8.9 Interface for External Floppy Disk Drive
An external floppy disk drive can be connected to the 25 pin DSUB socket (see Chapter 7
"Accessories").
It is not possible to operate a second parallel device on this interface.
These settings cannot be changed.
Because of general PC specifications, this interface should be handled with extreme
care with regard to EMC, location of cables etc. It should therefore only be used for
service.
