Mostek MK4332D-3

The Mostek MK4332D-3 consists of a pair of MK4116E 16kB DRAMs in 18-pin gold-and-ceramic leadless carriers, mounted to an 18-pin ceramic breakout DIP to produce a single 32kB 'RAM-PAK' device. Such hybrid devices were designed to ease adoption of the new leadless carrier technology, by providing a LCC footprint with conventional through-hole pins.

Pacemaker CPU

Hybrid chip intended for use in a medical implant, most likely a pacemaker, as salvaged. These are hybrid chips of a very high construction quality that you would expect from something designed to be implanted in the human body; all of the components have gold leads and even the solder appears to be some sort of gold-based compound. This chip is untested and unlikely to still work; they would serve better in the buyer's electronic oddities collection than inside their chest cavity!.

Western Electric 618 Integrated Circuit

Western Electric 618 integrated circuit, new condition with minor shelf wear. This chip uses an unusual construction style unique to Western Electric; the die has been mounted to the bottom of a white ceramic carrier and covered in resin, which is then inserted into a plastic base. Tabs in the base wrap around the top of the chip carrier and lock the entire assembly together.

SCS 1007CRT

SCS 1007CRT integrated circuit, clean socket pull. The SCS 1007 is an integrated alphanumeric minitron driver IC designed for use with displays like the Wamco KW-105AL. The chip is packaged in an early gray trace ceramic carrier with a gold cavity lid. There is no date code on this chip, but we suspect it was made sometime around 1970.

Unfinished Pentium

This is an unusual device indeed, an Intel Pentium 133 Mobile that has not been mounted into its carrier yet. The die of the chip is mounted to a sheet of Mylar film and then fixed into a plastic chip carrier. Normally these parts would have been trimmed and discarded during the final stages of assembly. These integrated circuits are new old stock.

IRC 7169 Precision Resistor Network

Though it resembles an integrated circuit, the IRC 7169 is actually a military precision resistor network containing 10 high-tolerance printed resistor surfaces. These devices are completely overengineered, with a white ceramic leadless carrier and gold leads, and cost over 30 dollars each back in 1991.
