Another wave of new items have been added to the website * Solid State Indicators: Three new vintage LEDs, including a very early green model. |

| 2008-06-03 The Internet is a Series of Tubes! | |
| Posted by AnubisTTP |
We have added several new scientific apparatus to the Gas Discharge Tubes section: a Crookes cathode ray tube and two spectrum tubes that appear mundane in function, but are constructed with very unusual envelopes. Other new tubes to appear on the site are the General Electric GL-6452 x-band reference cavity and the uranium-doped Eimac CIM-481274 vacuum capacitor. Not every new item to appear in this update is a tube however. We have added a vintage and strange Motorola LED, which is packaged in a red epoxy TO-92 case, to the Solid State Indicators section. |

Hamvention 2008 was pretty weak. Vendor attendance was significantly lower than in recent years, and I have a special *go to hell* saved for all of the gold scrappers out there who, within a two year span, have made it virtually impossible to find affordable used HP test equipment or gold-on-ceramic IC chips. Screw you and your ilk, you are destroyers of history and a cancer on society. You should try something more dignified and appropriate to your regressive species, like stealing the copper mains out of abandoned buildings and selling them for meth money. |

| Posted by Accutron |
Well, Dayton Hamvention 2008 is impending, which means we're pretty busy gearing up for it, but we've managed to add a few new items in the past week, including some argon laser tubes and a couple new microwave oscillator tubes. We've also added the Hamamatsu R444 circular-cage PMT, one of the smallest of such devices ever constructed. |

Okay, I admit that we've been wrapped up in some definitively non-vintage technology lately. We've been building a couple projects using some extremely modern Lamina Ceramics RGB light engines. They may not be old, but they are very, very bright. |

| Posted by AnubisTTP |
We have added several new LEDs to the Solid State Indicators section, all of which feature metal can style packages. The TLMP 9210, TLMP 9310, and TLMP 9710 are a series of nearly modern, hermetically sealed LEDs which use a metal TO-46 package. The Soviet-made 3L341 is a green metal and epoxy packaged LED that was manufactured shortly before the fall of the Soviet Union. We have also added a very rare Monsanto MDA-111 display module, an integrated character generator and driver for the Monsanto MAN-2 bitmapped LED display. |

| 2008-03-19 New Items | |
| Posted by AnubisTTP |
We have added several unusual new items to the site over the past few weeks. The Burroughs SD-11 is a sphericular optical display, a niche numeric display device that may look like a projection display, but does not function even remotely like one. ETL's GS12C is one of the most unusual dekatrons that the company ever made, a base 12 selector with a rare 'maintenance' style base, which has lugs instead of pins for easy direct connection of wire leads. We have also added a number of Western Electric integrated circuits to the Solid State Logic section. |

| 2008-02-28 Your PC Asplode | |
| Posted by Accutron |
Well, early last week I finally lost a hard-fought battle against a very nasty malware package, and our main business PC went down, hard. This thing has worked itself into the boot sector on my hard drive, and due to the logistics of daily life it probably won't be fixed for a couple more days. |

| 2008-02-19 Day of the Diode | |
| Posted by AnubisTTP |
The assault of new components continues, we have added two new diodes to the newly splintered Solid State Indicators section, a Western Electric Trimline 220 Series LED and a slightly humorus green epoxy diode with a red GaAs die trapped inside. We have also added a 0Z4G tube to the Gas Filled Rectifiers section and a CV359 bargraph indicator to the Variable Indicator Tubes section. Be sure to also take a look at Tiny Tetris, one of the smallest electroinc Tetris games ever made. |

| 2008-02-14 SiC Blue | |
| Posted by Accutron |
Twenty years ago, engineers and hobbyists alike told tales of the mythical blue LED, the Kwisatz Haderach of LEDs. Silicon carbide (SiC) devices had existed in the lab for decades, but were too dim for practical use. SiC eventually made it to production, only to be quickly swept aside by the development of indium gallium nitride (InGaN) devices. InGaN LEDs are now available in any color from green to ultraviolet, and are anywhere from 100 to 1000 times brighter than SiC. SiC is no longer produced as a primary die material, only as a substrate for InGaN devices. |

| 2008-02-07 Miscellaneous Bits | |
| Posted by Accutron |
Several new devices have been added, including three new Burroughs beam switching tubes: the JAN-CBSC-6700, BD-316 and BX-2004. We've also added an extremely unusual SCM Marchant M1 LSI calculator chipset to the Digital Integrated Circuits section. The M1 chipset was built by TI and AMI, and makes use of a primitive ceramic leadless carrier, possibly the first LCC ever constructed. No other ICs are known to have this carrier style. |

| 2008-01-29 Reorganization | |
| Posted by Accutron |
The site has received a fairly major series of updates over the past week. Some articles have been moved, removed or reorganized for various reasons. The section headers in the top bar are a bit different. Component Devices and the relevant portion of the Instrumentation Museum have been combined into a singular Electronics Museum, and we have added headers linking to our pre-existing YouTube channel and eBay store. We believe the changes make the site more concise, relevant and easy to navigate. |

| 2008-01-25 The Shirt | |
| Posted by Accutron |
Are you the biggest nerd in your social group? Do you get tired of explaining the importance of internal spade resistors to your less geeky friends?
We have the solution, send them to our site with an awesome Burroughs MO-10R shirt, designed by world-class graphic artist Stephen Ritchie. This is
an extremely high quality shirt, and photographs definitely don't do it justice. The artistic detail and print quality are absolutely unmatched. |

| 2008-01-21 New Hybrids | |
| Posted by Accutron |
We've added several new HP parts to the Digital Integrated Circuits section, most notably the rare 5061-3010 and 5061-3001 hybrid microprocessors. The -3010 is the original 82-pin hybrid designed for the HP 9825A, while the -3001 is an advanced 107-pin variant which adds an Address Extension Chip. Combined with the -3011 microcode variant previously documented, this completes the series of known production hybrid microprocessors. |

We have added three more dekatrons to the Glow Transfer Counting Tubes section: the GC12/4B, GC10D and GC10/4C. The GC12/4B may look like a normal Ericsson dekatron, but it has unusual internal function. Unlike most dekatrons, the GC12D has the ability to perform base-12 counting instead of base-10. The GC10D is one of the few British argon-filled dekatrons, and is even more noteworthy because it still contains its original gas. The GC10/4C is a standard neon bidirectional counter, but has a unique compact envelope and base that separates it from its more common 'B' suffixed brothers. |
