We welcome new members and have a plan in place for distribution of the Team prize back to our active membership. Active members gain by participating in the iXorg Team. There is a client for nearly every kind of computer, so you don't have a valid excuse to not participate. Not big iron by a long shot. Everyone has a chance of finding the correct solution.
Every computer contributing to the effort is an asset.
The RC5 algorithm, for instance, depends heavily on 32-bit data manipulations. The current set of clients all use 32-bit code that won't execute on these earlier machines. Check to see if the client is already running on the system you are using. Running lots of copies will not help. Firewalls need to allow Outbound initiated TCP Sessions at port 2064 to transfer inbound and outbound data blocks with the client machines.
