A Tale Of More Than One Amiga 1500

July 14, 2018 by Jenny List 32 Comments

If you were an Amiga enthusiast back in the day, the chances are you had an Amiga 500, and lusted after a 2000 or maybe later a 3000. Later still perhaps you had a 600 or a 1200, and your object of desire became the 4000. The amusingly inept Commodore marketing department repackaged what was essentially the same 68000-based Amiga at the bottom end of the range through the platform’s entire lifetime under their ownership, with a few minor hardware upgrades in the form of chipset revisions that added a relatively small number of features.

We’ve probably listed above all the various Amigas you’ll be familiar with, with a few exceptions you either didn’t have or only saw in magazines. The original A1000, the chipset-upgraded A500+, the CDTV multimedia platform, or the CD32 games console as examples. But there’s one we haven’t listed which you may never have seen unless you hail from the United Kingdom, and it’s an Amiga behind which lies a fascinating tale that has been unearthed by [RetroManCave].

In the late 1980s, Commodore sold the A500 all-in-one cased Amiga to consumers with marketing based heavily upon gaming, and the A2000 desktop Amiga to businesses with the promise of productivity software. Both machines had a 16-bit Motorola 68000 running at the same speed, with the A2000 having a lot of extra memory and a hard drive lurking within that case. The price difference between the two was inordinately high, creating a niche for an enterprising British company called Checkmate Computers to fill with their provocatively named A1500, a clever case for an A500 mainboard that gave it an expansion slot and space for that hard drive and memory.

This machine’s existence angered Commodore, to the extent that they vowed to eradicate the upstart by releasing their own UK-only A1500. The result, a comically badly concealed rebadge of an A2000 with two floppies and no hard drive, is something we remember seeing at the time, and dare we admit it, even lusting after. But the full story in the video below is well worth a watch for an engrossing insight into a little-known saga in one corner of the computing world during the 16-bt era. Towards the end it becomes a plug for the Checkmate Computers co-founder’s current Kickstarter project, but if that holds no interest for you then you are at least forewarned.

Of course, if you have either A1500 today, you might want an up-to-date graphics card for it.

An Amiga 600 With An FPGA Inside

July 10, 2018 by Jenny List 24 Comments

The Amiga is the platform that refuses to die. It must be more than two decades since the debacle surrounding the demise of the original hardware, yet the operating system is still receiving periodic updates, you can still buy Amiga hardware now sporting considerably more powerful silicon than the originals, and its worldwide community is as active as ever.

One of those community projects is the MiSTer FPGA Amiga-on-an-FPGA, and it was this that caught the attention of [Mattsoft]. Impressed with the quality of its recreation of an Amiga, he decided to turn his into a “real” Amiga, so found an Amiga 600 case and keyboard, and set to work. Into the mix went the Terasic DE10-Nano FPGA board, I/O and RAM boards, a Tynemouth Software keyboard interface, a USB hub, and some well-designed 3D-printed parts allow the original Amiga case to be used without modifications.

The Amiga 600 was the base model in the final Amiga range from the early 1990s, and at the time despite its HDD interface and PCMCIA slot it languished in the shadow of its Amiga 1200 sibling. The styling has aged well though, and this upgrade certainly breathes a little life back into the case if not strictly the machine itself. If you want to learn a bit more about MiSTer then a look at the project’s wiki is in order. Perhaps you don’t have an Amiga though and would like to wallow in a bit of nostalgia without splashing out for hardware, in that case, give AROS a look.

Thanks [intric8] for the tip.

Hackaday Links: Some Sort Of Fool’s Day, 2018

April 1, 2018 by Brian Benchoff 20 Comments

A few years ago, writing for a blog called Motherboard of all things, [Emanuel Maiberg] wrote PC Gaming Is Still Way Too Hard. The premise is that custom building a gaming PC is too hard, because you have to source components and comparison shop. Again, this was written for Motherboard. Personally, I would have shopped that story around a bit more. Now, the same author is back again, telling us PC Building Simulator is way more fun than building a real computer. It’s my early nomination for worst tech article of the year.

Speaking of motherboards, This is a GoFundMe project to re-create the Amiga 4000 mainboard, with schematics. Building PCs is too hard, but the Amiga architecture is elegant. Some of these boards are dying due to electrolytic capacitor and battery leakage. This project is aiming to deconstruct an original A4000 board and turn it into Gerbers and schematics, allowing new boards to be manufactured. Building a PC is way too hard, but with this GoFundMe, you won’t have to design an entire system from scratch. Don’t worry, I already tipped off the Motherboard editors to this one.

Alright, story time. In 6th grade science class, the teacher was awesome. On the days when there was really no chance of any learning happening (the day before Christmas break, the last day of school), the teacher broke out the Electric Chicken. What’s an Electric Chicken? It’s a test tube rack, two wires, and a Wimshurst generator. “Here, grab ahold of this for as long as you can.” It got even cooler when you get a bunch of kids to hold hands and tell them pride is better than pain. Here’s a Kickstarter for a mini Wimshurst generator. It’s made out of PCBs! Hat tip to [WestfW] for finding this one.

It’s no secret that I get a lot of dumb press releases. Most of these are relegated to the circular file folder. It’s also no secret I get a lot of ICO announcements hitting my email. These, also, are trashed. I recently received a press release for an ICO that goes beyond anything else. ONSTELLAR is a blockchain-powered social media network for paranormal and metaphysical enthusiasts. It’s the crypto for Coast to Coast AM listeners, UFO enthusiasts, and people who think PKE meters are real. This is it, we’ve reached peak crypto.

If you want to decapsulate an IC — and why wouldn’t you? — the usual way of doing things involves dropping acid, ego death, toxic chemicals, and a fume hood. There is another way. Here’s [A Menadue] decapping a quartz watch IC with just fire. The process is about as ‘hold my beer’ as you would expect. Just take a small butane torch, heat up a chip, and recover the die. A bit of ultrasonic cleaning later and you get a pretty clean chip. Microscope not included.

An Amiga 500 For The 21st Century

March 25, 2018 by Jenny List 26 Comments

There was a period in the late 1980s when the home computer to own did not come with an Apple logo and was not an IBM, Compaq, or any of the other clones, but instead sported a Commodore logo. The Amiga 500 was an all-in-one console-style cased machine that maybe wasn’t quite the computing powerhouse you might have wished it to be, but gave you enough of the capabilities of the more accomplished 16-bit machines of the day to be an object of desire while also having a games catalogue second to none.

A500s have survived in reasonable numbers, but inevitably working A500s haven’t. Fortunately there are decent emulators, and it was for one of these that [intric8] has produced an extremely well-done installation of a Raspberry Pi 3 in an Amiga case. The intention has been throughout to avoid modification or damage to the Amiga case, and eventually to have all Amiga internal peripherals including the floppy drive in a fully working condition.

The result has a Tynemouth Software USB adaptor for the Amiga keyboard, and a set of nicely designed 3D printed backplates to bring the extended Raspberry Pi ports to the back of the case. The floppy isn’t yet interfaced and there isn’t a socket for the quadrature mouse, but otherwise it’s a very tidy build. He might be interested in one of the several USB to quadrature interfaces we’ve featured over the years.

You might ask why so much effort should be put in for an emulation of an A500, and in a sense you’d be right to do so. The Pi will run the emulator from any case or none. But if you happen to have a spare A500 case, why not give this one a go!

Converting Power Supplies For Antique Computers

March 22, 2018 by Bryan Cockfield 16 Comments

Just because something is “never used” doesn’t mean it’s good. [Inkoo Vintage Computing] learned that lesson while trying to repair an Amiga 500 and finding parts online that were claimed to be “new” in that they were old stock that had never been used. The problem was that in the last 30 years the capacitors had dried out, rendering these parts essentially worthless. The solution, though, was to adapt a modern PSU for use on the old equipment.

The first hurdle to getting this machine running again was finding the connector for the power supply. The parts seemed to have vanished, with some people making their own from scratch. But after considering the problem for a minute longer they realized that another Commodore machine used the same parts, and were able to source a proper cable.

Many more parts had to be sourced to get the power supply operational, but these were not as hard to come across. After some dedicated work with the soldering iron, the power supply was put to use running the old Amiga. Asture readers will know that [Inkoo Vintage Computing] aren’t strangers to the Amiga. They recently were featured with a nondestructive memory module hack that suffered from the same parts sourcing issues that this modification had, but also came out wonderfully in the end.

“The Commodore Story” Documentary Premieres Today

February 23, 2018 by Dan Maloney 49 Comments

What is it about a computer that was introduced 36 years ago by a company that would be defunct 12 years later that engenders such passion that people still collect it to this day? We’re talking about the Commodore 64, of course, the iconic 8-bit wonder that along with the other offerings from Commodore International served as the first real computer to millions of us.

There’s more to the passion that Commodore aficionados exhibit than just plain nostalgia, though, and a new documentary film, The Commodore Story, seeks to explore both the meteoric rise and fall of Commodore International. Judging from the official trailer below, this is a film anyone with the slightest interest in Commodore is not going to want to miss.

It will of course dive into the story of how the C64 came to be the best selling computer in history. But Commodore was far from a one-trick pony. The film traces the history of all the Commodore machines, from the PET computers right through to the Amiga. There are interviews with the key players, too, including our own Bil Herd. Bil was a hardware engineer at Commodore, designing several machines while there. He has shared some of these stories here on Hackaday, including the development of the C128 (successor to the C64) and making the C64 speak.

We can’t wait to watch this new documentary ~~and luckily we won’t have to~~. It’s set to start streaming on Netflix, Amazon, and iTunes ~~today, so pop up some popcorn and settle in for a two-hour ride through computer history~~ but right now we’re unable to get firm dates on when. However, those of you in the Mountain View area have an even better opportunity this evening.

The Commodore Story will be premiered live at 6:30pm PST at the Computer History Museum. Grab your tickets to the premiere and a Q&A session with Bil Herd, Leonard Tramiel, and Hedley Davis.

Resurrecting An Amiga CD32

February 16, 2018 by Richard Baguley 15 Comments

As an editor on Amiga magazines in a previous life, this is kind of bittersweet. [RetroManCave] was donated an Amiga CD32 games system, and it is trying to resurrect it. If you’ve not heard of it, the CD32 was a 1993 games console based on the Amiga home computer system. It was the last gasp for Commodore, the beleaguered company behind the Amiga. In this first video of a series, they take the system apart, take you through what’s inside and boot it up. The system boots, but there is some sort of problem with the video sync, and they will be taking a closer look at fixing that next. We have featured a couple of similar projects from [RetroManCave] before, such as their brain transplant on a Big Trak toy and Commodore 64 fix. This video (after the break) is worth a watch if you are curious about old systems like this, want some tips on resurrecting old hardware or just want to shed a tear as your misspent youth is torn apart before your eyes.
