Joe's HP 9872 Quick Reference Card

Created 1/7/98
Here are the images of the front and back of the HP 9872 Quick Reference card (PN 09872-90004). The original card is double sided and measures about 5 x 8 inches. The card lists all the commands for the 9872Plotter ROM and the HP 9872A Plotter and has a brief description of the meaning of each.

The 9872 Plotter ROM is a plug in ROM cartridge designed to be used in the HP 9825 , 9835 , 9845 and 9831 calculators. It adds commands for the HP 9862 and HP 9872 plotters to the calculators vocabulary.

The HP 9867 Plotter* replaced the HP 9862 Plotter and was a four pen plotter capable of plotting in four colors. In addition, it was capable of digitizing images. Both of these use the HP-GL and used a modified HP 98032 inteface adaper for a 16 bit parallel interface.
