Newcastle upon Tyne   6 July 2006       For Immediate Release

Pattotek announces investment opportunity in Castle Technology Ltd

Pattotek Ltd owns a 30% share in the voting capital of Castle
Technology Ltd ("Castle"), owner of the RISC OS Operating System
and developer of RISC OS based desktop computers.  Pattotek Ltd today
announced that, due to diverging business interests, it is examining
its options regarding Castle and would like to hear from potential
investors in the RISC OS community who could be interested in gaining
control of this stake in Castle.

Pattotek's CEO, Pete Wild said, "after almost 20 years personal
involvement in RISC OS, it is regrettably no longer core business and
we must consider what is best for the future of the OS".  He added,
"However, Castle still has a dynamic management team, and exciting
new plans for the future of RISC OS; here is an opportunity for the
user community to have more of a say in those plans.  Given the past
history between Castle and RISC OS Ltd, this could represent a chance
for the re-unification of efforts to move RISC OS forward."
