Block Diagram

RAM200 modules of 16, 32, 64, 128, or 256MB are available for memory expansion. The ECC DRAM is controlled by the Falcon memory controller chip set. The Falcon ASICs perform two-way interleaving, with double-bit error detection and single-bit error correction.

In addition to the ECC DRAM, the RAM200 module supplies 4MB or 8MB of additional soldered-in 64-bit Flash memory. A jumper header (J10) tells the Falcon chip set where in memory to fetch the board reset vector. Depending on the configuration of J10, resets execute either from Flash memory bank A or from bank B.

MVME712M Transition Module

The MVME712M transition module (Figure 1-3 on page 1-16) and P2 adapter board are used in conjunction with the MVME2603/2604 base board.

The features of the MVME712M include:

A parallel printer port (via P2 adapter)

An Ethernet interface supporting AUI connections (via P2 adapter)

Four EIA-232-D multi-protocol serial ports (via P2 adapter)

An SCSI interface (via P2 adapter) for connection to both internal and external devices

Socket-mounted SCSI terminating resistors for end-of-cable or middle-of-cable configurations

Provision for modem connection

Green LED for SCSI terminator power; yellow LED for Ethernet transceiver power

The features of the P2 adapter board include:

A 50-pin connector for SCSI cabling to the MVME712M and/or to other SCSI devices

Socket-mounted SCSI terminating resistors for end-of-cable or middle-of-cable configurations
