The IBM ThinkPad T20 series was a series of notebook computers introduced in May 2000 by IBM as the successor of the 770 series and the first model of the T-series which exists today under Lenovo ownership. Four models were produced, the T20, T21, T22, and T23; [1] the series was succeeded in May 2002 by the ThinkPad T30, but was produced until ...
The IBM Personal Computer, commonly known as the IBM PC, spanned multiple models in its first generation (including the PCjr, the Portable PC, the XT, the AT, the Convertible, and the /370 systems, among others), from 1981 to 1987. It eventually gave way to many splintering product lines after IBM introduced the Personal System/2 in April 1987.
The ThinkPad T30 was released in May 2002, with options for the Intel Mobile Pentium 4-M processor with the Intel 845 MP Mobile Chipset. [7] Additional options included the ATI Mobility Radeon 7500 video controller with 16 MiB graphics memory, a 14.1-inch LCD display with a resolution of 1400 × 1050 , and 1 GiB PC2100 RAM. [ 8 ]
IBM ThinkPad 380E — The 380E model introduced several additional features, along with more optional features available.

Since the rise of the personal computer in the 1980s, IBM and other vendors have created PC-based IBM mainframe-compatible systems which are compatible with the larger IBM mainframe computers. For a period of time PC-based mainframe-compatible systems had a lower price and did not require as much electricity or floor space.
The family comprised the Intel Inboard 386/AT and Intel Inboard 386/PC, which allowed users to upgrade an IBM AT or an IBM PC (or compatible) respectively. The boards allowed users to upgrade their machines' CPU to a 16 MHz 80386 processor. Both variants utilized a ribbon cable which plugged into the computer's original CPU socket on one end ...
TROS was created by IBM as a read-only storage method for storing microcode for IBM computers. TROS used stacks of removable Mylar flexible printed wiring sheets that fitted onto fixed transformer bases. It was used on the IBM System/360 Model 20, IBM System/360 Model 40 and the Type 2841 file control unit. [2]
