Sony VAIO mainboard documentation for MBX-160, packed in a 1.21 MB RAR archive, with the code MS70 and R2.0 / R2 revision markings in the name. MBX numbers are Sony own mainboard designations, while the MS70 code relates to the ODM project name used in the drawings. The package is suited to tracing power rails, charger and sequencing signals and locating components. Confirm the MBX-160 label and revision on the board match R2.0 before using values from these sheets.
