PDP8/S then GRI-909 and the perhaps a british machine called the Molecular?

Many years ago I worked on a minicomputer range manufactured in the UK. The series was the Molecular 18 sold by BCL Ltd. Having an interest in this machine, and in PDP8 machines, I have been looking for links between the two. (The two machines have quite a few similarities) In an interview, Saul Dinman (who designed the PDP8/S) talks about a later design called the GRI-909. Saul had left DEC at this stage I believe. The company that manufactured the early Molecular 18 machines in the UK was Allied Business Computers, who also produced a machine called the GRI-99. This all may be coincidence and fanciful, but does any one have any information of the GRI range of machines? (For more info on the Molecular 18, see www.classiccomputing.co.uk) Kevin Murrell UK
