Compatibility & Integration The 9122D is recognized by HP 8753 network analyzers and maintains full compatibility with HP 110 and HP 150 computer systems. Direct substitution with contemporary 3.5-inch floppy drives is not recommended without modification due to proprietary connectors and controller signaling requirements. The non-standard ribbon pitch and interface protocol differ from modern drive implementations.
