I have a NC4000 system that I added a XT floppy
controller
 and an XT hard disk controller, years ago. I even used an
 old 5 meg seagate drive. 
   Oh my, I drool uncontrollably.
   I have a few Harris RTX-2001 chips, but haven't put 'em on a board yet.
 I've never even SEEN one of the Novix chips.
 
 
 Wireless world over here had a reader offer and I got this little demo
 Novix based board
 as you can see it is a Mostek made chip so its not obvious from the
 outside what it is
 what paper work I have is listed at
