ATARI800/400
The Interface
The best way to hook up your Atari to your Gemini is with the
Universal/Atari Parallel Interface by Star Micronics. It comes
complete with its own cable. You may also use an Atari 850 inter-
face; pin-outs to build a cable for the 850 are listed in this Appen-
dix.
Setting the DIP Switches
Turn DIP switch number 2-3 and 2-4 "off" on your Gemini, and posi-
tion switch number 2-1 as you wish.
DIP switch number 2-2 shold be set "off" if you want Gemini
to print every time it receives a CR code; set the switch to "on"
if you wish to have the carriage return ignored, allowing for print-
ing only when the buffer is full.
The Use of BASIC
Atari BASIC is somewhat different from the Microsoft BASIC used
in this manual. If you do not have the Microsoft BASIC cartridge
for your Atari, the following discussion will help you understand
the modification necessary for the programs given in this manual.
Then you may simply type in the amended programs listed at the
back of this appendix.
Send a program listing to the Gemini using a LIST "P" com-
mand instead of LLiST (as shown in the sample programs in this
manual).
All character-string variables must be dimensional if you are
using Atari BASIC. The maximum length of a string is 99
characters.
If you use Atari BASIC, ending the LPRINT command with a
semicolon causes Atari to insert spaces in the line until it reaches
165
