THIS LISTING FOR UNTESTED COLLECTABLE AVIONICL BOARD, IT IS ONE OF MY OWM COLLECTION

tem Description:Up for sale is a magnificent, exceptionally rare vintage aerospace/military-spec analog-digital signal and frequency processing module manufactured circa 1978–1979. This circuit board is a pristine showcase of late-1970s cold-war electronics engineering, displaying ultra-premium component packaging techniques that have long been completely engineered out of modern computing.Densely populated with military 54 series ceramic integrated circuits, hand-wound copper toroidal coils, and gleaming gold architectures, this board serves as a museum-grade technical display piece or an elite industrial décor asset.Key Hardware Highlights:1x Premium Gold-Lid Ceramic Hybrid Module: Stamped RC 64201, featuring a thick, bright gold-plated central sealing lid anchored to a pure white ceramic block.High-Grade 8-Pin Gold Header Cans: Populated with specialized operational amplifiers and transistors featuring fully gold-plated undersides and 8 solid gold-plated interface pins per can.Military-Spec '54' Series Ceramic Logic Matrix: Features premium ceramic CerDIP packages from Motorola, National Semiconductor, and Texas Instruments stamped with authentic 1978/1979 date codes (MC5400L 7902 / DM54121J).Precision Analog Tuning Section: Surrounded by hand-wound copper inductors, silver-cased high-stability capacitors, and a beautifully aligned row of bright-blue multi-turn trim pots.Condition:Outstanding aesthetic and physical condition. The card is 100% factory original, completely uncleaned, un-harvested, and pristine. A gorgeous historical artifact that commands attention on any display shelf. Sold strictly as an obsolete collectible historic display piece.




Technical Breakdown of the Components
This is a stunning Rockwell/Honeywell custom interface array stamped RC 64201 / 821031 / 02927. It is a pure white ceramic substrate capped with a massive, brilliant solid gold-plated hermetic sealing lid. Components from this era with this packaging are famous for containing thick gold-plated inner routing tracks.The 8-Pin Gold-Header Cans (Close-up 3 Matrix): Scattered across the right side of the board are transistor/op-amp metal cans (TO-99/TO-5 footprints). Look closely at their underbellies: the entire bottom header disc is heavily gold-plated, and all 8 pins are solid gold-plated right down into the solder joints to eliminate electrical signal degradation.The 1978–1979 Date Code Verification: The black logic chips across the top right prove the era:DM54121J / 846: A National Semiconductor Military-Spec Monostable Multivibrator in a ceramic CerDIP package. The 54 prefix denotes military temperature compliance, and the J indicates ceramic.MC5400L / 7902: A Motorola military-grade NAND gate manufactured in the 2nd week of 1979.SN54121J / 7910: A Texas Instruments military logic chip from early 1979.The Analog Infrastructure: The card is beautifully built with hand-wound copper coils (toroids) wrapped in protective wire, precision multi-turn bright blue trimming potentiometers, and silver-cased military tantalum capacitors.RARE
