You Can Now Order A Brand-New Amiga PCB

October 19, 2023 by 30 Comments

The Commodore 64 has been pulled apart, reverse engineered, replicated, and improved upon to no end over the last four decades or so. The Amiga 500 has had less attention, in part due to its greater level of sophistication. However, you can now order a brand-new Amiga-compatible PCB if you’re looking to put together a machine from surplus parts.

The design is known as Denise, and is apparently the work of an anonymous Swedish designer according to the Tindie listing. It’s not a direct replica of any one Amiga machine. Instead, it’s best described as “a compact A500+ compatible motherboard with two Zorro2 slots and a few additional features.”

Denise is just a PCB, though. No emulated chips or other components are included. To use the PCB, you’ll need a full set of Amiga custom chips and a suitable Motorola 68000-series CPU to suit. It can be used with either OCS or ECS chipsets. At this stage, it’s only verified to work with the 2MB version of the Agnus chip, though the creators believe it should work with a 1MB “Diet Agnus.”  Some modern conveniences are on hand, too. A pair of microcontrollers will allow the use of Amiga or PC keyboards, along with Amiga or PS/2 style mice, including support for scroll wheels.

Given the number of damaged, battered, and corroded Amiga PCBs out there, it’s great that there is a source of fresh, new PCBs for restoration purposes. Video after the break.

An Amiga 500 with a blue case and blue accessories

Restored Amiga 500 Is Blue – And Glows In The Dark

July 21, 2023 by 5 Comments

Few things are as satisfying to watch as a good retrocomputer restoration project – we’re always happy to see someone bring a rusty old Commodore, Apple or Atari back to life. The goal is typically to get the machine as close to its original state as possible, except for perhaps a few non-intrusive mods like memory upgrades. [Drygol] however, had already done this so many times that he thought it was time to take a different route for once, and apply some creativity to an old Amiga 500 case. Originalists may shudder, but we quite like his funky blue-and-yellow A500 mod.

Missing keys, random stickers and an ugly paint job: the A500 wasn’t looking great at the beginning

To be fair, [Drygol] wasn’t the first one to modify this specific Amiga’s case: one of its previous owners had already applied a rather shoddy blue paint job and defaced it with some stickers. [Drygol] decided to stick with the basic idea, but do it right this time. First he removed the old paint using concentrated lye, then gave it a fresh coat of blue. He also applied glow-in-the-dark paint to the Amiga logo embossed in the case and added a fluorescent yellow laser-cut circuit board ornament. It took a bit of experimenting to get all these elements just right, but the end result definitely looks the part.

The insides of the Amiga also needed some TLC: [Drygol] competely cleaned and lubricated the floppy drive, gave the motherboard a good ultrasonic scrub, and replaced dodgy capacitors all over. He expanded the RAM from 512 kB to 1 MB and added a Gotek floppy emulator, which can work in parallel with the original disk drive. To make the Gotek easy to operate, [Drygol] placed its OLED screen and a pair of touch-sensitive buttons in a cutout on the front of the case.

A matching blue mouse and gamepad, both connected through the MouSTer adapter, complete the setup. The result is a good-looking A500 with some modern conveniences that’s perfect for exploring the Amiga’s extensive software library. If custom colors aren’t your thing, you’ll be happy to know that the original shade of grey or beige might be available for your retro console, too.

Hackaday Prize 2022: A Functional Commodore PET Tribute

July 28, 2022 by 13 Comments

The C64 may be the best-selling computer of all time, but Commodore made several machines before that, too. [Mjnurney] always loved the Commodore PET, and set about building some new machines in the PET’s unique all-in-one form factor.

The case design started with measurements taken from an original Commodore PET, of which [Mjnurney] has three. Then, it was modified and extended to make room for a proper keyboard. The case also mounts a 14″ IPS display, two 15W speakers, and a gas strut enabling the case to be propped open for easy maintenance. It’s actually made out of real sheet metal, too!

The primary version mounts an Amiga 500 inside, including its classic keyboard. However, [Mjnurney] has developed a PC version, too. Both look great, and it’s wild to see Netflix displayed on a machine that looks more at home in 1977. Perhaps most of all, though, we love the dual floppy drives just below the screen.

Throwback cases pay tribute to some of our favorite machines. The tiny ones are perhaps the cutest of all.

Why You (Probably) Won’t Be Building A Replica Amiga Anytime Soon

June 16, 2020 by 68 Comments

Early in 2019, it  became apparent that the retro-industrial complex had reached new highs of innovation and productivity. It was now possible to create entirely new Commdore 64s from scratch, thanks to the combined efforts of a series of disparate projects. It seems as if the best selling computer of all time may indeed live forever.

Naturally, this raises questions as to the C64’s proud successor, the Amiga. Due to a variety of reasons, it’s less likely we’ll see scratch-build Amiga 500s popping out of the woodwork anytime soon. Let’s look at what it would take, and maybe, just maybe, in a few years you’ll be firing up Lotus II (or, ideally, Jaguar XJ220: The Game) on your brand new rig running Workbench 1.3.

Doom Clone Shows What An Alternate-Reality Amiga Could’ve Had

May 4, 2020 by 31 Comments

Can you run Doom on the Amiga? No, not really, and arguably that was one of the causes for the computer’s demise in the mid-90s as it failed to catch up on the FPS craze of the PC world. [Krzysztof Kluczek] of the Altair demogroup has managed not exactly to remedy that status with the original article, but to show us how a potential contender could’ve been designed for the unexpanded Amiga hardware back in the day.

Many developers tried to emulate the thrill and ambiance of the id Software shooter, but they all required high-end Amigas with faster processors and expanded memory, limiting their player base on an already diminished demographic. Not only that, but even with fancier hardware, none of them quite managed to match how well Doom ran on your run-of-the-mill 486 at the time. [Krzysztof] isn’t trying to port Doom itself, but instead creating an engine custom-designed to take advantage of, and minding the limitations of the OCS Amiga as it existed in 1987. The result is Dread, a 2.5D engine that resembles the SNES port of Doom and uses assets from the Freedoom project in order to remain copyright-abiding.

It might not be Doom, but it’s a good peek at what the 33-year old hardware could’ve done in the right hands back then. Technically it already surpasses what the Wolfenstein 3D engine could do, so there’s an idea if someone ever aims to make a straight up port instead of their own game. If you like seeing Doom run on machines it wasn’t meant to, boy do we have some posts for you. Otherwise, stick around after the break for two videos of Dread’s engine being demonstrated.

Expansion Board Puts Spotify On The Amiga 500

March 20, 2020 by 16 Comments

No doubt some purists in the audience will call this one cheating, since this Amiga 500 from 1987 isn’t technically connecting to Spotify and playing the music by itself. But we also suspect those folks might be missing the point of a site called Hackaday. With all the hoops [Daniel Arvidsson] hopped through to make this happen, what else could it be if not a hack?

This one starts, like so many projects these days, with the Raspberry Pi. Don’t worry Amiga aficionados, this classic machine hasn’t been gutted and had its internals replaced with a diminutive Linux board. But thanks to an expansion card known as the A314, you could say it’s received a penguin infusion. This clever board allows an internally mounted Raspberry Pi to communicate with the Amiga 500 through shared memory, making all sorts of trickery possible.

In this case, the Raspberry Pi is actually the one connecting to the Spotify Connect service with raspotify and decoding the stream. But thanks to a few pipes and an ALSA plugin, the audio itself is actually pushed into the Amiga’s sound hardware. In the video after the break, the process is demonstrated with tunes that are befitting a computer of this vintage.

This process is similar to how one classic Apple fan got Spotify running on their Macintosh SE/30 with a similar respect for the vintage hardware. Of course if you actually want to gut your Amiga 500 and replace it with a Raspberry Pi, we’ve seen some pretty good conversions to get you started.

Writing Dance Bangers Like It’s 1990 Again

February 4, 2020 by 14 Comments

Dance and house music exploded in a big way at the end of the 1980s. Typically the product of well-equipped studios with samplers and mixers worth thousands of dollars, it was difficult for the home gamer to get involved. That was, until the advent of the glorious Amiga, as [cTrix] ably demonstrates.

Sampling on your Amiga often meant sneaking off with the family hi-fi.

The video explains the history of both the music and the hardware, and highlights just why the Amiga was so special. Packing stereo audio and a four-channel sound chip, it had the grunt to pump out the tunes. All it was lacking was an audio input – which is where third-party hardware stepped in. Parallel-port analog-to-digital converters hit the market in a big way, letting users sample audio on their home computer without breaking the bank.

[cTrix] then proceeds to demonstrate how one would go about producing a dance track on an Amiga way back in 1990. A home stereo is used to play records, hooked up to a Stereo Master parallel port sampler. With a bunch of drum, piano, and synth samples recorded and saved on disk, a tracker is then used to assemble the track. It’s then compared with other music from the era as a great example of how things used to be done.

Overall, the Amiga will long have a legacy as the machine that brought real multimedia capabilities to the home computer. It’s one of our favourites, though keeping them going can be tough sometimes. Video after the break.
