 Anybody has a datasheet for them ? 
 I don't, I only suggested this
because the CXY08 print sheets are
 available in the archive and it looks like a compact simple Qbus
 interface.  
 DC021 is in the "Digital Semiconductor Databook 1987 Volume 1".
 If it's not yet on Manx, I can supply just the relevant pages
 (the entire thing is quite large).
