Hi, I just found a scanned/OCR'd copy of "State of the Art" by Stan Augarten on the Smithsonian's website. It covers integrated circuits from their creation right up to the 1980s - the URL is: <http://smithsonianchips.si.edu/augarten/index.htm> Some of the pictures are quite neat, as are a few of the little facts - the origin of ZiLOG's name for one (that's on the Z-80 page). I also came across the "Silicon Zoo" in my Firefox bookmarks list. It's a site full of "chip art" - little doodles that chip designers sneaked into the chip masks. <http://microscopy.fsu.edu/creatures/> There are also a few more on the Chipworks site - URL: <http://www.chipworks.com/gallery/gallery_home.asp> Later. -- Phil. | Acorn Risc PC600 Mk3, SA202, 64MB, 6GB, philpem(a)philpem.me.uk | ViewFinder, 10BaseT Ethernet, 2-slice, http://www.philpem.me.uk/ | 48xCD, ARCINv6c IDE, SCSI ... Let's organize this thing and take all the fun out of it.
