If anyone has a .GIF or .JPG of Spock in _The City on the Edge of Forever_ constructing a "primitive mnemonic memory device" from what he terms as "stone knives and bear skins", I'd love to have that to put on my reverse-engineering web page. None of my reverse-engineering aids yet involve a Jacob's ladder or a 3-foot-long breadboard (back when they were really wood!) filled with glowing tubes, but the idea is so appealing that I might try :-). I suspect that for many of us who grew up watching Star Trek, *nothing* is as cool as Spock or Scotty working on a circuit that's throwing sparks. -- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology WWW: http://www.trailing-edge.com/ 7328 Bradley Blvd Voice: 301-767-5917 Bethesda, MD, USA 20817 Fax: 301-767-5927
