Performing the Upgrade

and from IDE to SCSI.
Before You Start the Upgrade
!
WARNING :
Observe proper electrostatic discharge precautions when handling computer
components. Wear a ground strap against your bare skin and connect to an
earth ground.
Gather the appropriate tools, the components of the upgrade kit, and a space to
place the old components you remove from the MAP/40 (hint: have an empty box
to place old components in to avoid mixing them in with the new kit components).
Upgrading the MAP/40 Hardware
Use the following procedures to upgrade your CPU card, hard disk drive system,
and install the RMB card. These procedures are separated into sections that are
meaningful if perform sequentially, but with experience, you can save time by per-
forming some sections simultaneously.
