Despite being a year older than Iain, we became good friends, linked through our common skills in computing. He was a wizard with the school's Apple II and helped set up the first few BBC Micros at the school, and he even soldered together his own Acorn Atom machine. I remember him regularly travelling on the bus to computer club at Biggin Hill with a micro in the rucksack and small TV strapped to the top.
I remember too his generosity (and his Mum's) , and I often found myself at Canadian Avenue.
He then followed me to work at Lewisham Sainsbury's and we gradually lost touch after that. I was really saddened to stumble across this site and to hear of his passing. I send my condolences and best wishes to his family.
