Books You Should Read: Bil Herd’s Back Into The Storm

September 8, 2021 by Jenny List 27 Comments

It’s a morning ritual that we guess most of you share with us; before whatever work a new day will bring to sit down with a coffee and catch up with the tech news of the moment on Hackaday and other sites. Most of us don’t do many exciting things in our everyday lives, so reading about the coolest projects and the most fascinating new developments provides us with interest and motivation. Imagine just for a moment then that by a twist of fate you found yourself taking a job at the epicentre of the tech that is changing the world, producing the objects of desire and pushing the boundaries, the place you’d give anything to work at.

This is the premise behind our Hackaday colleague Bil Herd’s autobiographical chronicle of time in the mid 1980s during which he worked at Commodore, maker of some of the most iconic home computers of the day. We follow him through the three years from 1983 to 1986 as hardware lead on the “TED” series of computers including the Commodore 16 and Plus/4, and then the Commodore 128, a dual-processor powerhouse which was arguably the last of the big-selling 8-bit home computers.

It’s an intertwined set of narratives peppered with personal anecdotes; of the slightly crazy high-pressure world of consumer videogames and computing, the fine details of designing a range of 8-bit machines, and a fascinating insight into how the culture at Commodore changed in the period following the departure of its founder Jack Tramiel.

Commander X16: A Dreamy 8 Bit Computer Comes Closer To Reality

August 18, 2021 by Ryan Flowers 32 Comments

Imagine the ultimate homage to 1980s 8-bit home computers. It might look like [David Murray] aka The 8-Bit Guy’s Commander X16.

As a core group of geeks, hackers, and developers age, we yearn for the computers of our youth. VIC-20s, Commodore Pets, 64s, 128s, Ataris, Apple IIes, and the list goes on and on. For many of us, our first hands on experience with a computer was with such a machine that is now called “retro”. Sadly, many of these relics are getting more expensive as demand increases and supplies dwindle. Working examples are harder to find, and even those can break down. Original monitors, peripherals, and accessories are also getting scarcer. This is all quite understandable when we consider that some of these classics are over 40 years old.

What was it that we loved about these old rigs that makes them so attractive? [David] decided to distil what makes a classic a classic, and then turn that list into a spec list for what he calls his “Dream Computer”. He found that things like a printed and spiral bound manual were a big part of the charm and utility of these early home computers. Booting directly to a prompt and being able to directly control the hardware was another highly desirable trait.

[David] also took the time to determine what people don’t like about these retro machines: Wacky keyboard layouts, composite video output, and glacially slow storage. Swapping multiple floppies to load a program or respooling a cassette tape is just as undesirable in 2021 as it was in 1981. Who knew?

X16 Prototype #3 — The X16’s’ prototyping is still in progress.

The result of [David]’s research is the Commander X16. Inspired by the VIC-20, it’s a fresh take on the retrocomputer that only uses parts that are currently available. You can see the first video in a series about the development of the X16 below the break. Be aware that a lot of progress has been made since the video came out in 2019, but it still provides an excellent starting point for learning about the project.

The X16’s specifications read like dream list made in the mid 80s: 256 color VGA, up to 2MB memory, an 8 MHz 6502, plenty of expansion ports, and even ports for SNES style controllers. And what else will this dream machine include? You guessed it: A spiral bound manual!

It’s not possible to list all of the great features of the X16 in this space, so check out the Commander X16 FAQ for all the details. If this project makes your heart go pitter patter, you may be interested to know that they need help with software development! An emulator is available for development. The goal is to have a healthy software ecosystem in place when the X16 launches.

You may also enjoy reading about other 6502 retrocomputer reports such as this “Brain in a vat” 6502 computer, or a guided tour of the birthplace of the 6502 and the Commodore 64 with our very own Bil Herd.

Thank you to [Truth] for bringing us a report of this fine project via the Tip Line. Keep those tips coming!

Retrotechtacular: Amiga Pips The PC For Mission-Critical Computing At NASA

August 16, 2021 by Chris Wilkinson 42 Comments

In 1986, a group of NASA engineers faced a difficult choice in solving their data processing woes: continue tolerating the poor performance of PC architecture, or pony up the cash for exotic workstations. It turns out that the Commodore Amiga was an intriguing third choice, except for the fact that, paradoxically, it didn’t cost enough. Oh, and Apple wanted nothing to do with any of it.

Steeped in history, NASA’s Hangar AE is a hub for launch vehicle telemetry and other mission communications, primarily during prelaunch phases for launches at Cape Canaveral. Throughout the late 20th century, Hangar AE supported NASA launch vehicles in all shapes and sizes, from the Atlas-Centaur evolutions to the mighty Titan family. It even supported user data from the Space Shuttle program. Telemetry from these missions was processed at Hangar AE before being sent out to other NASA boffins, and even transmitted worldwide to other participating space agencies.

Coming down from decades of astronomical levels of funding, the 1980s was all about tightening the belt, and NASA needed budget solutions that didn’t skimp on mission safety. The Commodore Amiga turned out to be the right choice for processing launch vehicle telemetry. And so it was still, when cameras from the Amiga Atlanta group were granted permission to film inside Hangar AE.

Yo Dawg, We Heard You Like Retrocomputers

August 14, 2021 by Bryan Cockfield 20 Comments

The idea of having software translation programs around to do things like emulate a Super Nintendo on your $3000 gaming computer or, more practically, run x86 software on a new M1 Mac, seems pretty modern since it is so prevalent in the computer world today. The idea of using software like this is in fact much older and easily traces back into the 80s during the era of Commodore and Atari personal computers. Their hardware was actually not too dissimilar, and with a little bit of patience and know-how it’s possible to compile the Commodore 64 kernel on an Atari, with some limitations.

This project comes to us from [unbibium] and was inspired by a recent video he saw where the original Apple computer was emulated on Commodore 64. He took it in a different direction for this build though. The first step was to reformat the C64 code so it would compile on the Atari, which was largely accomplished with a Python script and some manual tweaking. From there he started working on making sure the ROMs would actually run. The memory setups of these two machines are remarkably similar which made this slightly easier, but he needed a few workarounds for a few speed bumps. Finally the cursor and HMIs were configured, and once a few other things were straightened out he has a working system running C64 software on an 8-bit Atari.

Unsurprisingly, there are a few things that aren’t working. There’s no IO besides the keyboard and mouse, and saving and loading programs is not yet possible. However, [unbibium] has made all of his code available on his GitHub page if anyone wants to expand on his work and may also improve upon this project in future builds. If you’re looking for a much easier point-of-entry for emulating Commodore software in the modern era, though, there is a project available to run a C64 from a Raspberry Pi.

Thanks to [Cprossu] for the tip!

Inside The VIC-20

May 19, 2021 by Al Williams 48 Comments

Commodore machines are well-loved around here, but usually when you think Commodore, you think about the Commodore 64, or maybe the PET or Amiga. But the Commodore 64 had an older sister, the VIC 20. This was the first computer to sell a million units and has a lot in common with its better-known successor. The machine was only made for a few years, and [Dubious Engineering] has been restoring one over a few videos. In the video below, he opens it up for a look inside, among other things.

If you want to get straight to the opening, you’ll need to fast forward about 5 and a half minutes. The keyboard pulls off and a nice old-fashioned set of cables made from individual wires connect to the skinny main board with all the smarts on it. No ribbon cables or flex PCBs!

Hackaday Links: May 9, 2021

Well, that de-escalated quickly. It seems like no sooner than a paper was announced that purported to find photographic evidence of fungi growing on Mars, that the planetary science and exobiology community came down on it like a ton of bricks. As well they should — extraordinary claims require extraordinary evidence, and while the photos that were taken by Curiosity and Opportunity sure seem to show something that looks a lot like a terrestrial puffball fungus, there are a lot of other, more mundane ways to explain these formations. Add to the fact that the lead author of the Martian mushroom paper is a known crackpot who once sued NASA for running over fungi instead of investigating them; the putative shrooms later turned out to be rocks, of course. Luckily, we have a geobiology lab wandering around on Mars right now, so if there is or was life on Mars, we’ll probably find out about it. You know, with evidence.

If you’re a fan of dystopic visions of a future where bloodthirsty robots relentlessly hunt down the last few surviving humans, the news that the New York Police Department decided to stop using their “DigiDog” robot will be a bit of a downer. The move stems from outrage generated by politicians and citizens alike, who dreamt up all sorts of reasons why the NYPD shouldn’t be using this tool. And use it they apparently did — the original Boston Dynamics yellow showing through the many scuffs and dings in the NYPD blue paint job means this little critter has seen some stuff since it hit the streets in late 2020. And to think — that robot dog was only a few weeks away from filing its retirement papers.

Attention, Commodore fans based in Europe: the Commodore Users Europe event is coming soon. June 12, to be precise. As has become traditional, the event is virtual, but it’s free and they’re looking for presenters.

In a bid to continue the grand Big Tech tradition of knowing what’s best for everyone, Microsoft just announced that Calibri would no longer be the default font in Office products. And here’s the fun part: we all get to decide what the new default font will be, at least ostensibly. The font wonks at Microsoft have created five new fonts, and you can vote for your favorite on social media. The font designers all wax eloquent on their candidates, and there are somewhat stylized examples of each new font, but what’s lacking is a simple way to judge what each font would actually look like on a page of English text. Whatever happened to “The quick brown fox” or even a little bit of “Lorem ipsum”?

And finally, why are German ambulances — and apparently, German medics — covered in QR codes? Apparently, it’s a way to fight back against digital rubberneckers. The video below is in German, but the gist is clear: people love to stop and take pictures of accident scenes, and smartphones have made this worse, to the point that emergency personnel have trouble getting through to give aid. And that’s not to mention the invasion of privacy; very few accident victims are really at their best at that moment, and taking pictures of them is beyond rude. Oh, and it’s illegal, punishable by up to two years in jail. The idea with the QR codes is to pop up a website with a warning to the rubbernecker. Our German is a bit rusty, but we’re pretty sure that translates to, “Hey idiot, get back in your frigging car!” Feel free to correct us on that.

[Editor’s note: “Stop. Rubbernecking kills”.]

Commodore 64 Emulator In VR Delivers A Full 80s Experience

May 3, 2021 by Donald Papp 18 Comments

The simulated color CRT monitor looks surprisingly convincing in VR.

One way to play with vintage hardware without owning the hardware is to use an emulator, but [omni_shaNker] announced taking it to the next level by using VR to deliver a complete Commodore 64 system, in its full glory, complete with a native 80s habitat playset! This is a pretty interesting angle for simulating vintage hardware, especially since the emulator is paired with what looks like a pretty convincing CRT monitor effect in VR, not to mention a virtual 5.25″ floppy drive that makes compellingly authentic sounds.

The project is hosted on GitHub and supports a variety of VR hardware, but for owners of Oculus headsets, the application is also available on SideQuest for maximum convenience. SideQuest is essentially an off-the-books app store for managing software that is neither approved nor distributed by Facebook. Oculus is owned by Facebook, and Facebook is keen to keep a tight grip on their hardware.

As functional as the application is, there are still improvements and optimizations to be made. To address this, [omni_shaNker] put out a call for beta testers on Reddit, so if that’s up your alley be sure to get in touch. A video demonstration and overview that is chock-full of technical details is also embedded below; be sure to give it a watch to see what the project is all about.
