If a computer is turned off while disk files are open or while printing/spooling is
occurring, the Student Station(s) affected will show

CAUTION: If the orange Reset button is pressed at a Student Station, that
computer will return to independent operation (that is, it will no longer be a part of
the network). If this happens, the Student Station System Software will have to be
loaded into that Student Station again (following Steps 3 through 10 above) in
order for it to function as part of the network.
To avoid having to re-load the Student Station System Software each day, you may
leave the Student Stations on overnight. (The Network 3 Controller and the Host
computer may be turned off.) As long as a Student Station remains on and the
Reset button is not pressed, the software remains in that computer's memory and
does not need to be re-loaded. If a computer is left on overnight, the screen bright-
ness should be turned
all
the way down (using the brightness control under the left
side of the video display) to prolong the life of the video display.
For instructions on how to print from a Student Station to a printer attached to
the Host system, see Printing and Spooling on page 9 of this manual.
For a list of commands available in Network 3 BASIC (NBASIC), refer to the
Network 3 BASIC Quick Reference section in this manual (page 26). All Model III
BASIC (non-disk) commands are available in NBASIC.
The next section gives an example, using the Radio Shack K-8 Math with Student
Management Program, of how a program with student record-keeping capabilities
runs on the Net work 3 system.
