Multiply the above numbers by a factors of 1.5 or so, and you're about in the right ballpark (though the real factor is much closer to 4 for the power supply - $50 won't buy anything but a way-too-dinky transformer.) I did a similar calculation when deciding whether I could sell my "TIMSAI" as a commercial product, and came up with a street price for it (with very similar production costs) that would have to be close to $2000-$3000 to justify the effort. -- 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
