Subject : Change of IC701, IC702.
(SPM-03064)
The IC701 and IC702 on the US model have been changed from µPC2581V-S to
STK350-030 in the process of production.
Based on these changes, the MAIN board and VIDEO board are changed and
the STK board is added.
This SER VICE MANUAL SUPPLEMENT-1 only describeds the changes made.
