Re: "$30: Tang Nano 20K FPGA board"
Now you have me wondering if it's possible to turn a potato into a transistor. While a whole CPU isn't in the cards, maybe a few logic gates for some basic arithmetic is.

@darkghost, what a perfect Make Magazine article!
BTW, a few years back, Make guideline for writers was "Write an article, then write a 300 word review of it, and submit it. Discard the article".
I was always amazed how Make managed to provide zero information...

$30: Tang Nano 20K FPGA board — Time to go back to making potato CPUs with FPGAs. Last time around I've screwed around with a Nano 9K, which was awesome and just fit a 6502 with 48K RAM and a few perifs. The Nano 20K, with the same form factor (the size of my thumb but flatter), is even better for $10 more. It is roughly twice the speed, has 96KB blockram, 64Mb SDRAM and 48 DSP units. And it still has tons of IO pins, HDMI, LCD, USB, audio and microSD connectors. 7 LEDs (including an RGB one)...
