this is a mirror collection of Ken Layton’s files on his old Ken’s Korner site from an archive backup circa 2015. (much of the other links don’t work, so this will have to do) upon his demise some time ago it appears his Google Drive no longer exists. there’s a lot of useful information here and other items are only included for authenticity and historical purposes (like the Zanen lists). I will include some of my alternate links where necessary (like U2000-U5000 service kits where I restored the old bad scan)
