Page 2: Installation Instructions
INTRODUCTION 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. There is no standardization among printer manufacturers for dot graphics. - Page 3 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. Pass the cable through one of the vertical openings in the back of the Apple case. Replace the Apple’s cover.
- Page 4 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. Control characters do not appear on the screen as they are typed.
- Page 5 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.
- Page 6 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.
- Page 7 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. If no other options are used (i.e.
- Page 8 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.
- Page 9 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.
