INTRODUCTION TM The Grappler Interface is a Centronics compatible parallel interface for the Apple II/II+ Computer. In addition to advanced text features, it offers high resolution dot graphics (HIRES) dump routines located in firmware. These are easily invoked using simple control commands.
5. Be sure the power is off. Insert the Grappler card into slot #1 (or any other slot except zero) with a gentle rocking motion until fully seated. 6. Pass the cable through one of the vertical openings in the back of the Apple case. 7. Replace the Apple’s cover.
To type a control character, hold down the control key (marked “CTRL’ on the Apple) and then press the appropriate letter. Then release the letter key, and then the control key.
CTRL-I X Don’t output the high order bit to the printer. This puts the printer back in standard text mode. CTRL-InN Set line length to n characters from left side of page (not from left margin). After issuing this command, characters will only be printed on the printer, and not on the Apple video screen.
lines per page (this may vary with the type of printer). Therefore if you specify a printed page length of 6Ø lines (CTRL—I 6ØP), your printer will print 6Ø lines and automatically skip over the perforation with 6 line feeds. CTRL—I B Turn on bell.
GRAPHICS FEATURES AND COMMANDS The Grappler Interface can output the HIRES screen to the printer by using simple commands. All graphics commands consist of the command character (usually CTRL—I) followed by a “G", and any options described below.
R — Rotate the picture 90 degrees in a clockwise direction. Some printers require this option when printing the image double- size. (See D above.) An example of a graphics command would be CTRL-I GDIR2 followed with a carriage return. This will print the inverse of HIRES page 2, double size, rotated 90 degrees.
PASCAL AND CP/M COMPATIBILITY The Grappler is compatible with both PASCAL and CP/M. PASCAL l.Ø and CP/M will both recognize the card as a serial interface. Entry points have been provided to mimic a serial interface so that the card will function properly with these systems.
FOR ADVANCED PROGRAMMERS: MEMORY LOCATIONS USED BY THE GRAPPLER The Grappler Interface uses those RAM locations set aside for its particular slot and the slot scratchpad area common to all slots. The ROM is turned on using the standard ROM expansion protocol and resides in locations $C8ØØ to $CFFF.
CUSTOM DRIVERS If you are writing your own drivers the following locations are used to access the card CY = NO where N = slot#) Printer Status — $CØSl,Y (READ) Output Latch - $CØ8l,Y (WRITE) Strob.
APPENDIX A TM USING GRAPPLER CONMANDS WITHIN A PROGRAM The following table illustrates how a few Grappler commands would be used within a program: INTEGER BASIC DESCRIPTION TM 1Ø PRINT “CTRL-D”;.
The following prograas allow you to rest the graphics capability of the Grappler. For Applesoft basic users: 5 TEXT 1Ø HOME 2Ø PRINT ‘ENTER THE SLOT YOUR GRAPPLER IS IN AND” 3Ø INPUT “HIT THE.
For Pascal Users: PROGRAM DEMO, USES TURTLEGRAPHICS, APPLESTUFF, VAR ANGLE, DISTANCE: INTEGER; PRINT, TEXT, BEGIN ANGLE;8-Ø; INITTURTLE; PNNCOLOR(NHITE); FOR DISTANCE:= TO 99 DO BEGIN MOVE (2*DISTAMCE); TURN ANGLE); END, REWRITE (PRINT,’PRINTER;"), NRITELN (PRINT,CHR(25),G');(*USE CHR(25) [CTPL—Y]IN PASCAL*); END.
The following program will allow you to print a graph that has been previously saved to the disk. For e,~as~ple, after saving the qreph created by one of the popular graphing programs for the Apple, run this program to print it on your printer. Note: If your Grappler is not in slot #1 change line 5 so that S equals the clot number of your Grappler.
APPENDIX B DIP SWITCH SETTINGS FOR YOUR PRINTER All printers must configure to a Centronics type psrallel interface. ANADEX 95ØØ — 93Ø1 All switches on S—3 must be off. Set switches on S-1 snd S—2 appropriately. CENTRONICS 739—1 All four switches oust be off.
