    This can be gotten from your local Regional Technology Center.
A quick run down on the differences is that a T425 has 4KB of
internal RAM, T800 style links, 2D block move support and (as a
consequence of the 2D block move support) a different value for
MemStart.

    You can get a newer and better worm with source code from our mail
archive server.  The email address is archive-server@inmos.COM.  By
the way, we're having some problems getting news articles out on the
net; if you would be so kind, please post the information in this
message for me.  Thanks.

    Ditto.
