Remember this?

If I remember correctly, this was a prize at our Liverpool University Amateur Radio Society (G3OUL) dinner one year. I think it was 1969.  It is possible the prize was the successor which was the Micromatic.

When I first came to Cambridge, Sinclair has small premises at 20 Newmarket Road.  

Sir Clive once asked me for advice on antennas!

Talking of G3OUL made me quite nostalgic, so I did some Googling!
