I appreciate the help so far everyone. I've made a little more progress,
probably passed the internet access challenge, but I still need help.

I had trouble getting compression/image writing utilities on the lab
computers because the executables required internet access. However, I was
able to load the img.xz file onto a Mac in the lab, unarchive the contents,
and write to a SD card using the disk utility.

I booted from the SD card by holding the boot button and verified that I
have the latest version 2018-10-07. I also tested the functionality with
rc_test_drivers, everything PASSED, Robot Control Library Version 1.0.3.

I was able to run the rc_blink program but when I tried to run
rc_test_servos -c 1 -p 0.0, I get the following errors:
ERROR: in rc_pru_shared_mem_ptr could not open /dev/mem: Permission denied
Need to be root to access PRU shared memory
ERROR in rc_servo_init, failed to map shared memory pointer

I tried to change directory to root, but I don't know the password
(temppwd,root,debian don't work). I was also trying to find where these rc
examples were located. I found the rc_project_template here:
/usr/share/robotcontrol/rc_project_template. I'm guessing that the rc
examples are in the root directory or I'm not allowed to see them.
