MBus/VPU Processor Modules
Early VPU boards are fitted with standard MBus SPARC modules and two VPU
modules — these plug into the MBus/VPU slots on the MK403 mother board.
Later shipments include a single cache coherent processor board that includes
both the dual VPU processors on a single plug-in board; this board plugs into the
MBus and 2 VPU sockets on the MK403 motherboard. A standard Superscalar
SPARC module plugs into the second MBus slot.
SBus Modules
Three SBus slots are provided and these may be fitted with standard SBus mod-
ules. As with the processor modules SBus modules are simply plugged into the
SBus connectors and secured with 2 screws.
When using SBus cards that have external connections, for example a graphics
card, remove the appropriate panel from the front panel of the MK403 — the
panel is held in place by two small screws. When using SBus SCSI cards the ex-
ternal connections are made via the SCSI connectors on the MK403 front panel.
SBus devices are numbered from 0 to 2, device 0 being next to the processor
slots.
Boot ROM
The boot ROM may be upgraded. It is held in a socket and is easily replaced us-
ing the appropriate tool.
H8 ROM
The H8 ROM may be upgraded from time to time. It is held in a socket and is
easily replaced using the appropriate tool.
