The Resolution ][ library, and all applications built against Resolution ][, require an Apple ][ machine or emulator that supports the double-high-resolution graphics mode. The following systems are supported:
Enchanced Apple //e with 128k or more RAM and an enhanced 80-column card. If you look at the sticker next to the Open-Apple key (on the power light), the word "Enhanced" should be inscribed on it. If your Apple //e is not enhanced, or if it has less than 128k of RAM, Resolution ][ WILL NOT WORK. Resolution ][ should work fine on the Platinum Apple //e.
All models of Apple //c, //c+, and IIGS.
All modern Apple ][ emulators that support the double-high-resolution graphics mode. For more information, consult the emulator documentation.
Building the Resolution ][ source code requires an MS-DOS, Windows, Macintosh, or UNIX system capable of running the xa65 cross-assembler package (available at http://stockholm.ptloma.edu/cbm/xa/). Currently, Resolution ][ can NOT be built on an Apple ][ machine unless the syntax for all directives in the source code is changed to match the format recognized by Apple ][ assemblers.
I develop and test Resolution ][ on a Linux system running the KEGS Apple IIGS emulator. Special thanks goes to Kent Dickey for creating this wonderful emulator. For more information, visit the KEGS emulator Web page (http://www.psn.net/~kentd/kegs/).
I also test Resolution ][ using a real ROM 01 Apple IIGS. Other than some slight color variation observed with certain pixels, everything works identically to using Resolution ][ in an emulator.
