the two four track machines he linked together were form ICI from the stories I remember. He designed and built his desk personally long before the standardisation of mixing consoles with optical limiter compressors on every single channel, being the first of its kind built in the UK by years! By the very early 80's Alan had moved onto Apple computers and had no need for his console, which had Neve bits in it lol. As it was built in the room where it was used for many years it could not be simply removed. One day Alan took out all the boards, passed me a pair of snips and told me to cut all wires near the soldered joints, which I did of course and will forever regret, I was only 11 so I've forgiven myself lol. Safely now in smaller bits Alan proceeded to bury it in a field on a mountain top in Mid Wales precisely where I can still remember. I know that he didn't want to sell it, he was a unique man, both determined and self motivated and a sound engineer in the truest sense of the word. The desk I believe often broke down in one way or another so he would get in there and fix it what ever it was and sound engineers today are just not capable of this kind of behaviour!He the last of his kind.
