Several years ago he built first �Magic-1� processors , but now he makes its documentations widely available in his project website. http://www.embedds.com/how-hard-is-to-build-a-processor/ Cheers Don... -- Don McKenzie Site Map: http://www.dontronics.com/sitemap E-Mail Contact Page: http://www.dontronics.com/email Web Camera Page: http://www.dontronics.com/webcam No More Damn Spam: http://www.dontronics.com/spam Product Sellout: 15% OFF 4DSystems OLED Displays & modules. http://www.dontronics-shop.com/micro-oled.html

Someone should be keeping the old craft alive. Good on him ! You could ask 'why build museums' ? I think you agree.

Thanks, Don. I absolutely LOVE doing this kind of thing. It should be required work for anyone in embedded programming, at least. 35 years ago I tried my hand at it and failed to get much useful. It wasn't until I later got access to a logic simulator that I was finally able to complete a successful processor design with 7400 logic, not using the 74181 ALU by the way, though I never built what seemed to work so well. Later, I picked up a Xilinx 4000 series demo board and, for the very first time, learned to write VHDL and finally coded up my first processor that worked!!! (I didn't do the floorplanning by hand -- way over my head at the time.) I learned so much doing this, though. Anyway, thanks for the link!! Jon

Reminds me of the pdp11 look alike I worked on back in the early 70's... few hundred ttl chips , 64 bit diode matrix microcode, 8K ferrite sotore driven by loys of monostables to get the timing right.... I was used to poser some of the very first CNC machines in the UK- Herbert BatchMAtic and in Germany - Boehringer Vxxx series lathes. Those were the happy days......

They really made it work though I doubt any subscriber built it too. petrus bitbyter |
