MVME187 RISC
Microcomputer
Module
The MVME187 is a
double-high
VMEmodule
based
on
the MC88000 RISC
microprocessor.
The
MVME187
has
4, 8, 16,
or
32MB of
dynamic
RAM, a SCSI
mass
storage interface, four serial
ports,
a
printer
port,
and
an
Ethernet
transceiver interface. The MVME187
onboard
DRAM is located
on
a
mezzanine
board.
The
main
board
and
the
mezzanine
board
together take one
slot.
Front
Panel
Switches
The
MVME187
module
has
ABORT
and
RESET switches;
and
FAIL, STAT,
RUN, SCON,
LAN,+
12V (LAN
power),
SCSI,
and
VME indicators; all located
on
the
front
panel
of the
module.
When
enabled
by
software,
the
front
panel
ABORT switch generates
an
interrupt
at
a
user-programmable
level.
It
is
normally
used
to
abort
program
execution
and
return
to
the
187Bug
debugger
firmware
located
in
the
MVME187 EPROMs.
The
ABORT switch
interrupter
in
the VMEchip2 is
an
edge-sensitive
interrupter
connected to
the
ABORT switch. This
interrupter
is filtered to
remove
switch bounce.
The
front
panel
RESET
switch
resets all
onboard
devices,
and
drives
SYSRESET*
if
the
board
is
system
controller. The RESET switch
may
be
disabled
by
software.
