4.2.8 Memory Module Removal
There are three memory modules available; 4 Mbyte, 12 Mbyte, and 16 Mbyte
modules. The 4 Mbyte and 12 Mbytes modules are physically the same. The
16 Mbyte module is slightly larger than the other two and it contains two
additional connectors for connecting one of the other two memory modules
piggyback style. This piggyback connection allows the 4 Mbyte and 12 Mbyte
modules to increase the total memory in the system to 24 Mbyte and 32
Mbyte (including 4Mbyte on the system module). Removal procedures for
all memory modules are the same. However, you must separate the memory
modules if the 16 Mbyte module has a memory module piggybacked on it
and replace the faulty module.
1. Remove the system box cover (Section 4.2.1 ).
2. Remove the drive mounting panel (Section 4.2.2).
