 It’s easy to get the tools mixed up, but it’s important to know the differences. Quite often (usually by executives) I’m asked the difference between Forums, Blogs, and Social Networks, here’s usually how I explain it (focusing first on usage and benefits rather than technical details):
Forums are like social mixers, where everyone is at equal level, milling about and discussing with others. These many to many communication tools allow anyone to start a topic and anyone to respond to one. Members are often at equal level, and content is usually segmented by topic. (rather than by people).

      Blogs are like a keynote speech where the speaker (blogger) is in control of the discussion, but allows questions and comments from the audience.
Blogs are journals often authored by one individual, and sometimes teams. In the context of business communication, these are often used to talk with the marketplace and to join the conversation that existing external bloggers may be having.

      Social Networks are like topic tables at a conference luncheon. Ever been to a conference where different lunch tables had big white signs inviting people to sit and join others of likeinterest? It’s like that. Social networks allow members to organize around a person’s relationships or interests, rather that just focused on topic. People that know each other (or want to meet each other) will connect by a variety of common interests. These are great tools to get people of like interest to connect to each other and share information.

      It’s important to know the many different tools in your tool chest as every type of accessory fulfills a different need. Before you jump to tools, you should first understand who your community is, where they are, how they use social technologies, and most importantly, what they’re talking about.

Decapping Processors

Article Title: Taking a look at decapped ICs
Author Name: Brian Benchoff

Aside from wanting to play around with nitric acid, [Ben] really didn’t have a reason to decap a few 74xx and 4000-series logic chips. Not that we mind, as he provides a great tutorial at looking at a bare IC that isn’t covered in epoxy and resin.

Most ICs are encased in a hard epoxy shell making it very difficult to look at the circuits within. [Ben] tried to grind this epoxy off with a Dremel tool, but didn’t have much luck until he moved over to a CNC mill to remove 0.040 – 0.050″ of epoxy without breaking the bond wires.

After carving out a nice pocket above the die, [Ben] put a few drops of nitric acid on the chip to dissolve the epoxy coating.  This worked very slowly at room temperature, but after putting the chips on a hot plate the acid was able to reveal the die underneath.

After successfully removing all the epoxy and giving them an acetone bath, [Ben] took his chips over to the microscope and was able to check out the underlying circuit. He doesn’t have any idea what he could do with these decapped logic chips, but the bond wires are still intact so he could still use these chips in a build.

We’d like to see a few decapped MEMS devices, but if you have a suggestion on what [Ben] can do with his decapped chips, drop a note in the comments.

My Favorite Computer: NEC PC-9801

Article Title: NEC PC-9801
Author: Multiple Contributors

PC-98 is a series of 16/32-bit Japanese personal computers, designed by NEC, but also licensed to other companies. In contrast to its PC-88 predecessor, the PC-98 was initially created as a business machine, but over time it eventually became popular with game developers. The PC-98 is based around Intel 8086 and compatible processors, but the design is proprietary, and it is not compatible with the IBM PC or clones, although versions of DOS and Windows were ported to it.

The system has a very large library of video games, consisting of more than 4,000 commercial titles and countless more doujin (indie) titles. The games and system are difficult to find outside of Japan, even on eBay. There are a few sites however that sell the games and systems.

History

When the PC-98 was launched in 1982, it was initially priced at ¥298,000 (about $1400 in 1982 dollars, equivalent to about $3400 in 2012 dollars). The PC-98 computer platform eventually went on to sell more than 18 million units in Japan by 1999, surpassing the Commodore 64 (17 million units) as the best-selling home computer system of the 20th century.

Laptop versions of the PC-9801 were also being sold in the late 1980s. The first was the PC-98 LT, one of the first mass-market laptops. The world's first notebook computer was released in 1989, NEC's UltraLite. By 1990, the 32-bit PC-9801 NC model became the world's first laptop/notebook computer with a colour TFT LCD display.

NEC APC and rivalry with IBM PC in North America
The PC-9801 was initially more advanced than Western computer platforms. In the early 1980s, the PC-98 had already featured a 16-bit CPU, higher VGA display resolutions (initially up to 640x475 pixels, and later up to 1120x750 pixels by 1985) in order to more accurately display Japanese text, Yamaha FM synthesis sound chips for higher-quality audio, and a modem for online internet access.

NEC attempted to introduce the NEC PC-9801 in North America, where it was re-branded as the NEC APC in 1982. NEC, the largest semiconductor company of the 1980s, marketed the APC III as the most powerful computer on the market and more reliable machine than leading competitor IBM's PC platform, with the APC III offering twice as much speed (8 MHz), storage (720 KB floppy disks) and resolution (640x400 pixels) at around the same price. Despite the superior hardware compared to its competitors, the APC III eventually failed to make in impact in North America, largely due to the rise of IBM PC clones, which also negatively impacted IBM's share of the North American PC market.

Rivalry with Sharp X68000 and FM Towns in Japan
The PC-98 was later technically surpassed by fellow Japanese rivals Sharp and Fujitsu when they launched their own more powerful 16/32-bit computers, the Sharp X68000 and FM Towns, in 1987 and 1989, respectively.

In response, the PC-98 began using 32-bit Intel CPU processors from 1987 and supported the CD-ROM format from 1989. While both rival computers were capable of more advanced, arcade quality graphics (especially in the X68000's case) and/or greater multimedia features (in the FM Towns' case), neither computer platform was able to dethrone the PC-98 as the Japanese computer market leader.

3D graphics cards and rivaly with IBM-compatible PC's in Japan
Just as IBM-compatible PC's were on the rise in the mid-1990s, NEC came back by releasing the first 3D graphics accelerator cards on the market, initially for the PC-98. In 1995, NEC released the first 3D graphics card, the PC-FXGA (PC-FX Game Accelerator), exclusively for the PC-98. This allowed the PC-98 to produce the most advanced 3D graphics seen on a home system up until that time, with a polygon rendering performance surpassing the PlayStation console and even rivaling the then upcoming Nintendo 64; in contrast, rival early 1996 3D graphics accelerators for IBM PC clones, such as Creative Labs' 3D Blaster and NVIDIA's NV1, were unable to rival the PlayStation's 3D graphics. The PC-FXGA was originally intended for both the PC-98 computer and the PC-FX console, with as a homebrew development kit for the PC-FX console, allowing the PC-98 to play PC-FX games. However, the PC-FX console lacked the 3D graphical capabilities of the PC-FXGA card, due to the FXGA's HuC6273 graphics chip (originally intended for the PC-FX) never actually being used by the PC-FX console.

The PC-FXGA was the most powerful 3D graphics card on the market up until it was surpassed by NEC's successor, the PowerVR, in early 1996. Unlike the PC-FXGA, the succeeding PowerVR was no longer exclusive to the PC-98, but supported both the PC-98 and IBM-compatible PC's. The PowerVR was able to produce near arcade quality 3D graphics, demonstrated by a near arcade quality port of Namco's Rave Racer, though this PowerVR port was later cancelled. The PowerVR would not be rivaled until the arrival of the 3dfx Voodoo graphics card for IBM-compatible PC's in late 1996. Though both the PowerVR and Voodoo were more or less evenly matched when it came to 3D capabilities, it was the Voodoo that became the most popular graphics card line-up of the late 1990s, due to the PowerVR's lack of third-party software support. Besides the PowerVR, the PC-98 very few other 3D graphics cards supported the PC-98.

Decline
The PC-98 would continue to dominate the Japanese computer market until the late 1990s, when the arrival of Microsoft Windows 95 made it possible for IBM-compatible PC's to accurately output Japanese text, leading to the rise of IBM-compatible PC's in Japan and marking the end of the 'Golden Age' of Japanese computer gaming.

By the end of the 1990s, the PC-98's dwindling market share as well as NEC's greater support for the growing IBM PC market eventually led to the PC-98 slowly losing ground to IBM-compatible PC's. In 1997, the PC-98 NX became one of the first computer platforms produced in line with the PC97 System Design Guide standard, which would later become the worldwide standard for IBM-compatible PC's. As a result, PC-98 standards eventually merged with IBM-compatible PC standards, bringing an end to the traditional PC-98 platform by the early 2000s, succeeded by IBM-compatible PC-98 NX computers which are still manufactured through to the present day.
