>># 10 ummmm said,
Dont you mean “DIY”? Or does DYI mean something the rest of us don’t?<<

After that much time, no friends, no wife, no outside fun, no …etc
ergo: DYI= Do Yourself In

Good, maybe he can help GM redesign the Volt.

Either he has a very patient wife, he’s very single or he’s a gay nerd.

Interesting but not amazing…
Allot of hobbiests have done this sort of thing since the 70′s. I have personally known guys who have built machines (computers from scratch Z80, 6502, 8080 etc…) and were fully functional and not just for hobby use, but were used to perform a specific task, these were programmed with CPM… anyhow, the art of this type of ability is slowly dying, everything is micro and nano level so to be able to hold the bits in our hand and build something is simply amazing to some. The Board he used is a prototype card used for the intel Multibus-II. A bus and system not too popular, although it was used by industry for a short while. And these were all stand alone single board computers as well. I myself have designed and built an interface card that had 16bit input and output capability for the old ISA-Slot (my design) from scratch and it was literally thousands of wire wrapped components…but it worked…
Hobbiest of this nature are a dying breed…
Good On Ya mate for building it… but its kinda all been done before…..

#14:

“This is NOT a CPU. hes just used a wirewrap system to link together the actual ICs.
If it were an actual CPU it would not only be somewhat bigger but have thousands of transistors and stuff.”

This is NOT a CPU. It’s just thousands of transistors and stuff. You didn’t design a mask and etch it on a wafer.

This is NOT a CPU. It’s just an etching on a wafer. You didn’t place each atom by hand.

and on and on.

It reads instructions from memory and executes them? It’s a CPU.

#18 & #16 – I never said it wasn’t impressive, just that it wasn’t a CPU.

Follow the link back to the guys blog. This is
a CPU. When was the last time you went to radioshack for a kit and when you opened the
box it said “Instructions : design it yourself”
And no printed circuit. “Here is 100 feet of wire-wrap wire. Knock yourself out.”

Do You Its…. Driving Your Intox….

Hmmmmmmmmmmm. . . .

Oh, of course. The Democratic Youth Initiative, from Croatia.

No wait. What?

“This is NOT a CPU” I think it’s a CPU. Making a CPU from small scale logic is a huge task. Designing an instruction decoder for something resembling a 6502 is a significant project.

I have designed and built many computers from the chip level, a task much less complicated than what this guy did, but even that is orders of magnitude more involved than building a kit from radio shack.

I am reminded of the saying, “If you are not worried, you don’t understand the problem.”

Nice, but this guy built one from TRANSISTORS, no ICs. 3000 transistors.
