Selling a vintage 1st generation Amdahl 470 Computer Air Cooled Fujitsu Logic Chip from the 1970's inside a paperweight. This is a very rare paperweight containing an original gold-plated chip. The website chipsetc.com/amdahl.html has a lot of information on these old Amdahl paperweights that contained real chips. This one is the earliest and rarest because it contains the very first air-cooled chip that Amdahl made to compete with IBM's water cooled chips. Amdahl shipped its first computer,the Amdahl 470 V/6, containing this chip in 1975. Here is the information from the chipsetc website:Amdahl 470 Computer Air Cooled Fujitsu Logic Chip
(Mid to Late 1970s)
In the late 70s & 80s the larger IBM mainframe computers were water cooled. Amdahl, an IBM competitor, invented an air coolingtechnology for it's mainframe computers.Gene Amdahl had designed the revolutionary family of 360 computers for IBM, but left the company in 1970 to create a rival organization. For five long years, his company worked feverishly, developing a computer that was faster and less expensive than the IBM System/360mainframe computer systems.The 470V/6, introduced in 1975, was an immediate success. The following year. Amdahl Corporation went public. In the 1970s, when IBM had come to dominate the mainframe industry, Amdahl created plug-compatible computers that could be used with the same hardware and software as Models from IBM, but were more cost-effective. These machines gave IBM some of the little competition it had in that very high-margin computer market segment.During this time savvy IBM customers liked to have Amdahl coffee mugs visible in their offices when IBM salespeople came to visit. While winning about 8% of the mainframe business worldwide, Amdahl won a position of market leader in some regions, most notably Charlotte, North Carolina. In the early to mid-1990's, Amdahl won most of the major contracts for mainframes in the Carolina's.This Lucite paperweight contains an actual Amdahlseries 470 computerlogic chip with an air cooling device mounted on top.The 100 gate logicchip, made by Fujitsu,is fully exposed and the wire-bonding is viewable.The package leads and cooling tower are gold-plated.Amdahl logic chips used Emitter Coupled Logic Technology, which offered speed and performance, but used a lot of electricity which generated a lot of heat that had to be dispersed. The unique cooling tower design that Amdahl engineers came up with allowed the chips to not overheat.Measures 2" x 2" x 2".
