There is a ton of information on this Facebook group, with the original CBM engineers commenting a great deal! It is truly an invaluable resource. Not open to the general public, you have to apply to be let in.

An offshoot of this Facebook group is Vintage Computer Stories found at

Actually, it is very Commodore-centric with CBM luminaries writing for it, such as John Feagans, Leonard Tramiel, and Neil Harris. The stories are short and concise from the people who were there at CBM!
