General Micro Systems' Pentium III-based VMEbus CPU board serves as a drop-in replacement for legacy 68040, 68060, and PowerPC VMEbus boards running the VxWorks OS.

The V160 Liberty is said to run VxWorks applications 250 percent faster than predecessors and, at $1,200, to be about half the price of its fastest competitors. In spite of the price differential, General Micro said that the V160 also adds functionality, such as an extra Ethernet port, two PMC extension ports, two additional serial ports, and an IDE interface.

The V160 is based on the Pentium III/Celeron processors and the 440GX chipset. It provides a full 64-bit VME64 interface using the Tundra Universe II device, and can function as a VMEbus master, slave, or system controller.

Featuring a maximum clock of 1GHz, the V160 is equipped with up to 1GB of main memory (upgradeable to 2GB) and 256KB of on-die Level 2 cache. It also features two 10/100Base-Tx Ethernet channels, an Ultrawide SCSI interface and two PMC ports that support up to five PMC expansion cards.

The board supports all the legacy I/O functions needed to run Windows and VxWorks out of the box, General Micro said, including four serial I/O ports; two USB ports; floppy, mouse and keyboard ports; and four 32-bit timers.

Its two IDE DMA-33 ports support rotating media drives up to 100GB or Flash drives up to 20 GB, all within a single VMEbus slot. Other system I/O features include optional Compact Flash, 4MB of system BIOS/user Flash, 256 bytes of serial EEPROM (for VxWorks boot parameters), up to 16MB of optional bootable Disk On Chip Flash and up to 8KB of battery-backed NVRAM.

The board runs Windows NT and 2000, VxWorks, Solaris x86, and Linux. It also runs NT Embedded, including the deterministic real-time extensions offered by Venturecom.

Prices start at $1,195 for a single board equipped with an 850MHz Celeron and 64MB of SODIMM SDRAM.
