Apple Mac 5260/100 - Manual (Page 7)

Basics Service Strategy - 5
Diagnostics
Use MacTest Pro for Power Macintosh to perform
diagnostics on the Power Macintosh/Performa 5000 series.
Design for Serviceability
To access the floppy drive, CD-ROM drive, or front panel
control board, remove the drive and controls bezel. To
service the logic board, hard drive, or video options, remove
the I/O door. The logic board slides out from a connector
similar to the connector on Macintosh LC 630 and LC 500.
The CRT and degauss frame are matched at the factory and are
removed and replaced as a unit. The chassis harness is one
service module, including the metal chassis and logic board
connector with cables.
