How to use this Document
& General Info


With the absence of the original host of this document (442.com), my intent is to update and maintain this document at a new home, freely accessible to all (theoldsfaq.com). I have removed certain elements that are no longer relevant as we are now 20+ years on from the last edit. I have also removed some content related to old outdated references which no longer exist. My overall intent is not to modify existing data listed (unless that data is proven to be wrong) - and to provide a good home for this old but useful document.
