Hand-made Web Server, Built From 200 TTL Chips

Posted by Hemos on from the good-stuff-to-do dept.

ps writes "Bill Buzbee has constructed a hand-made CPU, complete with hardware address translation, memory mapped I/O, and DMA, out of 200 74-series TTL chips wired together with thousands of individually wrapped wires. By using a port of Adam Dunkels' uIP TCP/IP stack to the Magic-1, it currently serves up live web pages at an amazing speed of 3 MHz. See the website for photos and schematics."

    Although I'm a software guy, I did get some great advice from folks who actually knew what they were doing. Power/ground & decoupling were given lots of attention, and I was also helped by finding some nice wire-wrap prototype boards that had good power and ground planes. What's keeping Magic-1 from going faster than 3Mhz is my memory access mechanism. I don't support wait states, and rather a lot happens during each clock cycle. In any event, except when being Slashdotted, 3Mhz is plenty fast enough for a homebrew project.
