Introduction  
This section, when used with the instructions provided 
with the purchased option shows you how to install an 
option in your 
mM 
Portable Personal Computer. 
The procedures for the installation of the Math 
Coprocessor and a second 
mM 
Personal Computer 
Slimline Diskette Drive are difficult. We strongly 
recommend that you have 
mM 
or 
an Authorized 
mM 
Personal Computer Dealer install these options for you. 
If 
you wish to install either of these two options 
yourself, a complete installation procedure 
is 
included 
in this section. Review the "Installation Requirements" 
and the "Tools Required" that follow to make sure you 
have everything you need before you proceed. 
Some of the options that you can install may require 
changes to the switches on the system board 
or 
on 
the 
option.  Switch setting charts are provided at the end of 
the "Installation Procedures" to show which position 
the switches must be set to reflect the addition of the 
option.
