Development Tools, Apple I

CC65 patches for Apple1/Replica1

The Apple1 is a questionable target for a C compiler due to its small memory size and disjointed memory map. The Replica1, on the other hand, is a near perfect single board target with its 32K contiguous RAM and nice I/O expansion. Compare this with what WDC offers as a single board development platform for $695.

Floating Point BASIC for the Replica I

This Enhanced BASIC is adapted from Lee E. Davidson's version for thr 6502 chip.

A 6502 Disassembler from Apple

The 6502 Disassembler written by Steve Wozniak and Allen Baum for the Dr. Dobbs Journal.

Floating Point Routines for the 6502 by Roy Rankin and Steve Wozniak

Originally published in the August 1976 issue of Dr. Dobb's Journal, these
floating point routines allow 6502 users to perform most of the more popular and
desired floating point and transcendental functions, namely: Natural Log, Common
Log, Addition, Subtraction, Multiplication, Division, and conversions between
floating and fixed point numbers.

Fig-FORTH

This is a figFORTH 1.1 port originally distributed by W. F. Ragsdale for the Rockwell AIM65 back in the late seventies. Will has taken this listing and made a port to the Apple I/Replica I, resulting in a powerful programming environment for experimentation or computer control applications. FORTH is still popular today and is found in such diverse applications as embedded controllers and PDA's to NASA applications on the Space Shuttle! Written in machine code.
