I have two such drives which work with the Versafloppy II and Jade Double-D, but will do NOTHING on the UFDC-1. Various things such as adjusting terminating resistor packs have had no effect. The only difference I have been able to find is that the UFDC-1 uses a special data seperator chip where others use op-amp based designs. Losing the use of a 784K drive on my portable system is painful. Can anyone help? Hal Bower Bower at DCA-EMS
