This weekend it’s all going down at the Vintage Computer Museum in Mountain View, California. The Vintage Computer Festival West is happening this weekend
What’s going on this year at VCF West? Far too much. The exhibits include everything from floptical disks, a fully restored and operation PDP-11/45, home computers from the UK and Japan, typewriters converted into teletypes, a disintegrated CPU, and LISP machines. The talks are equally spectacular, with a keynote from [Tim Paterson], the creator of 86-DOS, the basis of MS-DOS. You’ll also hear about PLATO, the Internet before the Internet, PDP-1 demonstrations, and if we’re lucky they’re going to fire up the ancient IBM 1401. There will also be a vintage computer consignment, which is at least as interesting as the exhibits. The consignment is basically a museum, but you can buy the exhibits.
VCF West is happening this weekend at the Computer History Museum in Mountain View, itself a worthy destination for a day trip. For one weekend a year, though, the Computer History Museum is taken over by VCF attendees and becomes the greatest place to learn about this history of computing. They even have one of those Waymo bug cars in their autonomous vehicle exhibit.
All of this is going down this Saturday and Sunday, starting at 9am. Tickets are $20 for one day, $30 for the entire weekend, and yes, that includes admission to the Computer History Museum. Don’t miss out!
While the weather alternated between mist and monsoon for most of it, the thirteenth annual Vintage Computer Festival East was still a huge success. People came from all over the country, and indeed the world, to show off computers and equipment that was easily older than many of those in attendance. From 1980’s robots to recreations of the very first machines to ever carry the name “computer” as we understand it today, there were a dizzying array of fascinating exhibits to see for those who made the pilgrimage to the InfoAge Science Center in Wall, New Jersey. The people who own and maintain these technological touchstones were in many cases were just as interesting as the hardware they brought to show off; walking encyclopedias of knowledge about the particular piece of vintage gear that they’ve so lovingly shepherded into the modern day.
Through it all, save for a brief intermission to get chili dogs from the nearest WindMill, Hackaday was there. We got up close and personal with [Brian Stuart]’s impressive ENIAC emulator, listened to some ethereal chiptunes courtesy of [Bill Degnan]’s MITS Altair 8800, saw relics from the days when the “app store” needed stamps from [Allan Bushman]’s impressive colleciton, and got inspired by the [Alexander Pierson]’s somewhat more modern take on the classic kit computers of the 1970’s.
But those were’t the only things on display at the Vintage Computer Festival, not by a long shot. There were over 100 individual exhibits this year at VCF, and that doesn’t even include the workshops, classes, tours, or the daily keynote presentations. To say you get your money’s worth on the ticket is something of an understatement.
It’s fair to say that there’s no real substitute for seeing a show like this in person. But in addition to the aforementioned articles, a rundown (in no particular order) of some of the interesting exhibits and attractions from this year’s VCF is a decent consolation prize. If this piques your interest, we’d invite you to keep an eye out for the next Vintage Computer Festival. We’ll be there.

Among the rows of digital dinosaurs, one blinking front panel stood out. It certainly looked the part of a retro computer; with banks of blinking LEDs and multicolored paddle switches. But upon closer inspection, the laser cut wooden front panel betrays the fact that this machine is an impostor. It may have the appearance of a machine from the heady days where home computers looked like they could have doubled as a prop on the bridge of Kirk’s Enterprise, but it’s actually a product of much more modern provenance.
It’s called the Cactus, a love letter to the homebrew microcomputers of the 1970’s, designed and built by somebody at least 20 years too young to have experienced them the first time around. Alexander Pierson created the Cactus not because he had fond memories of putting together an Altair 8800 in 1975, but because he’s fascinated with the retro computer experience: the look of the front panel, the satisfying clunk of era-appropriate switches, and the idea that the computer’s inner workings aren’t an abstract black box but rather something you can interact with and study. Judging by all the attention the Cactus got at VCF East XIII, he’s not the only one.
Let’s take a look at everything Alexander poured into this retrocomputer build.

You’d be forgiven if you thought software defined radio (SDR) was a relatively recent discovery. After all, few outside of the hardcore amateur radio circles were even familiar with the concept until it was discovered that cheap USB TV tuners could be used as fairly decent receivers from a few hundred MHz all the way up into the GHz range. The advent of the RTL-SDR project in 2012 brought the cost of entry level SDR hardware from hundreds of dollars to tens of dollars effectively overnight. Today there’s more hackers cruising the airwaves via software trickery than there’s ever been before.

Today we take the concept of a centralized software repository for granted. Whether it’s
apt or the App Store, pretty much every device we use today has a way to pull applications in without the user manually having to search for them on the wilds of the Internet. Not only is this more convenient for the end user, but at least in theory, more secure since you won’t be pulling binaries off of some random website.
But centralized software distribution doesn’t just benefit the user, it can help developers as well. As platforms like Steam have shown, once you lower the bar to the point that all you need to get your software on the marketplace is a good idea, smaller developers get a chance to shine. You don’t need to find a publisher or pay out of pocket to have a bunch of discs pressed, just put your game or program out there and see what happens. Markus “Notch” Persson saw his hobby project Minecraft turn into one of the biggest entertainment franchises in decades, but one has to wonder if it would have ever gotten released commercially if he first had to convince a publisher that somebody would want to play a game about digging holes.
In the days before digital distribution was practical, things were even worse. If you wanted to sell your game or program, it needed to be advertised somewhere, needed to be put on physical media, and it needed to get shipped out to the customer. All this took capital that would easily be beyond many independent developers, to say nothing of single individuals.
But at the recent Vintage Computer Festival East, [Allan Bushman] showed off relics from a little known chapter of early home computing: the Atari Program Exchange (APX). In a wholly unique approach to software distribution at the time, individuals were given a platform by which their software would be advertised and sold to owners of 8-bit machines such as the Atari 400/800 and later XL series computers. In the early days, when the line between computer user and computer programmer was especially blurry, the APX let anyone with the skill turn their ideas into profit.

The ENIAC, or Electronic Numerical Integrator and Computer, is essentially the Great Great Grandfather of whatever device you’re currently reading these words on. Developed during World War II for what would be about $7 million USD today, it was designed to calculate artillery firing tables. Once word got out about its capabilities, it was also put to work on such heady tasks as assisting with John von Neumann’s research into the hydrogen bomb. The success of ENIAC lead directly into the development of EDVAC, which adopted some of the now standard computing concepts such as binary arithmetic and the idea of stored programs. The rest, as they say, is history.
But ENIAC wasn’t just hugely expensive and successful, it was also just plain huge. While it’s somewhat difficult for the modern mind to comprehend, ENIAC was approximately 100 feet long and weighed in at a whopping 27 tons. In its final configuration in 1956, it contained about 18,000 vacuum tubes, 7,000 diodes, 70,000 resistors, 10,000 capacitors, and 6,000 switches. All that hardware comes with a mighty thirst for power: the ENIAC could easily suck down 150 kW of electricity. At the time this all seemed perfectly reasonable for a machine that could perform 5,000 instructions per second, but today an Arduino would run circles around it.
This vast discrepancy between the power and size of modern hardware versus such primordial computers was on full display at the Vintage Computer Festival East, where [Brian Stuart] demonstrated his very impressive ENIAC emulator. Like any good vintage hardware emulator, his project not only accurately recreates the capabilities of the original hardware, but attempts to give the modern operator a taste of the unique experience of operating a machine that had its heyday when “computers” were still people with slide rules.

The pitch to my wife was simple: “Feel like spending the weekend in Seattle?” That’s how I ended up at the inaugural Vintage Computer Festival Pacific Northwest last weekend, and I’m glad we made the five-hour drive into The Big City to check it out. Hackaday is a VCF sponsor, after all, so it seemed like a great excuse to make the trip. That it ended up being two consecutive days of great Seattle weather was only icing on the cake of being able to spend time with fellow retro computer aficionados and their dearest bits of old hardware, in a great museum dedicated to keeping computer history alive and accessible.
The fact that Seattle, home of Microsoft, Amazon, and dozens of other tech companies, has until now been left out of the loop in favor of VCF East in New Jersey and VCF West in Mountain View seems strange, but judging by the reception, VCF PNW is here to stay and poised to grow. There were 20 exhibitors for this go around, showing off everything from reanimated PDP-11 and Altair 8800 control panels to TRS-80s from Model 1 through to the CoCo. Almost every class of reasonably transportable retro hardware was represented, as well as some that pushed the portability envelope, like a working PDP-8 and a huge Symbolics 3640 LISP workstation.
