Interesting set of rules, with an interesting sense of "purity". In the real world, of course, someone who bought an IMSAI and populated it with only IMSAI peripherals was a fool. And it also leaves out the richness of computing that is (was) possible - take a look in the back of a late 70's BYTE and you'll see hundreds of manufacturers making a huge variety of S-100 boards. Yet any computers demonstrating this richness, so important in the early personal computing industry before the dominance of the PC-clone and the subsequent dull monotony of compatibles, lose points in this proposed judging scheme. Oh well, different strokes for different folks. -- 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
