The AIS set made by NASA is under half the price of the set made by Comar. I am aware that the latter will work on 'Passage Plus' Software, but am not at all sure as regards the NASA set - I assume so, but prefer not to waste even a hundred pounds, unless someone here has tried it.
What about drivers for the Mac? I run under OS 10.5.6 BTW
Thanks, Philip

I think your concern is unfounded.
AIS units communicate over a serial (RS-232) port that these days is most often converted to USB physical bus but in SW is a 'virtual serial port'. So this is pretty much platform, software and OS independent. All AIS units speak the same language and use the same mechanism (serial port) to talk to the program.
In case of the NASA 'AIS Engine 2' their output spec is:
( NMEA 2000/0183 (38400 Baud) VDM encapsulation string conforming to ITU-1371 )

I know of at least one user who is using the NASA AIS 2 without problems. You will need a serial:USB adaptor, and the driver will depend on which adaptor you use. For example, the Keyspan USA19HS adaptor and the Aten UC232A adaptor each have their own drivers available from their websites.
