One-of-a-kind 1965 Univac 1830 Computer, Naval Designation CP-823/U. The first Digital 30-Bit computer using DTL (Diode Transistor Logic) silicon microchip flatpack IC\'s. This was the engineering prototype computing system developed and built by Sperry Rand Univac Defense Systems with the US Navy Bureau of Weapons, NADC, Naval Air Development Center, Warminster Pa, for the newly developing P3 Orion, ASW (Anti-Submarine Warfare) aircraft. This historic airborne computer includes development and testing documentation, blueprints, schematics, logic drawings, cables...I have a dedicated website for the Univac 1830. no longer allows linking to outside websites. You can google Univac 1830 or CP-823/U and you will find my site on the first page, P3OrionTopSecret. It does not contain items for sale (except the Univac 1830). It does contain pictures, development and explanations of the Project A-NEW system. Years of developing and testing the Univac 1830 Engineering Prototype in and out of the P3 Orion, led to the repackaged 1830A (CP-901, AN/ASQ-114), which used 27-pin PC cards and began use in the P3C Orion starting in 1969.The Univac 1830 was Univac\'s first complete modular, miniature computing system. The 32,000 word 30-bit memory unit alone weighs 120 pounds, with its seven 4,096 word DRO stacks and one state of the art 4,096 word NDRO Thin Film stack. I am also including a 1959 Friden Flexowriter (if it\'s wanted) as an I/O peripheral that could have been used in the development. Looks good next to it. There is a video of this Friden Flexowriter on my site under the \"more\" link. There was a lot of gold (tested 18k-22k) used in this computer. Hundreds of 4\"x5 1/2\" 90-pin PC cards with gold plated pins, runners and thousands of gold-doped monolithic silicon bipolar DTL IC flat packs. The 90-pin PC cards shown in the picture are spares and were only used in the Univac 1830.There were many ground breaking digital and electrical engineering developments by Univac on this computer, achieving one milestone after another. Expansion of the 30-bit architecture of the NTDS (Naval Tactical Data System) already in use by the US Navy was one. The blinken lights on the control panel were rigged many years ago by another party to execute loops out of the CPU registers, using the repeat instruction/function, ect. With all that is known and written about the development of the digital silicon engine, this is truly one of the first.There are about 12 large pieces to this computing system, weighing 20 to 120 pounds each: 4 airborne I/O units, Ground (laboratory) I/O, 32,000 Word 30-bit Memory, Central Processor, 2 Power Supplies, Control Panel, large box of 90-pin cables, power cables...boxes of documentation, blueprints, schematics...This listing is for local pickup; it can\'t be shipped. Also for this reason, I can not sell internationally. I can hold it for an extended period of time after payment is made. I may be able to transport part of the way. I have added a best offer link for the seriously interested. An offer, if accepted, is a final sale.This is the only engineering prototype of it\'s kind. There was only one Univac 1830. Most of the physical evidence of its existence is included.
