[ICOM] Using IC-720a with PACTOR

[Cam and Juli Hedrick]

HI,
Does anyone have any experience with this?  I hope to set mine up for PACTOR
as a back-up to the 7800 and 756proIII.  What interface should I go with?
All advice greatly appreciated...the PRO III has gone down twice, and the
7800 had a programming glitch from the factory and is now at Icom.  The 720a
has never been in for service since I bought it new!
Thanks 
Cam
