IBM 2400 Series Magnetic Tape Unit Tie Bar (1964)
Item #086
IBM 2400 series magnetic tape drives were state of the art technology allowing each 2400' tape reel to store up to 20MB of capacity using 9-track storage at 800bpi (bits per inch).
This was IBM's first 9-track model and the first tape drive capable of recording EBCDIC (8-bit) or ASCII (7-bit) information. These units were used for data storage with the IBM system 360 mainframe computer system.

IBM Standard Modular System - SMS (Late 1950s)
Item #482
This is an SMS card embedded inside a Lucite paperweight. SMS came before the IBM System/360 and its Solid Logic Technology (pre-1964) in the late 1950's when SMS was hot stuff -- this was premiere circuit packaging technology post vacuum tubes and pre integrated circuits (and pre hybrid IC technolgy like the IBM SLT).
The Standard Modular System (SMS) was a system of standard Transistorized circuit boards and mounting racks developed by IBM in the late 1950's, originally for the IBM Model 7030. They were used throughout IBM's second generation computers and peripherals, including its first transistorized calculator the IBM 608.
IBM's SMS technology was superseded by Solid Logic Technology (SLT) introduced with the System/360 Computer in 1964, however they remained in use with legacy computer systems through the 1970s. The vast majority of SMS cards would have been low power logic circuits, forming part of the central processor of the machine they came from.
SMS cards were constructed of individual discrete components mounted on single sided paper-epoxy printed circuit boards. Single width cards were 2.5 inches wide by 4.5 inches tall by 0.056 inches thick, with a 16 pin gold plated edge connector. Double width cards were 5.375 inches wide by 4.5 inches tall, with two 16 pin gold plated edge connectors. An SMS card would typically have 3 to 6 germanium transistors and 15 or so resistors, plus half a dozen capacitors and diodes. A board might contain a flip-flop or a few simple gates, so each board roughly corresponds in function to a Small Scale Integrated (SSI) circuit of the early 1970's.
Some card types could be customized via a "program cap" (a double rail metal jumper bar with 15 connections) that could be cut to change the circuit configuration. Card types with a "program cap" came pre-built for the standard configuration and if a Customer Engineer needed a different configuration in the field he could make additional cuts as needed. This feature was intended to reduce the number of different card types a Customer Engineer had to carry with him to the customer's site.
When SMS was originally developed in 1955, IBM anticipated a set of a couple hundred standard card types would be all that would be needed, making design, manufacture and servicing simpler. Unfortunately that proved far too optimistic as the number of different SMS card types soon grew to well over 2500. Part of the reason for the growth was that multiple digital logic families were implemented (ECL, RTL, DTL, etc.) as well as analog circuits, to meet the requirements of the many different systems the cards were used in.

IBM Direct Access DASD Disk Read/Write HDD Head 3370 (1979)
Item #481
This is a clear Lucite paperweight with actual Disk read/write heads from an IBM 3370 Direct Access Storage Device (DASD). This paperweight was most likely a salesman's demonstration item.
IBM's "New File Project" introduced the IBM 3370 Direct Access Storage Device in January 1979 for use with its IBM model 4331 and 4341 Processors, and for the System/38 mid-range computer. It had seven fixed 14" (360mm) disks, and each unit had a capacity of 571.4 Megabytes. Average seek time was 20 milliseconds and the nominal data rate was 1.859 megabytes per second.
The IBM 3370 was the first Hard Disk Drive (HDD) manufactured that used thin film head technology (Work on thin-film head structures was started in IBM's Thomas J. Watson Research Center in Yorktown Heights, N.Y., in the late-1960s.) The 3370 used a fixed block architecture and was the first HDD to use 2,7 encoding. IBM officially the Model 3370 in august 1986.

IBM 1620 Scientific Computer Transistor and Magnetic Core Memory (1959)
Item #653
This is an IBM clear Lucite paperweight with an actual IBM canned, three-lead transistor and four ferrite (ceramic) core memory "doughnuts" in it.
IBM's model 1620 scientific computer used core memory, as well as some previous IBM computer models throughout the 1950's.
Magnetic Core Memory was an early form of RAM (random access memory) that used very small magnetic rings (known as cores) that were made of ferromagnetic ceramic (Ferrite).
Fine wires are threaded through the cores to enable the cores to reflect a stored value of 0 or 1 depending on the polarity of the magnetic field they are holding.

IBM 1 Megabit DRAM Memory Chip "Mood" Tie Clip (1985)
Item #475
Silver Toned IBM tie Clip showcases an actual IBM 1 Megabit DRAM memory chip embedded inside.
This unique "mood" piece is made of liquid crystals with a protective coating. The crystals respond to changes in temperature by twisting which changes their molecular structure and how they reflect light. The color of this piece changes from blue to green to brown depending on the wearers mood.
From 1984 to 1985, IBM, Toshiba, NEC, Fujitsu, Hitachi and Mitsubishi all announced 1 Megabit DRAM memory chips. IBM's DRAM chip was manufactured using SAMOS (Silicon and Aluminum Metal Oxide Semiconductor) technology.
This IBM computer memory chip, 3/8-inch long, stored more than one million bits of information. IBM was the first to develop and mass-produce chips of this density. At the beginning of 1987, the only such chips operating in the industry were in the IBM 3090, System/38 and System/36 computers and in the IBM 3880 disk "cache" control unit. (VV3131) .
The most powerful IBM computer system of its time, the 3090 high-end processor of the IBM 308X computer series incorporated one-million-bit memory chips.
Although not one of the more well-known mainframe computers, when the IBM 3090 was announced in 1985 it offered a solid advancement on the System/370 architecture that not only continued the improvements in speed, but also increased the number of processors while giving them vector processing options.
Initially only available as Model 200 and Model 400 (the first number denoted the number of processors), the line was expanded dramatically in its short four years of existence. It was replaced by the ES/9000 line.
Measures 2" wide and is stamped on the back with a maker's mark and "IBM".
