VCF East 2023: Retro Luminaries Take The Stage

Our friend [Fran Blanche] recently recorded what it was like to participate in an energetic round table at the recently held Vintage Computer Festival (VCF) East. Fran joined well known personalities [Jeri Ellsworth], [Adrian Black] of Adrian’s Digital Basement, and Usagi Electric creator [Dave Lovett] with yours truly moderating.

The table-less roundtable discussed the pros and cons of streaming about retro and tech, and what its like to hang yourself out there in video format. Goals and motives differed widely from speaker to speaker and there was some good-natured ribbing about who makes money vs. who simply gets away with spending less.

Most of all fun was had by the speakers as they interacted with each other, and with the audience — and that comfort came across to the standing room only crowd of avid retro-enthusiasts who only told us good things about what they saw and heard that night.

One thing we did note was that every speaker actually knew what microphones were and how to use them.

Vintage Computer Festival East Was A Retro Madhouse

The Vintage Computer Festival East took place last weekend at the InfoAge Science and History Museum in New Jersey, and by any metric you care to use, it was a phenomenal success. Everyone you spoke with, from the the exhibitors and attendees, to the veteran volunteers who put this incredible show together, all said the same thing: they’d never seen a turnout like this before.

Of course, such success is not without cost. The exhibit rooms were so packed that moving through them was a challenge, the line to get food or browse the consignment area occasionally stretched outside the building, and at one point the event’s electronic payment system buckled under the pressure.

Some things are worth the wait.

Yet even the folks who waited the better part of an hour to rummage through boxes of dusty treasures, only to find themselves left standing with armfuls of heavy gear they couldn’t pay for until the technical issues were resolved couldn’t really complain. I should know, I was one of them. It would be like going to a concert and getting upset that the music was too loud — the event was advertised as a festival, and that’s exactly what it was.

No matter where you went, you’d find throngs of excited people who were eager to chat about the golden age of computing. So even if you were stuck in a long line, or had to step outside of the exhibit area to get some fresh air, you were always in excellent company. Seeing such a large and diverse number of people come out for what’s ultimately a niche event was exceptionally gratifying. At the end of the day, if the price we have to pay for this kind of community response is a few long lines and tight squeezes, it’s well worth it.

Each time I cover an event like this for Hackaday, I do so with the caveat that there’s really no substitute for being there in person. No matter how many articles you read and YouTube recaps you watch, you’ll never be able to see all the things you would have had you been able to walk the show floor yourself. It’s a bit like exploring the Moon or Mars: remotely controlled robots are capable of capturing terabytes of data and beaming it back to Earth, but even still, there’s the potential to learn so much more by putting boots on the ground.

The same is true of VCF East 2023 — what I bring you here is just the tip of the iceberg in terms of what was on display at this year’s event. On the other hand, you have the advantage of being able to peruse these images without having to stand in line. Is it worth the trade? Only you can be the judge of that. But for my money, I’ll gladly get back in line when VCF East 2024 rolls around.

Vintage Computer Festival East Returns This Weekend

Spring has sprung at the Jersey Shore, and for retrocomputer aficionados that can only mean one thing — the Vintage Computer Festival East is imminent. The East Coast’s premier event for classic computers and associated electronics kicks off tomorrow at the InfoAge Science and History Museum in Wall, NJ, and continues until Sunday. If you’re in the Northeast United States, and frankly, even if you aren’t, you’d be hard-pressed to find a better opportunity to experience the unique charms of early computer technology.

VCF East is three days of talks, workshops, and exhibits focusing on computers of a bygone area. For the uninitiated, that might seem like an odd thing to fixate on. But those who’ve visited a VCF event in the past know just how fascinating the technology of this era can be. You’ll see first-hand not only the unique machines that never quite caught on with the mainstream but the pioneering software and hardware engineering that laid the groundwork for our modern way of life. Plus, a little bit of everything in between. Just take a look at this year’s schedule; even the most experienced of graybeards would have a hard time walking away from VCF East without knowing a bit more than when they came in.

Part of what makes the Vintage Computer Festival so great is right in the name — it’s very literally a festival. This isn’t some sterile museum environment where you’re forced to look at a dusty piece of hardware through a half-inch of bulletproof glass. It’s a celebration, and everyone’s invited. Many of the exhibits will give you an opportunity to go hands-on with rare pieces of original hardware, and every presenter you talk to will be more than happy to explain what they’ve come to show off and answer any questions you might have.

In addition to the more educational aspects of VCF, there are also the vendor and consignment areas, which offer a myriad of opportunities to convert your money into devices that whir and blink. From classic gaming systems to unusual components that perhaps only a handful of people in the world could still identify at a glance, the only things you won’t find are the jacked-up prices and shipping costs you’d get from eBay.

Of course, the organizers realize that not everyone can get to the tropical paradise that is New Jersey in April. As such, VCF East will offer an online component that includes an official Discord server and three different live streams for the talks held on Friday, Saturday, and Sunday. That said, there won’t be any streaming video from the show floor itself, so unfortunately, you won’t be able to see any of the exhibits or workshops. That said, you can always count on there being several VCF wrap-up videos posted to YouTube by the usual retrocomputing suspects, to say nothing of the coverage you’ll be seeing on these pages.

Whether you’re there in person or experiencing it vicariously through the videos and articles posted by others, the Vintage Computer Festival East is a can’t-miss event for anyone who has a passion for computers and would like to learn more about how they became what they are today. Hackaday will be there — join us, won’t you?

Supercon 2022: Aedan Cullen Is Creating An AR System To Beat The Big Boys

There’s something very tantalizing about an augmented reality (AR) overlay that can provide information in daily life without having to glance at a smartphone display, even if it’s just for that sci-fi vibe. Creating a system that is both practical and useful is however far from easy, which is where Aedan Cullen‘s attempt at creating what he terms a ‘practical augmented reality device’.

In terms of requirements, this device would need to have a visual resolution comparable to that of a smartphone (50 pixels/degree) and with a comparable field of view (20 degrees diagonal). User input would need to be as versatile as a touchscreen, but ‘faster’, along with a battery life of at least 8 hours, and all of this in a package weighing less than 50 grams.

Supercon 2022: Chris Combs Reveals His Art-World Compatibility Layer

[Chris Combs] is a full time artist who loves using technology to create unique art projects and has been building blinky artwork since about a decade now. In his 2022 Supercon talk “Art-World Compatibility Layer: How to Hang and Sell Your Blinky Goodness as Art” (Slides, PDF), [Chris] takes us behind the scenes and shows us how to turn our blinky doodads in to coveted art works. There is a big difference between a project that just works, and a work of art, and it’s the attention to small details that differentiates the two.

Just like the field of engineering and technology, the art world has its own jargon and requires knowledge of essential skills that make it intimidating to newcomers. It’s not very easy to define what makes an artwork “art” or even “Art”, and sometimes it’s difficult to distinguish if you are looking at a child’s scrawls or a master’s brushstrokes. But there are a few distinguishing requirements that a piece of artwork, particularly one revolving around the use of technology, must meet.

Hackaday Does Berlin

If you’re wondering why there was no newsletter last weekend, it was because we had our hands full with Hackaday Berlin. But boy, was it worth it! Besides being the launch party for the tenth annual Hackaday Prize, it was the first Hackaday gathering in Europe for four years, and it was awesome to see a bunch of familiar faces and meet many more new ones.

In a world that’s so interconnected, you might think that social media can take care of it all for you. And to some extent that’s true! If I could count the number of times I heard “I follow you on Twitter/Mastodon” over the course of the event!

But then there were tons of other meetings. People who are all interested in building and designing analog synthesizers, even some who live in the same urban megalopolis, meeting each other and talking about modules and designs. People who love flip dots. On the spot collaborations of people writing video drivers and people making huge LED walls. And somehow there’s still room for this to happen, even though the algorithms should have probably hooked these folks up by now.

From the perspective of hosting the conference, I get the most satisfaction from seeing these chance meetings and the general atmosphere of people learning not only new things, but new people. This cross-fertilization of friendships and project collaborations is what keeps our community vital, and especially coming out of the Pandemic Years, it’s absolutely necessary. I came away with a long list of new plans, and I’m sure everyone else did too. And for some reason, social media just isn’t a substitute. Take that, TwitFace!

2022 Supercon: Jac And Ralf Explore The Secrets Of The Digital Compact Cassette

During the 1990s, music was almost invariably stored on CDs or cassette tapes. When the new millennium came around, physical formats became obsolete as music moved first to MP3 files, and later to network streams. But a few years before that big transition, there were several attempts at replacing the aging cassette and CD formats with something more modern. You might remember the likes of MiniDisc and Super Audio CD, but there were a few other contenders around.

The Digital Compact Cassette, or DCC, was one such format. Released by Philips in 1992 as a replacement for the analog audio cassette, it failed to gain traction in the market and disappeared before most people had even heard of it. Not so for [Jac Goudsmit] and [Ralf Porankiewicz] however, who have spent years researching all aspects of the DCC system and shared some of the results in their 2022 Supercon talk.

[Ralf] is the curator of the DCC Museum in Cathedral City, California, which owns examples of all DCC equipment ever released, as well as several devices that never made it to market. He also aims to document the history of audio recording and DCC’s contribution to it, which goes further than you might think. For example, the audio compression format used in the DCC system, called PASC, was an early version of what would later become MP3 – though most histories of audio compression ignore this fact.

[Jac], for his part, made an extensive study of all the technical features of the DCC format. He has written numerous articles about his findings, first in the DCC FAQ and later by maintaining the relevant Wikipedia articles. He is running several projects aimed at keeping the format alive, often in collaboration with the DCC Museum.

[Jac] and [Ralf] begin their talk with a brief introduction to the system and its media. DCC players were designed to be compatible with analog audio cassettes, so DCC cartridges are the same basic size, though with a different type of tape inside. Playback devices contain a complex set of magnetic heads to read either the analog signals from classic tapes, or the digital data stored on DCCs.

One unique feature of DCC is Interactive Text Transfer Service, or ITTS, which is a separate data area on the tape that can hold additional information like song lyrics or even simple animations. It was intended to be displayed on players that supported it, but no such devices were ever released. Luckily, [Jac] and [Ralf] managed to find a rare ITTS decoder system used in a tape mastering facility, and were able to reveal the contents of this “secret track”, which is present on all prerecorded tapes, for the first time.

User-recorded tapes never had any ITTS data, and differed from prerecorded ones in several other ways, too. The most obvious difference was that professionally-made tapes could be indexed by song title, while home-made ones could only jump to track numbers. [Jac] and [Ralf] are however working to enable all the professional features on home-made tapes as well, through a number of software and hardware projects.

The most basic software needed is an encoder and decoder for the PASC format, which [Jac] developed from existing MP1 sofware. But to explore some of the more obscure hardware features, he had to reverse-engineer several different DCC players. This led him to discover many interesting half-finished features: the ITTS data sector is one example, but he also found out that some players send ready-to-use VU meter data to their front panel, even though they are unable to display that information.

[Jac] was also one of the first people to buy the DCC-175 portable DCC player when it was released in 1995. This was the only DCC player ever sold with a computer interface, allowing direct transfer of digital audio between a computer and a DCC tape. The parallel port interface and its accompanying Windows 9x software are completely obsolete and unusable with modern PCs, so [Jac] is working on directly accessing the data from the DCC-175 through a custom cable. He’s making good progress: he already figured out the electrical interface and wrote some software that enables him to control the tape recorder directly.

We can’t help but be impressed by the amount of effort both [Jac] and [Ralf] have put into understanding and documenting all the intricacies of a long-obsolete audio format. Thanks to their efforts, we can still appreciate the impressive technology behind DCC – even if it never came close to replacing its analog cousin.
