[sdiy] U-20 initialisation and backups

[Peter Blackett]

Dear Tony and list,
I think you do have to be carefull initialising some of the keyboards 
from this vintage, as sometimes some ( all ?) of the preset sounds are 
held in ram,and the initialisation precedure only loads a couple of 
these not the whole lot.
there used to be a rom or ram card available with all the preset sounds 
on it,but I don't know if these are still available ?
the rubber contact strips ona lot of older keyboards do seem to be 
wearing out now.
regards Peter
