Yes, I have been there, done that. Even wrote.
True, there are a few files I have not finished examining.
Thanks for reminding me. I will visit there today.
Still, it looks like most of my questions remain

PLUS I would still like to pick up somewhere an empty
Centennial POP box with the instructions and interleaving
paper still inside... not just for the reading, but I
actually want to have them.
Thanks,
Ray
