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.

IBM 402 and 403, from 1948, were modernized successors to the 405. Control panel for an IBM 402 Accounting Machine. The 1952 Bull Gamma 3 could be attached to this tabulator or to a card read/punch. [20] [21] IBM 407. Introduced in 1949, the 407 was the mainstay of the IBM unit record product line for almost three decades.
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 ...

Some games, including point-and-click adventures from Sierra On-line and Lucasfilm Games, as well as simulation and strategy titles from Microprose, solved this problem for low-resolution titles by supporting the MCGA's 320 × 200 256-color mode and picking the colors most resembling the EGA 16-color RGB palette, while leaving the other ...
Later, the 407 print mechanism was used in the IBM 1132 line printer, part of the low cost IBM 1130 computer system, introduced in 1965. The IBM World Trade Corporation marketed Computing Accounting Machines (CAM), variations of either the IBM 402 or 407 with an attached computer. CAM variations of the 407 included the IBM 421, 444, and 447. [4]
The Hercules graphics mode is similar to the CGA high-resolution (640 × 200) two-color mode; the video buffer contains a packed-pixel bitmap (eight pixels per byte, one bit per pixel) with the same byte format—including the pixel-to-bit mapping and byte order—as the CGA two-color graphics mode, and the video buffer is also split into ...
