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
