Disassembling the Workstation 5A
With the LCD/Touchscreen removed, the upper half of Figure 3-5 below,
displays the Workstation 5A base. For comparison, the original Workstation 5
is shown in the lower half of the image.
The Workstation 5A uses the same plastic base, mag card reader assembly, and
speakers as the original Workstation 5. However the chassis, Intel Atom based
System Boards, SO-DIMMs, DMA Enabled CF Riser Card, power supply and
improved power button actuator are new to the Workstation 5A.
