Here is a request for help; I have found a bunch of rails of *old*
chips kicking around.  I am curious what they are, but my databooks
are all packed up...  Here is the list if anyone out there has some
old books available and wants to take a moment to look them up and
send me the results (I will post them to the list, just so people 
can see how old this junk *really* is).

Thanks in advance!
