Includes onboard DRAM and EPROM sockets. Designed for real-time control and data processing, it interfaces via the VMEbus backplane for system integration and RS-232 serial ports for console I/O. Common applications include industrial automation, process control, robotics, and telecommunications infrastructure. ## Function A 32-bit VMEbus-based single board computer utilizing the Motorola MC68020 microprocessor and MC68881 floating-point coprocessor, featuring on-board memory expandable up to 4MB, with VMEbus system controller capabilities, four serial I/O ports, triple-interval timers, real-time clock, SCSI bus interface controller, and includes firmware providing debugging, diagnostic, and bootstrapping functions. Designed for high-performance real-time applications in industrial automation, telecommunications, and defense systems. ## Platform Designed for industrial and embedded control applications, this 32-bit single board computer operates within VMEbus (VME64) chassis environments, interfacing via IEEE 1101-compliant front panels and supporting VMEbus protocols. It connects to other VMEbus modules and supports PCI expansion through on-board bridges, enabling integration with PCI carriers. Typical uses include aerospace, defense, and industrial automation systems requiring real-time operation under RTOS such as VxWorks or QNX. Ethernet connectivity and diverse I/O options facilitate networked control and monitoring tasks. ## Application Designed for real-time embedded computing in VMEbus-based industrial, defense, aerospace, and telecommunications systems, this 32-bit single board computer supports high-performance processing tasks, hardware control, and data acquisition. It integrates with VME backplanes via standard VME64 or 2eSST protocols, interfaces with PCI expansion modules, and provides Ethernet connectivity for networked control applications. Typical uses include system control, signal processing, and embedded automation requiring robust, scalable computing in harsh or mission-critical environments. ## Accessories VMEbus chassis and backplane for power/interconnect. Two 96-pin DIN 41612 Type C male connectors (J1, J2) for VMEbus (P1/P2). Two 10-pin (2x5) headers for RS-232 serial I/O (requiring external DB-25/DB-9 cables). Sockets for EPROM (firmware) and DRAM (operational memory) chips. Real-time clock battery. ## Interface Requires a VMEbus chassis with a J1/J2 backplane. Primary system bus connection is via two 96-pin male DIN 41612 connectors (P1/P2) for 32-bit VMEbus data and addressing. On-board I/O is provided by a 26-pin header (J2) for a Centronics parallel port, a 10-pin header (J3) for a configurable RS-232-C/RS-422 serial port, and a 26-pin header (J4) for an RS-232-C serial port. Contains four 28-pin JEDEC sockets for EPROM/SRAM and a socket for an optional MC68881 FPU. ## Images - - - -
