Only console I/O is supported (no disk subsystem for these, yet). To build for Apple1, use " -t apple1 " on the command line, use " -t replica1 " for Replica1. The difference between the two is the RAM memory map. To build the compiler, download and untar the cc65 compiler source archive for version 2.11.0. Untar this patch, which creates a similar directory structure with only the patched/new files. Copy the patched files into the original source tree. Build according to the documentation. I've only tested the build under OSX, but should work fine on all the supported host environments. I've done basic testing of the generated targets on the Replica1 SE and Pom1 emulator. In order to download the binary to the computer, you will need to use whatever mechanism you have. I use Vince Briel's serial port interface, so I created a utility program, located in util/apple1/bintomon.c that reads the binary and outputs a text file that can be sent through your terminal program to the target. All binaries are built to load at $280, right after the keyboard input buffer. To load a binary into the Pom1 emulator, load a raw memory file into address $27C. The binary has a 4 byte header so this load address is needed to put the code and data at the correct address. 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.

Used with the author's permission. Not to be sold. This is an assembly dump of the program I played with on an Apple I some 27 years ago. I am still amazed that it plays chess as well as it does. Sat, 19 Mar 2005 08:05:43 -0800 http://www.applefritter.com/node/6970 This Enhanced BASIC is adapted from Lee E. Davidson's version for the 6502 chip. It is a floating point BASIC that, on the Replica I, resides at addresses from $5800 to $7FFF, and uses memory from $0280 to $02FF for various storage. The space from $0300 to $57FF is your program storage area. It is free for your use, but is not to be resold. Refer to Mr. Davidson's web-site for details and language references at: [url]http://members.lycos.co.uk/leeedavison/index.html[/url] And while you're at it, send Lee Davidson a thank you for his fine job!

Sat, 12 Mar 2005 13:41:25 -0800 http://www.applefritter.com/node/6876 Floating Point Routines for the 6502 by Roy Rankin and Steve Wozniak These are different than the handwritten notes from 1976. 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. In the November/December issue of Dr. Dobb's Journal Roy Rankin published three error corrections to the Floating Point Routines presented above. Floating Point Implementation in the Apple II by Steve Wozniak An almost identical set of the above routines appeared in the original manual for the Apple II (the Red Book, January 1978). Documentation for these routines appeared in another book, the Wozpak II, in November 1979.

Sat, 12 Mar 2005 12:38:17 -0800 http://www.applefritter.com/node/6867 Dated 4-6-76, this is a 10 page hand written PDF from Steve Wozniak. Handwritten source code at the end. The scans are 600dpi B/W preserved due to the efforts of David Craig. This file is for All 6502 machines, but was authored in the Apple I erra. I can provide this, plus many other historical apple documents on 5 DVDs for the cost of duplication. e-mail grant@stockly.com Sat, 12 Mar 2005 06:47:01 -0800
