These conditions can be summarized as follows: o Extended temperature operation o Extended vibration and shock operation o Extended voltage transients operation o Extended particulates operation. The 7531 provides plant floor personnel with a system capable of handling computer applications in the plant floor environment. The 7531 is designed for floor-standing operation. The system unit base is provided with four holes to facilitate optional bolting to the floor or other stable platform. Bolting should be considered only in those situations where placement of the 7531 may affect the stability of the system unit. However, bolting the 7531 is not a requirement for proper operation of the system. The IBM 7531 Industrial Computer is based on a high-performance 16/24-bit Intel 80286 microprocessor, and is equipped with a high-capacity (1.2Mb) diskette drive, keyboard, ROM-based BASIC language, clock/calendar with battery backup, diskette area cover door with security keylock, and system reset button. Standard memory is 512Kb. The system may be further expanded to 640Kb with the 128Kb memory expansion or 128Kb memory board options or up to 3Mb with the 512Kb memory options. The system can be further expanded through additional customer setup options. One or two 20Mb Fixed Disk Drives, a second 1.2Mb High Capacity Diskette Drive, and a Dual-sided (320/360Kb) Diskette Drive are available. A maximum of two diskette drives and one fixed disk drive, or one diskette drive and two fixed disk drives, can be installed in the system unit. These combinations result in direct access storage capacity of up to 41.2Mb. DOS 3.0 supports the 20Mb Fixed Disk Drive and 1.2Mb High Capacity Diskette Drive in the 7531 system. With DOS 3.0, the 1.2Mb diskette drive will also read single- and dual-sided diskettes formatted at 160/180Kb and 320/360Kb capacity, respectively. The Dual-sided Diskette Drive (320/360Kb) option is available for downward diskette portability with the IBM 5531 Industrial Computer and IBM Personal Computers. To fully utilize the 1.2Mb High Capacity Diskette Drive, a new diskette medium is required. The medium is available from the IBM Systems Supplies catalog with the following description: IBM 5.25 Diskette 2HC, double-sided, high capacity, 96 tracks per inch, soft sectored, part number 6109660. To order diskettes, contact IBM Direct, toll-free, via 1 (800) 426-2468. Eight option (feature) slots support feature cards for devices, features, or memory. Six of the slots support either the advanced 16-bit or the 8-bit option cards. Two support 8-bit option cards only. However, the 7531 uses one 16-bit slot for the standard combination fixed disk and diskette drive adapter. The result is seven available expansion slots. A retainer bar is provided to secure the feature cards. A cooling fan is included for the worldwide power supply, and a cooling fan with removable filter for the system unit features. The 7531 also includes a diskette area cover door with security keylock, which, when locked by the user, prevents initialization of the system and entry of command/data from the keyboard. The keyboard offers commonly used data and word processing functions along with separate typewriter and numeric keypads. Key-location enhancements and mode indicators (Cap Lock, Numeric Lock, Scroll Lock) improve keyboard usability. Special symbols may be accessed with a combination of keys. Depending on the application program, from 10 to 40 special function keys may be supported. The keyboard is attached to the 7531 via a 10-foot coiled cable, permitting a variety of workspace configurations.

SECURITY, AUDITABILITY, AND CONTROL The 7531 can be used and managed so as to limit the risk of unintended modification, destruction, or disclosure of sensitive data. User management is responsible for evaluation, selection, and implementation of security features, for administrative procedures, and for appropriate controls in application systems. If sensitive data is sent over external communication facilities, user management may wish to pursue the application of cryptography. PLANNING INFORMATION CUSTOMER RESPONSIBILITY: The customer is responsible for unpacking and installing system components and options in accordance with the installation instructions provided. INSTALLABILITY: The keyboard is plugged directly into the system unit. The display and printer are connected via option adapters installed in the system expansion slots. Once turned on, the system unit automatically runs a power-on self test to verify system readiness. The system unit keylock must be unlocked to complete this self test. If a failure is found, an instruction will appear on the screen. If the test is successfully completed, the system attempts to load an operating system (such as DOS) from the first diskette drive. If that drive does not supply the program, the system tries the first fixed disk. If this operation is not completed, the BASIC Interpreter is made ready, identified on the screen, and the system is available for use.
