Hi Simon,
No A+G Computerware closed and went to do something else with their lives.
Interface 2 Limited bought their moulding plant and test equipment, and are
starting up where they left off. Alan Stone who runs the company says that
they will have a new website soon with online ordering and
cross-referencing. Meanwhile you can find him at http://www.interface2.com
They also design and manufacure PCB's if you need this.
Hope this helps!
Graham
