@tom-ii :

 

Sorry your schematic is lost. Thank you for looking, nonetheless :)

Update:

 

Took a look in the only places it might be..  It appears to be lost to the annals of time.  Interesting thought, though,, maybe someday I'll rebuild it on an FPGA...

Oh, holy cow.  That was a long time ago.  I'll take a look, but I won't hold much of a whisper of hope...

I once built a 4-bit CPU from 7400 logic on a few breadboards - it had a whopping 256B of RAM!

Could you post schematics somewhere?  I can't be the only one that would be intrigued by something like this.

build the circuit using 74LS-series logic. (Does anyone still do this?)

I guess sometimes we do it, even if for just plain saudosism :)

Here's something I came up for the 2011 7400 competition :

The contest is (was?) organized by Dangerous Prototypes, and many interesting stuff has popped up in 2011 and 2012. There was no contest in 2013 as far as I know, perhaps this year.

It was so fun...

@Tom-ii: ...but the most gloriously Magnificent Max suggested that I write something out and present it to the EE Times universe for your amusement.

Oh, so now it's my fault! LOL

LATEST ARCHIVED BROADCAST
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
