His website was last updated in 2011, according to a notice on the home page. I have tried unsuccessfully to contact him by email on several occasions since he disappeared, though not recently.

I think Kat Manton has also disappeared from view. She and Jim can both be seen on last photo on this page photo, taken at the NVCF in 2006 when we had a large display of vintage TVs:
