Hi Matt,
I assume his old Amstrad email address does not work?
Not when I last tried it some months/years ago. He used to have a site with details of old Amstrad equipment on but that too seems to have gone now. http://web.ukonline.co.uk/cliff.lawson/contact.htm
http://www.our-cottage.co.uk/html/finch.htm is also one of his but there's no contact info there and WHOIS doesn't give an email address.
Perhaps he reads this list's digest and will pop up at the end of the week. :-)
Cheers, Ralph.
