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.
A Truck Computer, Sans Truck
Today we think of mobile computing as being a tablet, smartphone, or maybe even a laptop. But in 1956 when the United States Army made its request for a mobile computer, the goal was to build a computer that could be transported by truck to the front lines of a battlefield. Considering computers up to this point took up whole buildings, it was a fairly tall order.
In the end, Sylvania won the bid and built the “MOBIle DIgital Computer”, or MOBIDIC. The computer was housed in a thirty foot long trailer, and consumed so much energy that a second truck containing a generator had to follow it around. For good measure, two more vans were added to the convoy, one holding spare parts and another a repair shop. It was a far cry from your laptop as far as mobile computers go, but it was still pretty good for the era.
[Jeff Salzman] has been fascinated with the MOBIDIC for years, and is currently working on an emulator to bring its unique architecture back to life. As the MOBIDIC was designed at the Camp Evans Signal Laboratory, which is now the home of InfoAge and VCF East, there’s even talk of getting an old Army trailer and building a life-size exhibit to show visitors what it would have been like to work inside of MOBIDIC. At this point [Jeff] is still in the very early stages and was mainly presenting information on how the computer worked and his research, but it all sounds very promising. Definitely a project to keep an eye on.
Commodore 64 Photo Booth
There’s nothing like being in a room full of pre-1980 computers to remind you of just how far technology has come in what’s really an exceptionally short amount of time. Pretty much any exhibit at the show was a sharp contrast to the smartphones most of us now carry, but perhaps the most succinct of them was the “8-Bit Digital Portraits” table run by [Jeffrey Brace].
Using an old Panasonic CCTV camera, a Commodore 64, and a relatively rare product called “ComputerEyes”, [Jeffery] would take pictures of willing participants and then print them out on a Star NX-1000 dot matrix printer as a memento. For younger attendees, the whole process was something of a culture shock. With relatively high-end cameras in every smartphone on the market, we take for granted the ability to take a multi-megapixel image on a whim.
As an interesting aside, the person getting their picture taken by the Commodore when I stopped by the table was [John Sutley], whose work involving the restoration of vintage CRT monitors we’ve covered here on Hackaday before.
The BBS Experience
You can read about the heyday of bulletin board system (BBS), you can even “dial” into some modern ones over the internet, but there’s nothing quite like using a BBS on vintage hardware and at vintage speeds. Just in case anyone forgot what it was like actually sending messages on one of these systems back when they were all the rage, [Michael Lee] brought in some era appropriate hardware for attendees to use while chatting on the Diversi-Dial BBS.
An Apple IIe was running as the host, sporting Hayes MicroModems for connectivity. On the client side DEC VT-100 and 220 terminals were on hand, complete with acoustic couplers. Even for show-goers who were
old experienced enough to have used dial-up connections or chatted on the original BBS were shocked to be confronted with the tech again after all these years. Watching messages get typed out character by character got more than a few chuckles from those in attendance. Nostalgia has a funny way of making things seem a lot better than they were.
While the actual Vintage Computer Festival East only happens once a year at InfoAge, the Vintage Computer Federation maintains a computer museum there year round which contains an absolutely incredible amount of hardware. From the monstrous Univac 1219-B mainframe recovered from the U.S. Navy to essentially every significant desktop computers from the 80s and 90s, there’s really something for everyone in the collection.
Many of the desktop computers are powered up and can be used by visitors, though naturally under supervision by a staffer. Demonstrations are given for the mainframes, allowing those in attendance a chance to see these behemoths at work. Really a must-see collection if you’re interested in computer history and within reasonable distance of the Jersey shore.
The consignment room was an absolute treasure trove, with a wide array of items and in some cases preposterously low prices. Those bringing their old hardware to get sold at VCF are obviously in it more to keep the stuff out of a landfill than they are to make a profit for themselves. Respect.
Like the rest of VCF, the consignment room featured an incredible number of things to check out, though there were some standouts. This HP 64000 Logic Development System, complete with crates of documentation and adapters for chips such as the Z80 and 8088 is a particularly good example of something you’re not likely to see anywhere else:
Not everything for sale was an old computer either. From classic gaming to test equipment, there were plenty of deals to be had.
Not to be confused with the consignment area which was staffed by volunteers, the vendor room was were professional sellers had their wares on display. Here you could find newly manufactured kit computers and electronic gear. Even a few Raspberry Pis were spotted. The vintage hardware that was available in the vendor area was also a bit higher up the scale in terms of condition, but as expected, so to were the prices.
Garnering particular interest in the vendor area was the table for Corsham Tech, which was showing off a very slick KIM-1 clone, as well as new manufactured accessories for the original machine:
The Vintage Computer Festival East XIII was an amazing event, but like all good things, it too had to come to an end. But don’t despair, there’s more vintage computing where that came from. VCF East may be gone until next year, but VCF West will be taking place August 4th and 5th in Mountain View, California. If your next ideal system-upgrade is a paper tape reader, and you can get out to the somewhat less dreary side of the United States, we’d strongly recommend you check it out.
