    5.   Meyers Lab 1.3

         a)  Take cover off PC. Locate CPU chip.
               Is fan attached?   ________, is it easy to remove _______?

         b)  What kind of CPU is it                                         __________?

         c)    What kind of RAM does your PC have (SIMMS or DIMMS) _______?

         d)   How many and what kind of expansion slots are in your PC


          e)  How many and what kind of cards are in the expansion slots?


          f) Trace the wires that go from your power supply to the motherboard and to the floppy,  CDROM, and hard drive?

          g) Carefully disconnect and reconnect each device's cable (one at a time, in
               sequence, don't get confused).    See whether the cable will go on backward.
              (Don't force it, if it  won't go,)

          h)  Can you see any ways to make sure you connect the cables the right way?


          i)   See if you can locate any jumpers or DIP switches on your motherboard, but
