XF551 Alternate 8.333 MHZ OSC Plug-in Board


Available on backorder


Finally a working alternative XF551 OSC circuit.   Over time the various parts of the XF551 floppy drive main board are getting harder and harder to locate.   One of those parts was the original 8.3333MHz oscillator in the full can version.  Short of designing a custom oscillator, this plug in board comes closest to serving as a replacement for that oscillator.

This replacement comes fully assembled and tested on an otherwise working XF551 5.25″ floppy drive.  It can be used for either the 3.5″ or 5.25″ versions of the XF551.
