette changeline is the electrical signal from the floppy disk to the
computer indicating
that a diskette has been ejected from the drive. Proper operation of this
hardware signal is
required whenever the OS needs to deal with multiple floppies in sequence.

Things to check:

1. The diskette changeline signal is one of the outer wires on a floppy
cable. As a result, it
is commonly the wire that gets damaged when a floppy cable is abused for
whatever
reason. Replace the floppy cable on spec to verify this.

2. Floppy drives go bad. One of the ways they go bad is the diskette
changeline signal
doesn't work. Sometimes this can be fixed by disassembling the floppy
and cleaning
the dust bunnies out of the switches for write-protect and
diskette-changeline that are
usually mounted near the front of the diskette-carrier. In other cases,
replacement of
the floppy drive is required.

3. You can check the diskette changline system by booting from a DOS floppy,
reading a
DIR from the floppy to see the files on the boot floppy - and then
ejecting the disk and
changing to another disk with different files. When you DIR again, the
system should
know the disk has been changed and rescan the disk. This should result
in the new
files showing up in the DIR list. If you still see the old files, then
your diskette
changeline is broken and the system needs repair as noted above.


Hope this helps.
