Mapping The C64. Technologically Induced Coma: Understanding 6502 assembly on the Commodore 64 - (6) Our instructions to assembly. In chapter 3 we listed all of the instructions we had done with regard to memory modification to achieve or goal.
Today we will convert those instructions into assembly and then onward to machine code where the C64 can understand it and execute the tasks. In order to accomplish this, we will have to introduce a couple of new things that our program will require. I will spend extra time on those things not previously discussed. Ive tried to keep the complexity to a minimum. You will find with assembly that like anything else, the more you optimize something, the more difficult it is to understand. Lets get started!!!!!!
From our memory map we read $C000-$CFFF 4K Free RAM Locations 49152 to 53247 ($C000 to $CFFF) are free RAM. In other words, lots of free space to store an assembly program. 6502 Assembly. Easy 6502 by skilldrick. Introduction In this tiny ebook I’m going to show you how to get started writing 6502 assembly language.
The 6502 processor was massive in the seventies and eighties, powering famous computers like the BBC Micro, Atari 2600, Commodore 64, Apple II, and the Nintendo Entertainment System. Bender in Futurama has a 6502 processor for a brain. Even the Terminator was programmed in 6502. So, why would you want to learn 6502? Arnold.c64.org.

CodeBrane Blog. I’ve been rebooting my interest in the Commodore 64 recently, after a layoff of around 20 years!
The last time I used a 64 was back in 1992 when I wrote a BASIC word processor on which I typed my honours thesis and printed out on an MPS printer, if I remember the model correctly. I still have the old machine, printer, tape drive etc but I’ve been relearning everything on VICE before I get round to powering them up again. So this is a wee tutorial on how to display a simple Hello World message in C64 assembler. It won’t be ‘type and run’ sort of thing as I’ll show how to add a BASIC header so you can compile the object code and run it as a normal program from BASIC. So, let’s crack on. First go and get the VICE emulator. The Commodore 64 Scene Database. MEGA65 8-bit computer.
ZoomFloppy - RETRO Innovations. ZoomFloppy PCB (Assembled) Introduction ZoomFloppy brings Commodore disk archival into the 21st Century, bridging the gap between the both the IEEE-488 and IEC-based disk intelligent Commodore™ disk drive line and contemporary personal computers.
Taking up the baton from the ever-popular X*-1541 line of parallel port interfaces, ZoomFloppy provides complete functionality for newer machines running multitasking and multi-user operating systems and those systems lacking the legacy parallel port upon which the X*-1541 interfaces depend. Designed by Commodore enthusiast Nate Lawson, ZoomFloppy utilizes the ubiquitous OpenCBM Commodore device access libraries and application utilities for operation. In addition, applications like the VICE Emulator that include OpenCBM support will work with ZoomFloppy as well.
ZoomFloppy offers unparallelled performance and robustness for the serious Commodore enthusiast. Commodore C64, C128 High Quality S-VIDEO & Composite Video Lead TV Video Cable. C64 Reloaded – breadbox64.com. April 1st 2014, Jens Schönfeld of Individual Computers announced the future release of newly produced Commodore 64 mainboards also known as the ‘C64 Reloaded’.
The new PCB’s are based on the Commodore 64 Assy no. 250466 in celebration of the Commodore 64’s 32nd birthday that year, or when written in hexadecimal notation ‘$20’. Before the mainboards were actually released for sale on his website, an e-mail auction was made for the real hardcore fans of the machine. The 20 highest bidders would get a numbered copy of the board with a choice of ZIF sockets or turned precision sockets for the four larger chips: SID, VIC-II, CPU and PLA.
The Commodore parallel cable. For Commodore 1541, 1570 and 1571 drives Description The Commodore parallel cable is a companion cable for the Commodore serial cable and gives you an additional parallel connection between a Commodore 1541, 1570 or 1571 drive and a Commodore machine.
To be precise, there are two quasi-standard parallel cables for Commodore machines. The original Speed DOS parallel cable was designed for Commodore 1541 drives only. It has become a standard since then because this kind of parallel connection is supported by many other DOS accelerators and stand alone copy software. SD2IEC Info. Of all the methods of loading stuff into your Commodore, the SD2IEC family of SD readers are the business.
SD2IEC emulates the basic functions of an 1541, as well as supporting fast loaders like JiffyDos and Final Cartridge III and Epyx Fast Loader. These tips are my recommendations and not the ONLY way of using an SD2IEC. If you are already a Commodore disk drive user, you’ll get the hang of it in seconds! If you’ve never used a real disk drive, follow the information here, and you’ll soon be using your Commodore like a grown up! Below you'll find a brief explanation of how to prepare an SD card, installing FileBrowser and directory structure. Formatting an SD card: Cables and adaptors. The following cables and adaptors are discussed on these pages.
For a detailed guide on selecting among X1541-series cables, read the cable selection guide on the X1541-series interfaces page. The descriptions and construction guides on these pages are for beginners. If you are a hardware expert then, please, bare with them. All_About_Your_64-Online-Help Version 0.64.

Cc65 - a freeware C compiler for 6502 based systems.

Turbo Assembler is a native c64 assembler which was introduced in 1985 by the German company, Omikron. Aside from Omikron, the software credits only one author: Wolfram Roemhild. Over the years, Turbo Assembler has become the most modified piece of c64 software ever. There are other programs that vie for the title, for sure - how many versions of CCGMS are in your diskbox? Dir Master and all of its many variants, oh yes, Cruel and Time too... but none of these have the sheer number of modified versions as Turbo Assembler.
This site's mission is twofold: Serve as the online home for the Turbo Macro Pro line of software, a collection of advanced modifications developed and maintained by Style, as well as TMPx, a Turbo Macro Pro compatible cross assembler. In our quest to collect as many modified versions of Turbo as possible, we invite any interested and willing people to help. Send us any missing modifications that we haven't documented as in the archive. 2.2. An Example Interrupt. Kick Assembler. This is the homepage of Kick Assembler.

With over 20 years in the computer service industry, and many of those included repairing C64s and drives along with building custom cables for customers or personal use, I feel very qualified to offer my skill to the C= community.
I offer the most common X cables that Joe Forster/STA lists on his site, not the X adapters as I have no ability to make the PC boards required. Special cables not listed below will be considered on a case by case basis and if I have the parts to build them. Not all the information that is present on Joe's site is here. There's much to learn about and glean from Joe's web pages, so I do recommend reading them to the fullest. The prices for the cables are in Canadian dollars and do not include shipping. If you need help choosing a cable, look at my pick a cable matrix page to help.
