Appendix C
Using Your MX-80 With Other Than A TRS-80
This Appendix covers special software considerations when using the MX-80 with
these computers/connections:
A. Apple
B. Pet
C. RS232C Serial Interface
It specifically EXCLUDES hardware considerations, such as how to set the 12
internal switches. That information is supplied in the instruction sets which
accompany the special matching cables and hardware designed to interface with
your computer.
This section includes such things as how the other computers send ASCII codes
down the line if they don't support LPRINT.
APPLE
Install the interfacing card in the Apple per the directions that accompany it.
Since the Apple interface card sends a Line Feed at the end of every line, we
don't need to force one. Accordingly, switches 1-2, 1-3 in the MX-80 should be
ON and switch 2-3 OFF. Double spacing will otherwise result.
Apple computers do not separate the PRINT commands to the screen and to an
external port, such as a printer. The use of either PRINT or LIST will result in
output to only the screen, unless otherwise instructed.
Apple Test and Demo Program
Use this program in place of the one in Chapter 2:
1 0 P R I N T T A B ( 2 3 ) " G R E E T I N G S FROM THE V E R S A T I L E "
2 0 P R I N T T A B ( 3 2 ) C H R $ ( 1 4 ) " M X - 8 0 "
3 0 P R I N T T A B ( 5 7 ) C H R $ ( 1 5 ) " B Y " C H R $ ( 1 4 ) C H R $ ( 2 7 ) " G " " E P S O N "
5 0 P R I N T T A B ( 3 0) C H R $ ( 1 8 ) " Y O U ' L L L I K E M E ! "
6 0 P R I N T C H R $ ( 2 7 ) " H "
but DO NOT RUN IT, YET!
