Ceramic Body 4 Die Green LED

5mm ceramic body green LED, unknown manufacturer, new old stock. These look like a long lost relative of the FLV102; each is constructed on a white ceramic header with gold leads. These LEDs contain for green LED dies, and light output is very good for a LED of this era.

Hewlett Packard 1818 'Zebra' Integrated Circuit

Hewlett Packard 1818-2xxx series integrated circuit, clean condition with minor shelf wear. This chip is packaged in a bizarre square leadless carrier, with a ceramic gray trace base and ceramic cavity lid. As with many of Hewlett Packard's undocumented chips, the function of this device is unknown.

Siemens DL3416

Siemens DL-3416 LED displays, used condition with clean leads, tested and working. The DL-3416 is a larger version of the well known DL2416 smart LED, and contains an entire seven-bit ASCII decoder, character generator, and four-digit alphanumeric display in a single package. This display has its own memory registers, and will remember character data without processor intervention. The 3416 has a package size of 34mm x 21mm.

Unidentified Fiber Optic Component

Unidentified fiber optic component, new old stock, unknown working condition. We are not sure if this is a LED, laser, or a photodiode... the device only passes current in one direction, but does not emit any visible light when power is applied. The top of the device has an unusual water-clear glass rod as it's lens, which strongly suggests that this part is intended for use with fiber optics.

Ceramic Body Red LED

Small ceramic body red LED, unknown manufacturer, new old stock. These LEDs look to follow a similar design methodology as the early Fairchild diodes such as the FLV102; each is constructed from a transistor header that has had one lead removed and the top dipped in red epoxy. The light output from these is brighter than an FLV102 however, and these are easily usable as a normal LED indicator.

MA-COM LD66 8 Watt Laser Diode

MA-COM branded LD-66 pulsed laser diode, new old stock with minor shelf wear.This is a very powerful 904nm infrared laser diode mounted in a gold TO-18 carrier. This diode is designed for pulsed operation, and consumes approximately 12 amps at 1.2 volts when powered on.

Note: these laser diodes are extremely dangerous, and produce invisible laser radiation with enough power to cause instant blindness. The light produced by this laser diode can not be safely viewed without proper eye protection.

White Ceramic 40 Pin Chip Carrier

Gold clad white ceramic chip carrier, 1960s era, salvaged from a semiconductor factory. This carrier still has its leadframe attached, and would be used to produce a 40 pin DIP IC. The holes in the package were designed to mate with plastic screws that would lock the chip into its socket.

Amdahl 209 LSI IC

This is a very rare 209 LSI RAM IC from an Amdahl 5860 'supercomputer' mainframe. Amdahl was known for making air-cooled computers in a market dominated by water cooling, which resulted in their chips having a very unique construction. This chip is no exception, the top is dominated by four tall heatsinks that would have poked into a sort of wind tunnel when installed in a computer. This chip is used, but unlike most loose Amdahl ICs, this chip is not encased in a lucite paperweight, which makes it theoretically possible this part could be used in some sort of very hardcore electronics project. (Good luck finding datasheets though!) This item will be packed in a special foam lined cradle to prevent damage to the fragile pins on the bottom of the chip.
