I guess it's like everything vccomm use up all the old parts first before using the new ones.
My documents show from a Technical bulletin that the LM was introduced in November 1978.
So I'm guessing that the older bits could still have been used,after all from a business scene it would be silly just to throw out parts that can still be used.This is making me want to count how many G4's I need and ask if anybody has any.I should as I know I'm short on them.
