General Description

The MVME2603/2604 is a VMEmodule single-board computer
equipped with a PowerPCª 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 systemÑsuch as
synchronous and asynchronous serial ports, parallel port, boot
ROM and DRAM, SCSI, Ethernet, support for an external disk
drive, and keyboard and mouse supportÑin 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
