Thanks.

I just looked at DDC and have posted them a question on the minimum number 
of I/O lines needed to interface Their ACE to a embedded controller.  The 
data sheet would indicate about 40 - as in a PCI bus or the like.  A 
nonstarter for us.

What we really need is a serial to 1553 converter sort of like the simple 
serial to RS-422 chips on the market, but which does the protocol as 
well.  Or even the CP2101 and similar RS-232 to USB converters.
