Before we begin, let us soothe those first dreaded thoughts. No, the commodore was not destroyed in the process. They can simply clip the 16 wires they added to interface the keyboard and be back to stock. Breathe a sigh of relief, and enjoy the twypper, a twitter wall made from a commodore SQ1000.

[Alex] needed to make an interesting project for his companies Openspace/hack day.  A friend, suggested a twitter wall, and that’s when [Alex] got the idea for a typewriter. After a quick search, he found oomlaut’s typewriter.  They didn’t let that deter them from making their own version though. They found a nice fully functional commodore SQ1000 and began hacking. Ultimately they simply decided to use an Arduino to short the key switches to simulate typing. There are all kinds of details on the necessary steps to get the typing to function absolutely correct on the project page. Over all it was well done and we’re happy to see that it can be undone just as easily.

Jamin’ To Bach, Commodore 64 Style

[thrashbarg] missed the sounds of the Commodore 64 and longed to hear the great masters in 8-bit glory. To get his fix, he created a midi device using the original Sound Interface Device from those long-dead systems. He’s interfaced the MOS6581 SID with an Atmel AVR ATmega8 microcontroller. The receiving pin for the AVR’s UART is used as a MIDI-IN connection, with the microcontroller converting midi data into the proper sound generation specs for the SID. The result is the 10 minutes of [Bach]’s Brandenburg Concerto heard in the embedded video above.

We have no idea where he picked up this obsolete chip, but if you want to give this a try, perhaps you’ll have some luck emulating the MOS6581 by using another ATmega8.

Commodore 64 Laptop

[Ben Heck] has just completed one of his more unique laptop game consoles. This time around it’s a Commodore 64, which he’s been attempting since 2006. Recently he scrapped everything and started fresh on what turned out to be the fastest build yet. While it certainly looks similar to his other laptops, he put in a lot of effort to give it the appearance of an 80’s computer from the beige color to the texture. He used an original C64C motherboard since it was the final and smallest revision and coupled that with an original keyboard. A 1541-III-DTV allows use of an SD card as a floppy device. Just drag any disk image onto the card and it’s ready to go. Check out a video of it in use below.

BBS On A Commodore 64

August 21, 2008 by 32 Comments


[Lief Bloomquist] was in need of some geeky nostalgia. He thought making a BBS server on a Commodore 64 would fill that need perfectly. He used a PC running some routing software to make the BBS server available over the net, without any long distance charges. Anyone with an Internet connection can telnet to the BBS and join the fun.

[Jason Scott] made BBS: the Documentary. He has interviewed [Lief] and taken some pictures of the set up. You can view them, as well as download a PowerPoint about the project here.

[Jeff] has been playing around with Parallax’s Propeller chip. He’s used it to adapt an NES controller to the to the Commodore 64. In this latest iteration though, he’s added a Memsic 2125 dual axis accelerometer to the end of a whiffle ball bat and used that to provide Wii style controller input. The video above shows his son playing Street Sports Baseball with it.

Hacking The Commodore 64 DTV Version 2

c64

The original C64 DTV was a joystick containing 30 games sold in 2004. It attracted hackers because it could be modified into a fully functioning console. The latest version of the chip is being sold inside a Radio Shack Hummer game. This version fixes bugs in the original and adds several features to improve memory access and CPU speed. Before you get started there are several modifications that need to be done to improve the video and audio quality of the system. Once these mods are complete you can start playing with the machine just like an original C64. Oh, the Hummer game will look a lot better too.

Behold A First-Person 3D Maze, Vintage Atari Style

October 20, 2024 by 15 Comments

[Joe Musashi] was inspired by discussions about 3D engines and decided to create a first-person 3D maze of his own. The really neat part? It could have been done on vintage Atari hardware. Well, mostly.

He does admit he had to do a little cheating to make this work; he relies on code for the ARM processor in the modern Atari VCS do the ray casting work, and the 6507 chip just handles the display kernel. Still, running his demo on a vintage Atari 2600 console could be possible, but would definitely require a Melody or Harmony cartridge, which are special reprogrammable cartridges popular for development and homebrew.

Ray casting is a conceptually simple method of generating a 3D view from given perspective, and here’s a tutorial that will tell you all you need to know about how it works, and how to implement your own.

[Joe]’s demo is just a navigable 3D maze rather than a game, but it’s pretty wild to see what could in theory have run on such an old platform, even if a few modern cheats are needed to pull it off. And if you agree that it’s neat, then hold onto your hats because a full 3D ray casting game — complete with a micro physics engine — was perfectly doable on the Commodore PET, which even had the additional limitation of a monochrome character-based display.
