Due to the lack of response to my previous posting, I am forced to ask again...
Please reply if you have any inkling as to the correctness of my theory!

I would like to use an Octal Buffer/Line Driver in a circut I am building which
uses the Amiga external disk port.  The disk port requires Open Collector and
Open Drain devices to be present.  I am wondering if I can use a 74HCT240 at
this point to read and drive the OC and OD.  Also, is the float state on the
tri-state 74HCT240 going to be valid for the Amiga external drive port?  If I 
use 4.7k pull-ups on the OC inputs (from the Amiga) and 4.7k pull-downs on the 
OD outputs then this should work fine, right?

Thanks in advance for your help.
