I Am So Nerdy

So, at work the other day, we got another dead iMac for parts from a client, the 24" one there on the right. So now we have ALL THREE sizes of white circa 2006 iMacs! 17", 20", and 24". I was so excited, I put them all next to each-other and took a picture. And yeah, I am nerdy :)

Other Uses of CRT Screens

Did you know that in the 40's CRT tubes were sometimes used as RAM? Strange, but true! I found this fascinating when I stumbled upon it on Wikipedia:

William's Tube on Wikipedia

It would use the photon beam to "write" binary on the phosphors, and then read it back. The charge on the phosphors lasts for a fraction of a second, and you can erase one by writing the block next to it. Hope everyone finds this as cool as I did!

Computer of the Day - IIgs

This computer is one of my most intriguing. It was released in 1986, and was the last Apple II computer. It has no internal HD, like all Apple II's, and I don't have a disk drive for it. It has a 1 or 2.8Mhz processor, and was the first Apple II series computer to feature high performance graphics and sound (Hence, II G S.) It was also the first computer to have ADB (Apple Desktop Bus), that became the standard keyboard/mouse connector on all Macs for over a decade.

Perhaps some clarification is needed. For anyone who isn't aware, here's how it works:

Apple is a company. They produce different lines of products. Their computer line of products is called "Macintosh." Before the Macintosh line of computers came out, the also had the Apple, Apple II and Apple III line of computers. However, they were discontinued in 1992 in favor of the much better Macintosh line of computers. At it turns out, it's improper to say "mac does this" or "mac is a good company" because, of course, "Mac" is just the name of the computers that Apple makes. It is correct to say "Mac Vs. PC" because the computers that Apple makes are called "Macs."

Anyways, on with our computer of the day, and a photo:
