Thanks guys. Our club will probably update our old laptop to a new one and latest Alycat but might hold off on the decoder till this plays out a bit longer.
Interesting you mention the Serial/USB converter Jeff. I remember earlier in the year trying to get our decoder to work on my new laptop. I bought a Serial/USB converter from Jaycar. I could never get it to work though. Couldn't recognise the Decoder at all. I put it down to being a Windows 7 thing and gave up. Now we do want to buy a new computer though. It might have been the Serial/USB converter not doing it's job. I did read there are problems with some brands.

Do you know of a particular brand/model that is known to work with the AMB2 ?
