The MVME2603/2604 provides both asynchronous (ports 1 and 2) and
synchronous/asynchronous (ports 3 and 4) serial connections. For the
MVME761-compatible versions of the base board, the asynchronous
interface is implemented with a pair of DB9 connectors (COM1 and COM2)
located on the MVME761 transition module. The pin assignments are
listed in the following table.Serial Ports 3 and 4
For MVME761-compatible versions of the base board, the
synchronous/asynchronous interface for ports 3 and 4 is implemented with
a pair of HD26 connectors (J7 and J8) located on the front panel of the
transition module. The pin assignments for serial ports 3 and 4 are listed in
the following table.Parallel Connector
Both versions of the base board provide parallel I/O connections. For
MVME761-compatible models, the parallel interface is implemented with
an IEEE P1284 36-pin connector (J10) located on the MVME761
transition module. The pin assignments are listed in the following tableEthernet 10BaseT/100BaseTX Connector
The MVME2603/2604 provides both AUI and 10BaseT/100BaseTX LAN
connections. For MVME761-compatible base boards, the LAN interface is
a 10BaseT/100BaseTX connection implemented with a standard RJ-45
socket located on the MVME761 transition module. The pin assignments
are listed in the following table.
For detailed descriptions of the various interconnect signals, consult the
support information documentation package for the MVME2603/2604
SBC or the support information sections of the transition module
documentation as necessary.Overview
The PowerPC debugger, PPCBug, is a powerful evaluation and debugging
tool for systems built around Motorola PowerPC microcomputers.
Facilities are available for loading and executing user programs under
complete operator control for system evaluation.
The PowerPC debugger provides a high degree of functionality and user
friendliness, and yet stresses portability and ease of maintenance. It
achieves good portability and comprehensibility because it was written
entirely in the C programming language, except where necessary to use
assembler functions.
PPCBug includes commands for display and modification of memory,
breakpoint and tracing capabilities, a powerful assembler and disassembler
useful for patching programs, and a "self-test at power-up" feature which
verifies the integrity of the main CPU board.
