Have to give some credit for Steve Chamberlin who builded computer that is based on his own build BMOW-processor.
Big Mess o’ Wires BMOW Project Summary

* Current clock speed is 2MHz. It could theoretically go to about 3MHz (untested).
* 512 KBytes of RAM, 512 KBytes of ROM.
* Power draw is 10 Watts, 2.0A at 5V.
* VGA video output is 512×480 with two colors, or 128×240 with 256 colors.
* Audio and music is provided by a three-voice programmable sound generator.
* Keyboard input is a standard PC keyboard with PS/2 connector.
* Debug display is a 24×2 character text LCD.
* There are roughly 1250 wires connecting the components, so 2500 individual hand-turned wire wraps.

Wah 2500 hand-turned wire wrap...I salute u!

First of all, 100 wire wraps on development board already can cause mistakes.

Secondly, it certainly 100x the project we do for computer engineers, with so much complexity in wiring schematic.

Wonder if there can be HDD wire to it? Or only just ROM written game be play.

Power draw is 10 Watts, 2.0A at 5V. This is really ideal for power consumption... high end com can never reach this due to high GPU consumption.

ENDED with CLAPS, CLAPS and

Wow... I am currently studying DLX processing machine and was struggling with it. And this guy made a processor with ALU and registers along with memory...
