NVRAM
The non-volatile RAM holds system configuration information, environment
variables, and the clock. It is held in a DIL socket and is easily replaced. Note
however that the information within the NVRAM can only be restored by
Meiko’s engineers.
The NVRAM contains lithium batteries which have special handling and dispos-
al requirements — your attention is drawn to the precautions listed in the General
Precautions on page ii.
Fuses
One fuse is used to protect the external keyboard/mouse. This fuse is 250 mA
quick blow, Meiko part number 22–fu400–02e250.
External Connections
External connections are provided for a keyboard/mouse (8 pin circular socket),
RS232 interfaces (2 channels provided by one 25-way D-type connector), and
two independent SCSI buses (each via a 50-way connector). Note that the
MK403 does not include SCSI controllers — the SCSI connectors must be con-
nected to SCSI SBus cards.
Front Panel Connections
Removable panels provide access to connectors on the optional SBus boards.
