How to install an app on your Commodore 64 - Anil Dash

https://www.anildash.com/2026/10/08/install-an-app-commodore-64/
You will need to ask your mom if you can ride your bike to the mall. The dirt mall is closer, but the magazine stand at the dirt mall doesn’t carry any computer magazines, so you’ll need to take a longer ride to the good mall, where the book store actually has computer magazines. It’s a couple of miles to the mall, so usually you would have a friend come with you, but you called their house and nobody picked up, so today it’s a solo trip.

USBSID-Pico: Bridging Real Commodore 64 Sound to Modern USB - SmallRun

https://smallrun.net/blog/loud/usbsid-pico-sids-on-usb
I am LouD (short for loudness) and I created USBSID-Pico to bridge real SID silicon directly to modern workstations, phones, and media players over USB (CDC/WebUSB/WebSerial), MIDI, ASID and in the future possibly WiFi and Bluetooth. Powered by the Raspberry Pi Pico microcontroller series (rp2040 and rp2350), the board acts as a flexible controller for up to two (and soon four) physical SID chips or modern hardware replacements.

Can a Commodore 1541 disk drive be used as a general purpose computer? - YouTube

https://www.youtube.com/watch?v=6loDwvG4CP8&t=327s
I modified the KIM-1 kernal to run on a bone stock Commodore 1541 disk drive. That's right -- zero hardware modifications. I'll walk you through the theory behind this, and everything I needed to do to make it work, then I'll show you a Hello World example in both BASIC and machine language running on a Commodore 1541 disk drive.

LouDnl/USBSID-Pico: USBSID-Pico is a RPi Pico (RP2040/W RP2350/W) based board for interfacing one or two MOS SID chips and/or hardware SID emulators over (WEB)USB with your computer, phone, ASID supporting player or USB midi controller

USBSID-Pico is a RaspberryPi Pico/PicoW (RP2040) & Pico2/Pico2W (RP2350) based board for interfacing one or two MOS SID chips and/or hardware SID emulators over (WEB)USB with your computer, phone, ASID supporting player or USB midi controller.

Meshtastic 64 Radio Demo on Commodore 64 - The Oasis BBS

https://theoasisbbs.com/meshtastic-64-radio-demo-on-commodore-64/?feed_id=5678&_unique_id=68dfcf2d76f81
The Meshtastic 64 Radio connects through the user port and sits inside a cartridge shell with a built-in battery. Once installed, the device powers up and runs with a custom BASIC program loaded from floppy disk. This software lets the Commodore 64 send and receive text messages across the Meshtastic network, linking retro hardware with modern mesh communication.

BRA and KET: String Interpolation in AmigaDOS | datagubbe.se

https://www.datagubbe.se/braket/
By default, the parser does string interpolation using the characters < (less than) and > (greater than). The cleverness of this is debatable: these characters are also used for I/O redirection, which can quickly make things confusing. Luckily, the parser also accepts the directives .BRA and .KET, each followed by a single character, which lets the programmer override the default interpolation characters. The terms BRA and KET are most likely borrowed from Dirac notation.

The first perfect computer - Celso Martinho

https://celso.io/posts/2025/01/26/the-first-perfect-computer/
That was solved recently when I bought an Amiga 1000 on eBay. This is the long-overdue story about how I restored, fixed, and upgraded it and my future plans. If you’re the rabbit hole type, I added as many links and references as I could so you can dive deeper into the Amiga world. I hope you enjoy reading it.

frntc/SIDKick: SIDKick -- the first complete SID 6581/8580-drop-in-replacement that you can build yourself

https://github.com/frntc/SIDKick
SIDKick is a versatile sound device for C64s and C128s: it serves as a drop-in replacement for the SID 6581/8580 sound chips, and at the same time provides Sound Expander-emulation (Yamaha OPL-based FM sound), a MIDI interface and can control LED stripes. It is based on a Teensy 4.1 and makes no compromises with regard to quality: the emulation is based on reSID and fmOPL. It also comes with a few extras.

too much Fun: The five lives of the commodore 64 computer - About the book

https://www.jesperjuul.net/c64/about.html
With interviews of Commodore engineers and with its insightful look at C64 games, music, and software, from Summer Games to International Karate to Simons' BASIC, Too Much Fun will appeal to those who used a Commodore 64, those interested in the history of computing and video games and computational literacy, or just those who wish their technological devices would last longer.

cbm-hackers mailing list: Professional-1541-DOS (was: Re: Big-PET)

http://www.softwolves.com/arkiv/cbm-hackers/0/0727.html
"The "Professional-1541-DOS" from Mikrotronic System is an add-on for the 1541 and a C64 or a C128 in C64 mode, which is supposed to speedup all read- and write-operations of the drive. The Professional-DOS is an expansion for an already installed speeder with a parallel cable, like SpeedDOS, SpeedDOS Plus, Floppy Flash User System and Floppy Flash Toolkit System."

Lallafa’s Blog » OpenCBM on Mac

http://lallafa.de/blog/opencbm-on-mac
"OpenCBM is a library and a set of command line tools that allow to control old Commodore IEC devices like the famous 1541 floppy disk drive. You can transfer disk image to and from old discs. As modern computers do not provide a IEC connector, OpenCBM allows to control adapters that attach to your PC. Older PCs use parallel port cables (like the XA1541 or XS1541) and newer ones use a USB adapter (XU1541 or XUM1541). This pages shows you how to use OpenCBM on your Mac. As modern Macs only support USB connectors and no parallel ones, we focus on setting up the XU1541 or XUM1541 devices."

David Simons, the author of Simons' Basic - Commodore 64 (C64) Forum

http://www.lemon64.com/forum/viewtopic.php?p=394597&sid=5186e8a3fc0f2c10e1271ffdb34afddb#394597
"After Simon's basic I went to university and studied computing and economics. From there I joined SCO (Santa Cruz Operation) and worked on their Unix kernel which was something I always wanted to do. I then joined a startup which unfortunately didn't make it but had a lot of fun (implementing an open source J2EE app server). I've since worked for a number of other companies including Sun and I now work for the leading virtualization company."

Dave Farquhar's Silicon Underground - How to connect a Commodore 64 to a television

http://dfarq.homeip.net/article/20050104084808610
"What if you can't find a Commodore video cable? If you're handy with a soldering iron, you can make your own cable with parts from Radio Shack. You'll need a 5-pin DIN plug, two male RCA plugs, and two lengths of speaker wire. Shielded cable like RGU-58 would be better, but isn't totally necessary. "

C64 Standard Tape Interface

http://www.zimmers.net/anonftp/pub/cbm/documents/projects/interfaces/soundcard2tape.html
"This is an interface which lets you connect your C64 to ANY standard Tape Player instead of the custom made C1531 device, which can be hard to get today. Also it means you can connect your C64 to any PC with a sound card and let the PC act as a Tape Player with a perfectly clear sound - so there are no Load errors possible."

GoatTracker - C64 SID music editor for Mac OS X

http://www.sidmusic.org/goattracker/mac
"GoatTracker is a cross-platform tracker written by Lasse Öörni, producing SID chiptune music for the Commodore 64, and released with source code under the GPL. It is notable for being possibly the only SID chiptune-composer NOT native to the C64, as many alternative composers (including JCH, and CyberTracker) only execute on the C64 or inside C64 emulators. Many SID tunes are available in various formats on the Internet, especially through the High Voltage SID Collection (HVSC). GoatTracker is capable of directly exporting to the .sid (PSID/RSID) file format in addition to standard C64 PRG files."

The diskette that blew Trixter’s mind « Oldskooler Ramblings

http://trixter.wordpress.com/2008/09/28/the-diskette-that-blew-trixters-mind
"The manual for Mental Blocks claims that, for both C64 and IBM, you put the diskette in label-side up. I thought that had to be a typo, since every single mixed C64/IBM or Apple/IBM diskette I have ever seen is a “flippy” disk where one side is IBM and the other side is C64 or Apple — until I looked at the FAT12 for the disk and saw that tons of sectors in an interleaved pattern were marked as BAD — very strange usage."
