DESCRIPTION The newly announced model of the IBM 7531 and 7532 Industrial Computers provides increased performance for industrial applications, including IBM network functions and workstation emulation capabilities. The new model is based on the high-performance 16-bit Intel (R) 80286 Microprocessor. This model also includes the BASIC language and clock/calendar with battery backup. The Model 111 system unit includes 512KB of standard memory, a single 1.2MB high-capacity 5.25-inch diskette drive, a combination fixed disk and diskette drive adapter, and a 20MB fixed disk drive. 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 Model 111 use 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. 3.5-INCH 720KB DISKETTE DRIVE (#6163) This feature is a half-high, double-sided 3.5-inch diskette drive supporting the 3.5-inch media with 720KB storage capacity. The option provides data transfer between 5.25-inch and 3.5-inch media, allowing greater compatibility with other IBM equipment. The drive uses the combination fixed-disk and diskette drive adapter, standard on the 7531 and 7532. The drive requires the IBM Disk Operating System (DOS) Version 3.2, or later, and must be installed as Drive B of the system unit. With unlike diskette drives installed, special considerations are necessary if a backup copy or working copy of 5.25-inch diskettes is required. The backup or working copy will be on a 3.5-inch diskette that cannot be used in the 5.25-inch diskette Drive A. 128/640KB MEMORY EXPANSION OPTION (#3338) This Memory Expansion Option comes with 128KB of memory. With the addition of the 512KB Memory Module Kit (#3339), this option can be expanded to 640KB.

ADVANCED 3278/79 EMULATION ADAPTER (#5050) The Advanced 3278/79 Emulation Adapter is a circuit card that plugs into any one of the expansion slots in the IBM Industrial Computer System Unit. A cable receptacle mounted on the card provides for attachment of a customer-supplied coaxial cable, IBM Cabling System media (3274 attachment only), or telephone twisted-pair via IBM/ROLM Coax-to-Twisted-Pair Adapter at the rear of the system unit. Most, but not all, functions of the emulated displays are supported. The Advanced 3278/79 Emulation Adapter provides host communications support via 3278/79 emulation. When used with the IBM PC 3270 Emulation Program Entry Level or IBM equivalent, the Industrial Computer can emulate the functions of an IBM 3278 Display Station Model 2 or an IBM 3279 Color Display Station Model 2A or S2A with certain restrictions and can support file transfer with certain host systems. Both the host-controlled 3270 session and a local IBM Disk Operating System (DOS) session can be active concurrently and the user can interact with either session alternatively. The 3270-PC File Transfer Program (5664-281 for Virtual Machine/System Product (VM/SP), 5665-311 VSE/SP 2.1.1, 2.1.2, or SSX/VSE 1.4.1, or IBM equivalent) is required for file transfer. File transfer to the 4700 system is not supported. The following are additional highlights of the Advanced 3278/79 Emulation Adapter: o Distributed function terminal mode operation allows distribution of 3270 data stream processing from the control unit to the Industrial Computer and allows implementation of advanced capabilities such as multiple concurrent 3270 sessions. It requires corresponding capability in the upstream node (available with the IBM 3274 Control Unit) and in an IBM Personal Computer 3270 Emulation program (available with 3270-PC Control Program). Additional information is available in the IBM Personal Computer 3278/79 Emulation Adapter Technical Reference for the Advanced Adapter. o Low power usage o Attachment of the IBM Industrial Computer to: - IBM 3274 Control Unit - IBM 4321 Processor Display/Printer Adapter - IBM 4331 Processor Display/Printer Adapter - IBM 4361 Processor Display/Printer Adapter - IBM 4701 Finance Communication Controller o No host hardware or host system software modifications required for 3270 emulated functions. o Supports attachment to the IBM 3274 via the IBM 3299 Terminal Multiplexer.

AT/370 OPTION KIT (#6115) This option, along with VM/PC 1.1, allows the IBM 7531 and 7532 Industrial Computers to be a System/370 workstation. An IBM 3278/79 Emulation Adapter (#5050) may be installed with this AT/370 Option Kit in the system unit for a host 3278/79 session and data transfer. Highlights of the AT/370 Option Kit and VM/PC 1.1 are: o Support of unique concurrent sessions via hot key: - Local System/370 CMS session - Host 3278/79 session via an optional 3278/79 Emulation Adapter that will provide a coaxial connection to an: -- IBM 3274 Control Unit -- IBM 4321/4331/4361 Processor via a Display/Printer Adapter -- IBM 4361 Processor via a Work Station Adapter -- IBM 4701 Finance Communication Controller via a Device Cluster Adapter (host server functions not supported) - Remote 3101 emulation session with IBM Personal Computer 3101 Emulation licensed program (6024042) and serial/parallel adapter installed - System/370 Processor Control Session o Ability to execute many unaltered host System/370 VM/CMS programs o Hardware relocate to support up to 8MB virtual addressing o IBM 7531 and 7532 Industrial Computers functional capabilities unchanged after this option kit is installed. The AT/370 Option Kit consists of two (PC/370-P2 and PC/370-M2) cards that allow the IBM 7531 and 7532 Industrial Computers to execute many of the System/370 instructions. The PC/370-P2 card consists of three microprocessors, a page table and attendant circuitry. The first microprocessor executes most of the commonly used fixed point System/370 instructions. It performs all instruction fetches and decoding and all effective address calculations. The general purpose registers (GPR) and program status word (PSW) are kept in this microprocessor. The second microprocessor emulates the remaining non-floating point System/370 instructions, interprets the diagnose instruction, manipulates the page table, handles exceptional conditions, and performs hardware housekeeping as required. The third microprocessor executes System/370 floating point instructions. The floating point registers are kept in this microprocessor. The page table consists of two static RAM devices arranged in a 2048 x 12 array. Each virtual page is assigned to an entry in the page table. Each entry contains its real page number and status bits. The PC/370-M2 card contains 512KB of parity checked RAM accessible from either the PC/370-P2 card or the microprocessor for the IBM 7531 and 7532 Industrial Computers. Concurrent requests for memory accesses are arbitrated. This memory (512KB) is viewed in native mode as a 128KB storage area that begins at the end of the 512KB of required memory in the IBM 7531 and 7532 Industrial Computers. The PC/370-P2 card views the 512KB memory as two separate areas which are not contiguously addressable. The area from zero to 480KB is addressed from zero to 480KB and is real System/370 space. The area from 480KB to 512KB is addressed from zero to 32KB and is control store for the second microprocessor on the PC/370-P2 card.
