Hi Larry,

REVXA.4 (soon to be released) of the OZY has a DB25 connector and
interface to emulate a parallel port.  This will allow direct control
of the SDR-1000.  When not used with the SDR-1000 this port serves as
general purpose local IO.  There is also 4 high current/ high voltage
open collector outputs now.  We also have a 16 bit logic
analyzer/debug port available.  I have tried to make everyone happy!
