Are you talking about the way some started coming with no window in the 
package?  I've run across *one* of those so far.  Lots of the usual kind,  
though.

I also happen to have a few 1702s.  No intentions of using them because of the 
oddball power supply requirements,  but they sure are pretty,  in those white 
ceramic and gold packages.  :-)

I suppose if somebody wanted some of these I could be persuaded to part with 
some...

I also do have a programmer,  but I don't think it does those,  or anything 
earlier than the 2716.
