Thanks Audrey for your latest thoughts--- obviously you are showing a friendly concern.
Actually I have 2 original 'Initial Data disks '

At the moment our thoughts are around the 'Flash Memory'
We have been able to get the part number from the Service manual.
Audrey, the parts addresses that you sent as an attachment have replied only this morning and they have the suspect part
Seems like you have to have floppies to reload the replaced Technics Floppy Memory according to the manual----may-be they come with the New Part -- still waiting for further confirmation as to Forum Brain Boxes .
Has any Forum Member ever replaced the Flash Memory
Part No RFKFXKN7000. AND ANY PROBLEMS WITH DOING THAT ?
