General Description

The MVME2603/2604 is a VME module single board computer equipped with a PowerPC Series microprocessor. The MVME2603 is equipped with a PowerPC 603 microprocessor; the MVME2604 has a PowerPC 604.

256KB L2 cache (level 2 secondary cache memory) is available as an option on all versions.

As shown in the Features section, The MVME2603/2604 offers many standard features desirable in a computer system—such as synchronous and asynchronous serial ports, parallel port, boot ROM and DRAM, SCSI, Ethernet, support for an external disk drive, and keyboard and mouse support—in a single-slot VME package. Its flexible mezzanine architecture allows relatively easy upgrades in memory and functionality.

A key feature of the MVME2603/2604 family is the PCI (Peripheral Component Interconnect) bus. In addition to the on-board local bus peripherals, the PCI bus supports an industry-standard mezzanine interface, IEEE P1386.1 PMC (PCI Mezzanine Card). PMC modules offer a variety of possibilities for I/O expansion through FDDI (Fiber Distributed Data Interface), ATM (Asynchronous Transfer Mode), graphics, Ethernet, or SCSI ports. The base board supports PMC front panel I/O. There is also provision for additional expansion via a PMC carrier board.
