Xycom XVME-678

Xycom XVME-678 is a VMEbus-based PC/AT processor module designed to provide a standard IBM PC/AT computing environment within VMEbus systems. The following outlines its core features and technical specifications:

1. Processor and Performance

Equipped with a 25 MHz Cyrix 486SLC/e CPU, instruction-set compatible with the 486SX, featuring 1 KB of on-chip cache.
Supports up to 16 MB of DRAM with zero-wait-state interleaved page access. Factory configurations include 0, 1, or 4 MB, expandable to 2, 10, or 16 MB.

2. Bus and Interfaces

Fully compliant VMEbus double-high single-board design, occupying one slot (P1 or P1+P2).
Provides standard PC/AT I/O:
- VGA (P10)
- Serial ports COM1/COM2 (P9, P8)
- Parallel port (JK1)
- Keyboard controller and speaker
- IDE hard-disk interface (P5)
- Floppy-disk controller (P4)
Includes an optional 80387SX math coprocessor socket (U7).

3. BIOS and Software Compatibility

Uses a Quadtel AT-compatible BIOS with a BIOS setup menu; access via <Ctrl+Alt+S>, and soft-key lock via <Ctrl+Alt+L>.
BIOS parameters are stored in battery-backed CMOS, retaining configuration after power loss.
Fully compatible with all standard PC/AT software and operating systems.

4. Mechanical and Power Characteristics

Double-high module with dimensions compliant with VME chassis requirements.
Low-power CMOS design, with an on-board battery to maintain CMOS settings.

5. Optional Expansion

Can be used with the Xycom XVME-955 hard-disk/floppy module, which provides a 3.5-inch IDE hard drive and a 1.44 MB floppy drive within two slots.
Supports an 80387SX coprocessor, additional DRAM expansion, and custom jumper configurations.

6. Typical Applications

Industrial control and data acquisition systems requiring PC/AT software operation on a VMEbus platform.
Embedded computing environments that demand reliable real-time I/O and high-speed bus interconnection.

Summary

The Xycom XVME-678 integrates a complete PC/AT computing platform into the VMEbus, delivering a highly compatible and flexible solution for industrial automation, laboratory instrumentation, and embedded systems. With its 25 MHz Cyrix 486SLC/e processor, optional math coprocessor, and rich set of standard I/O interfaces, it is capable of running traditional PC software while fully leveraging the high-speed data-transfer capabilities of the VMEbus.
