Next weekend is the Vintage Computer Festival West, held at the Computer History Museum. Hackaday is once again proud to sponsor this event that brings together the people and hardware that drove the information revolution. [Bil Herd] and [Joshua Vasquez] will be on hand representing the Hackaday Crew.
This year’s talks show an impressive lineup of people. [Bil Herd] will be on stage with a collection of other engineers who secured Commodore’s place in history. The Computer History Museum has a very active restoration program for original computer hardware. Friend of Hackaday, [Ken Shirriff], has been working on a restoration of the Xerox Alto and is on the panel giving a talk about the process. And just to cherry-pick one more highlight, there’s a talk on system debugging before you even turn the thing on — a topic that can save you from having a very bad day with very ancient hardware.
A great part of VCF is that the exhibits are often either hands-on or demonstrations so you can actually play around with hardware which most people have never even seen in person. Add to that the collection at the Computer History Museum plus some extra exhibits they have planned for the event and you’re likely to run out of time before you make your way through everything.
Since we’ve mentioned the Computer History Museum, we also have some upcoming news. A bit later this month, Hackaday Contributor-at-Large [Voja Antonic] has been invited to visit the museum, record his oral history, and deliver to their collection an original Galaksija computer — wildly successful first as a kit and then as a manufactured computer which he built in Yugoslavia 1983. Congratualtions [Voja]!
For thirty years, the classic synths of the late 70s and early 80s could not be reproduced. Part of the reason for this is market forces — the synth heads of the 80s didn’t want last year’s gear. The other part for the impossibility to build new versions of these synths was the lack of parts. Synths such as the Prophet 5, Fairlight CMI, and Korg Mono/Poly relied on voltage controlled filter ICs — the SSM2044 — that you can’t buy new anymore. If you can source a used one, be prepared to pay $30. New old stock costs about $100.
Now, these chips are being remade. A new hardware revision for this voltage controlled filter has been taped out by the original hardware designer, and these chips are being produced in huge quantities. Instead of $100 for a new old stock chip, this chip will cost about $1.60 in 1000 unit quantities.
The list of synths and music boxes sporting an SSM2044 reads like a Who’s Who of classic electronic music machines. E-Mu Drumulators, Korg polyphonic synths, Crumars, and even a Doepfer module use this chip in the filter section. The new chip — the SSI2144 — supposedly provides the same classic tone but adds a few improvements such as improved pin layouts, an SSOP package, and more consistent operation from device to device.
This news follows the somewhat recent trend of chip fabs digging into classic analog designs of the 70s, realizing the chips are being sold for big bucks on eBay, and releasing it makes sense to spin up a new production line. Last year, the Curtis CEM3340 voltage controlled oscillator was rereleased, giving the Oberheim OB, Roland SH and Jupiter, and the Memory Moog a new lease on life. These chips aren’t only meant to repair broken, vintage equipment; there are a few builders out there who are making new devices with these rereleased classic synths.
Last weekend was the Vintage Computer Festival East in Wall, New Jersey. While this yearly gathering of nerds nerding out on old computers might be a bit too obscure for some, there are always amazing exhibits of actual historical importance. A few Enigma machines showed up, and the rarest Commodore goodies made an appearance. We saw the pre-history of Hackaday and ‘maker’ culture with Southwest Technical Products Corporation, and found out it was probably, possible to build a RepRap in the 80s. You can’t know where you’re going unless you know where you came from, and even though the old timers were a bit more grizzled than us the Vintage Computer Festival shows how little things have actually changed.
What was the coolest and weirdest stuff at VCF? What does the Silverball pinball museum look like? Check that out below.

Hackaday owes a lot to the hobbyist electronics magazines of yesteryear. Back in the day, Popular Electronics and Radio-Electronics would publish projects and articles about DIY electronics – more or less the same editorial purview we hold today. Some of these projects would become full-fledged products, and you need only look at the Altair for what can happen at this confluence of publishing and engineering.
One of the more popular companies to come out of these hobbyist trade magazines was SWTPC, or Southwest Technical Products Corporation. This was the company that brought one of the first microcomputers to the masses with the SWTPC 6800. This wasn’t just a homebrew microcomputer company – there were Nixie clocks, test gear, and stereo preamplifiers – all things that could easily find a place on the pages of Hackaday today.
This year at the Vintage Computer Festival East, [Michael Holley] brought out the test gear he’s been collecting for the past few decades. These are machines that wouldn’t be out of place on any DIY electronics blog today. This is by all accounts the pre-history of the maker movement.

At the end of World War II, the Germans ordered all Enigma cipher machines destroyed. Around the same time, Churchill ordered all Enigma cipher machines destroyed. Add a few decades, neglect the efforts of Polish codebreakers, and make a movie about Alan Turing and an offensively historically incorrect love interest, and you have a mystique around these rare, innovative cipher machine.
At the Vintage Computer Festival East, I was privy to what is probably the largest collection of Enigma machines on the planet. The exhibit comes from [Tom] and [Dan Perera] of Enigma Museum. Right now, they’re they only place where you can go out and simply buy a real, wartime Enigma machine. The price? Well, there is a pair of million-dollar Apple I boards at VCF. The Enigmas go for about a fifth of an Apple I.

This year at the Vintage Computer Festival, war was beginning. The organizers of the con pulled a coup this year, and instead of giving individual exhibitors a space dedicated to their wares, various factions in the war of the 8-bitters were encouraged to pool their resources and create the best exhibit for their particular brand of home computers. The battle raged between the Trash-80 camp and the Apple resistance. In the end, only one home computer exhibit would remain. Are you keeping up with Commodore? Because Commodore is keeping up with you. This exhibit from [Anthony Becker], [Chris Fala], [Todd George], and [Bill Winters] among others is the greatest collection of Commodore ever assembled in one place.
This year’s Commodore exhibit was a free for all of every piece of the hardware Commodore (or Zombie Commodore) has ever produced. Remember netbooks? Commodore made one. Remember when people carried dedicated devices to play MP3s? Commodore was there. Did you know you can spend $20,000 USD on a 30-year-old computer? That’s Commodore.

Today, if you want to teach kids the art of counting to one, you’re going to drag out a computer or an iPad. Install Scratch. Break out an Arduino, or something. This is high technology to solve the simple problem of teaching ANDs and ORs, counting to 0x0F, and very basic algorithms.
At the Vintage Computer Festival East this year, System Source, proprietors of a fantastic museum of not-quite-computing equipment brought out a few of their best exhibits. These include mechanical calculators, toys from the 60s, and analog computers that are today more at home in a CS departments’ storage closet than a classroom. It’s fantastic stuff, and shows exactly how much you can learn with some very cleverly designed mechanical hardware.
