Some Assembly Required
Super Mario 64 becomes a living diorama on Apple Vision Pro. Each level sits on your real table, and you walk around it while you play with a game controller. You are the camera: lean in for a closer look, or step around the table to see Mario from any side.
The VIISAN VF3240 is a 2400 dpi A3 flatbed scanner, sold under several names for a few hundred euros. Above 600 dpi, every scan has three defects, coming from the LEDs, from the motor, and from the sensor. vf3240 is an open source driver that talks to the scanner directly over USB and removes them. This article is about the three defects and how they are corrected.
Zum 40jährigen Jubiläum des 64’er Magazins präsentieren wir das Kunstprojekt www.64er-magazin.de: eine Website, die so tut, als wäre 1984. Exakt 40 Jahre nach der ursprünglichen Veröffentlichung erscheint hier jeden Monat eine neue Ausgabe:
CCGMS Future 0.2 was just released. It adds 80 columns support, a true ASCII charset (in 80c mode), and bug fixes.
The CCGMS Terminal Program for the Commodore 64 is maintained again, and there is a new version: CCGMS Future 0.1, with bug fixes and new features.
All disk drives connected to the Serial Bus of a Commodore 64 speak the Commodore DOS protocol, from the popular 1541 5.25″ drive to the modern sd2iec SD card interfaces. CMDR-DOS is a new and open source implementation of the Commodore DOS protocol, using SD cards with the FAT32 filesystem and supporting advances features like partitions, subdirectories and timestamps – and running on a 65c02!
We are presenting the (to our knowledge) first full-featured open source library for 65c02 CPUs for accessing FAT32 formatted disks.
The system software of the Commodore 64 has been extensively reverse-engineered. Next to disassemblies of the ROM, several “memory maps” have been published: tables that document system variables in the first kilobyte of RAM, and how to tweak the system software with PEEK and POKE. Now, I’m presenting the Ultimate C64 Memory Map: A C64 memory reference that shows eight sources side-by-side.
NES and SNES controllers support 8 to 12 buttons with only three data pins (plus VCC/GND). Let’s attach them to a C64 – or any 6502-based system!
There have been a few new interesting additions to the Commodore Source Code repository, including:
The Final Cartridge III is great: It comes with a disk speeder, BASIC extensions, an excellent monitor – and an impressive, but ultimately useless GUI, because there are practically no applications for it. Let’s replace the FC3 GUI with GEOS!
The monitor built into the Final Cartridge III is one of the best ones for the C64. Some of its unique features are:
In the series about the variants of the Commodore Peripheral Bus family, this article covers the lowest two layers (electrical and byte transfer) of the “Standard Serial” bus as found on the VIC-20/C64 as the main bus, but also supported by all other Commodore home computers.
The original Commodore 64 KERNAL and BASIC source code has been available for a while. It used to be built using Commodore’s assembler of a PET.
My side-by-side C64 ROM disassembly/commentary page has been completely redone!
The original Commodore TED (C16, C116, Plus/4) source code has recently appeared on zimmers.net. It is also available in my Commodore Source Code git repository.
You might think the DOS ROM of the Commodore 1541 disk drive has been analyzed to death. But here are two new resources:
In my quest to make the C16 more usable, i.e. more like the environment I’m used to, i.e. a C64 with a Final Cartridge III, I’ve ported the Final Cartridge III monitor to the TED series (C16, C116, Plus/4).
Over the years, the ROM source code of many Commodore computers and peripherals has appeared. I have been collecting them in a git repository here:
