So I don't spell well at times. Stop being a Jacka@@. Old pal.

In reply to # 1496331 by SpitMan Look up Mathew's old pictures of his car "Born Loser" on his Member page. ( http://www.triumphexp.com/member/Born+Loser )
He had one of those mounted on the front bumper. I have one for mine but have not determined whether or not to put it on.

I do not know where the second part goes or for what but the part with the wires is a Selenium Diode. Used to conduct or rectify current in one direction. Replaced in later years to present with the Silicone Diode.

SILICONE is an elastomeric polymer, used for example as bathtub caulk, or as fill for breast implants.
SILICON is a hard crystalline metallic element, used to fabricate semiconductors such as diodes and transistors.

Good call Calvin on the Honda parts. Flashbacks to my 74 Honda CT70.
Found this pic of battery and diode on the net...

When I think of silicone I remember the original stuff that smelled like vinegar.

Comes from sniffing silicone.

Do you remember the 4004 processor???

In reply to # 1496554 by clshore As an ex-Intel employee, I think of Silicon like this:

I can do better than that.
I worked for a Texas company called Datapoint, that manufactured minicomputer systems whose 8 bit CPU were built up
from hundreds of low and medium level TTL chips soldered onto a 12"x18" circuit board. No microprocessor chips existed at the time.
Datapoint contracted with Intel, whose main IC product at the time was memory chips, to develop a single chip version of
their CPU, to be used in their next generation products, with the obvious advantages of space, power, costs, etc.
The chip was developed and functioned properly, but the problem was chip yield. The size of the new chip was too large
to get enough good ones without defects out of a single wafer to make it economically feasible with the IC fabrication methods of the day.
Fast forward a couple of years, and IC fabrication had advanced enormously. Intel took what they had learned from developing the
Datapoint chip, and came out with their own version, initially the 4-bit 4004, but soon followed by the 8008, then the 8080, 8016, etc, etc.

I mentioned the story a few times while an Intel employee, and got some pretty chilly responses, so I learned to keep it to myself.

Great stuff, Carter. Brings back many memories. To date myself, I find myself fortunate enough to have worked with vacuum tubes, FETs, RTL, DTL, TTL, and on and on. I remember a when a Flip Flop took up a 6" x 6" circuit board......LOL! And don't get me started on memory storage. I thought I had something when I built my first computer: Southwest Technical Products 6800 using a MOT 6800 with a whopping 4K memory! Woo, Hoo! Most guys only had 2K, LOL.

Anyway back to Spitfire stuff not bits to push around there or maybe so. But it was a good walk down memory lane.

I still have my second CPU. No cooling fan needed.
