Both versions of the base board provide parallel I/O connections. For
MVME712M-compatible base boards, the parallel interface is
implemented with a 36-pin Centronics-type socket connector. The
connector is located on the MVME712M transition module. The MVME2700 provides both AUI and 10BaseT/100BaseTX LAN
connections. For MVME712M-compatible base boards, the LAN interface
is an AUI connection implemented with a DB-15 connector (J6) located on
the MVME712M transition module. MVME761-Compatible Versions
The next tables summarize the pin assignments of connectors specific to
MVME2700 modules that are configured for use with MVME761
transition modules.
VMEbus Connector P2
Two 160-pin connectors (P1 and P2) supply the interface between the
MVME2700 and the VMEbus.
P1 provides power and VME signals for 24-bit addressing and 16-bit data.
Its pin assignments are set by the VMEbus specification.
P2 rows A, C, Z, and D provide power and interface signals to the
MVME761 transition module. P2 row B supplies the MVME2700 with
power, with the upper eight VMEbus address lines, and with an additional
16 VMEbus data lines. Serial Ports 1 and 2
The MVME2700 provides both asynchronous (ports 1 and 2) and
synchronous/asynchronous (ports 3 and 4) serial connections. The
asynchronous interface is implemented with a pair of EIA-574-compliant
DB9 connectors (COM1 and COM2) located on the MVME761 transition
module. 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.For detailed descriptions of the various interconnect signals, consult the
support information documentation package for the MVME2700 single
board computer or the support information sections of the transition
module documentation as necessary.Overview
The PowerPC debugger, PPCBug, is a versatile tool used to evaluate and
debug systems built around Motorola PowerPC microcomputers. Its
primary uses are to test and initialize the system hardware, determine the
hardware configuration, and boot the operating system. Facilities are also
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 these features because it was written entirely in the C
programming language, except where necessary to use assembler
functions.
