My Home-Built TTL Computer Processor

Wow, a webring widget at the bottom. That's been a while.

Here is another home-built CPU made from 74HC (TTL-compatible CMOS) integrated circuits:<p><a href="http:&#x2F;&#x2F;www.mycpu.eu&#x2F;" rel="nofollow">http:&#x2F;&#x2F;www.mycpu.eu&#x2F;</a><p>The author gave a talk about it in our local hackerspace back in 2009. Fascinating stuff.<p><a href="http:&#x2F;&#x2F;video.kiberpipa.org&#x2F;pot_mycpu_dennis_kuschel&#x2F;?q=mycpu" rel="nofollow">http:&#x2F;&#x2F;video.kiberpipa.org&#x2F;pot_mycpu_dennis_kuschel&#x2F;?q=mycpu</a>

This reminds me of the Duo Adept[1], a full TTL computer with video output, keyboard input and a homebrew operating system. All built by a teenager in his spare time.<p>1: <a href="https:&#x2F;&#x2F;m.youtube.com&#x2F;watch?v=qYvr0b8jqbg" rel="nofollow">https:&#x2F;&#x2F;m.youtube.com&#x2F;watch?v=qYvr0b8jqbg</a>

This is something I still have on my bucket list. I remember as a kid looking at the electronics catalogue eyeing the z80 chip thinking to myself &quot;I&#x27;m gonna build a gameboy!!1&quot; because my friend had a gameboy and I wanted to join in on the pokemon fun!

I was also thinking of constructing a CPU in this fashion using the ideas from Mill CPU folks.<p>I will probably never have enough time to go through this, which is sad.

Wow ... remember when &quot;build a computer&quot; didn&#x27;t mean &quot;order a motherboard and a disk drive, and make sure you get the right size power supply.&quot;

Very cool. Reminds me of _The Soul of a New Machine_, with all the painstakingly assembled discrete logic.
