This is a general purpose library in 6502 Assembly for the Apple II. I am learning both Git and Assembly for the first time as I create, update and maintain this, so expect some mishaps: wasted CPU cycles, weird documentation, accidental catastrophes, and so on. I am using Merlin 8 Pro (DOS 3.3) for this project, but this should be fairly easy to convert to other assemblers as well as other 6502-based systems.
|
||||
|
||||
Ultimately, my aim is to create a large enough collection of routines to address any domain of development for the Apple II family in Assembly. I will be heavily relying on texts like Roger Wagner and Chris Torrence's _Assembly Lines_ and Lance Leventhal's _6502 Assembly Language Routines_, as well as a plethora of online sources. I'll do my best to acknowledge when a routine is inspired by (or mostly copied from) another source, and will exclude them from the Apache License 2.0 when necessary. If you find your own source here, but would rather it not be here, please reach out to me and I'll remove it immediately.

## Disk Overviews

Each disk contains a single Macro (.mac) file, one or more subroutine libraries related to the overarching theme of the disk, and a "minified" version of the required.mac and required.lib files that the entire library relies upon. Additionally, each library has a correlating .hooks file for declaring variables used in that library's operations, as well as individual copies of each subroutine for compiling custom libraries for any given project and a demo program. Currently, there are also "minified" versions of each library and subroutine that have no comments as well, but these may be transferred to their own disk(s) in the future if disk space becomes a major concern.

In the following descriptions, we'll be listing the .mac contents that are relevant to the theme of the disk only, as many of the macros are calls to single subroutines and it would be redundant to list those as well. A table in section XXX lists the calls each macro makes to each subroutine, and the required.mac macros are listed in Disk 2 only.

This disk is dedicated to Standard Input/Output operations, and a couple non-standard ones. Note that this is for 40-column mode only in order to keep compatibility with earlier hardware, and focuses on screen output alone in order to help with execution speed. Additionally, this focuses on input from the most-used peripherals: the keyboard and game paddles. Libraries for 80-column mode, as well as input and output from and to other devices, will be added later on.

This disk is dedicated to Standard Input/Output operations, and a couple non-standard ones. Note that this is for 40-column mode only in order to keep compatibility with earlier hardware, and focuses on screen output alone in order to help with execution speed. However, most of these subroutines will work in 80col mode, with the exception of those that use DMA.
