Just to reiterate what's already been said by Vincent Foster, to use
double Hi-Res you need:
o Apple //e with revision 'B' motherboard.
o Apple Extended 80 column card with a jumper (supplied with card)
installed between the molex connectors.
If you can find them, the following issues of Softalk had articles on
double Hi-Res:
"Hi-Res Double Play"
by Don Worth
July, 1983
-A good overview of how the double hi-res display works and how
it differs from standard hi-res. Includes example Applesoft
programs to put the concepts to use.
"Applesoft Brushes for Double Hires"
by Peter Baum and Larry Roddenberry
September, 1983
-A more in-depth discussion of making use of DHR. Included is an
assembly language listing to implement DHR versions of HPLOT
graphics commands from Applesoft using the ampersand vector. (A
friend of mine is customizing these routines for use in a NAPLPS
implementation for the //.)
Beagle Brothers puts out a disk that does similar things with DHR, the
name of it escapes me at the moment. Nice thing is that BB never copy
protect or lock up their disks, so you can look at every file to see
how it ticks.

The Beagle Brothers package that uses Double Hi-Res Graphics is called 'Beagle Graphics' and I highly recommend it. It adds about 30 '&' commands for both Double Hi-Res and Lo-Res, including draw and fill commands, and load and save commands. The package also includes a drawing program (I personally like another better), and utilities for converting normal Hi-(Lo-)Res pictures to a Double format. It also includes a slide show program, and DHGR compress program. For printing out your DHGR and DGR pictures, you need Beagle Brothers 'Triple Dump' package. This supports many printers and interfaces, and allows cropping and zoom effects, and the printing of text screens and regular graphics as well. It also supports some color printers. The BEST Drawing Program (in my opinion) for DHGR is 'Dazzle Draw'. It turns your Apple //e into a Color Macintosh! It really is fabulous, even though it is slightly copy-protected, and uses Prodos (which I'm still uncomfortable using). But you can use either the keyboard, paddles, joystick, mouse(my favorite), or graphics tablet. You get a dazzling array of colors, brushes, patterns, spray paint, flood fill, free-hand, lettering, and an assortment of other little tricks. And the handiest command - UNDO! A program well worth the money, it will make an artist out of anyone who wants to take the time - this tool is all you need!
