[GreenKeys] [External] Teletype Corp. LSI key fob

[Duncan Brown]

Doug,

Thanks for the info. I did try internet searches, but all I came up with 
was a company called VICON Industries that was involved with video in 
the 1970s, but no obvious connection to Teletype Corp. or Bell System.

Thanks,

Duncan

Also an HP souvenier in the form of an acrylic cube holding the first 32-bit microprocessor.  Under magnification, you can see that both of these souveniers are cast around quality-control reject chips, although the defects are pretty small and don't detract from the chips they display.
