The 402 could read punched cards at a speed of 80 to 150 cards per minute, depending on process options, while printing data at a speed of up to 100 lines per minute. The built-in line printer used 43 alpha-numerical type bars (left-side) and 45 numerical type bars (right-side, shorter bars) to print a total of 88 positions across a line of a report.
This article provides a list of widget toolkits (also known as GUI frameworks), used to construct the graphical user interface (GUI) of programs, organized by their relationships with various operating systems.
The first Java GUI toolkit was the Abstract Window Toolkit (AWT), introduced with Java Development Kit (JDK) 1.0 as one component of Sun Microsystems' Java platform. The original AWT was a simple Java wrapper library around native (operating system-supplied) widgets such as menus, windows, and buttons.
An IBM tabulating machine, such as the 402 or 407 series would have several counters available in different sizes. (For example, the IBM 402/403 had four sets each of 2, 4, 6 and 8 digit counters, labeled 2A, 2B, 2C, 2D, 4A, 4B etc.) Each counter had two counter control entries to specify either addition (plus) or subtraction (minus). If ...
This is a list of notable library packages implementing a graphical user interface (GUI) platform-independent GUI library (PIGUI). These can be used to develop software that can be ported to multiple computing platforms with no change to its source code.
VisualAge for Java is based on an extended Smalltalk virtual machine which executes both Smalltalk and Java byte codes. Java natives were actually implemented in Smalltalk. [6] VisualAge Micro Edition, which supports development of embedded Java applications and cross system development, is a reimplementation of the IDE in Java.
The Bull Gamma 3 calculator could be attached to tabulating machines, unlike the stand-alone IBM calculators.

IBM wanted a standard way to interact with text-based user interface software, whether the screen was a dumb terminal connected to a mainframe or a PS/2 with VGA graphics. [1] CUA was a detailed specification and set strict rules about how applications should look and function.
