[High-Speed-CW] K4KN keyboard schematic needed

[ve3gf]

My long time friend Murray VE3HEU gave me his K4KN cw keyboard, the one 
with the 3 key roll-over, but did not have the schematic for it.  The 
high speed range no longer works, and I need the schematics for 
repairing my gift.  My friend is severely sick with cancer and wanted me 
to have this as a memento of our friendship that dates back to my 
college days when I met him on the air.   An electronic copy of the 
schematics and whatever manuals would do, or  I could send a charitable 
soul my address if a paper copy were available.
