Chapter 3
Disassembly/Assembly
Introduction
This chapter contains all the procedures for the disassembly and reassembly of the PC3x. There
are three main sections: Opening the PC3x, Top Enclosure, and the PC3x Keyboard Assembly.
Warning: If possible, save all user programs and setups before disassembly. For instructions,
refer to Boot Loader in Chapter 4, page 4-2.
Notes, Cautions, Warnings
Please pay special attention to all Notes, Cautions, and Warnings as they not only point out
specific instructions, but also alert you to variations between manufactured units.
Cables, Connectors
Cables
All cables with connectors are keyed, and therefore cannot be reversed.
Warning: Some units may have a small PC board installed on the flat ribbon cable connected to
J202 on the Front Panel Board. Neither the socket nor the pins on this board are keyed. See
page 3-14 and page 3-16 for further information.
Cable Routing
In some cases, tape fastens cables to printed circuit boards or the top and bottom enclosures.
When disconnecting cables, always peel back the tape from one side so that the tape remains
properly positioned.
