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.
The Vintage Computer Festival East is going down right now, and I’m surrounded by the height of technology from the 1970s and 80s. Oddly enough, Hackaday frequently covers another technology from the 80s, although you wouldn’t think of it as such. 3D printing was invented in the late 1980s, and since patents are only around for 20 years, this means 3D printing first became popular back in the 2000’s.
In the 1970s, the first personal computers came out of garages. In the early 2000s, the first 3D printers came out of workshops and hackerspaces. These parallels pose an interesting question – is it possible to build a 1980s-era 3D printer controlled by a contemporary computer? That was the focus of a talk from [Ethan Dicks] of the Columbus Idea Foundry this weekend at the Vintage Computer Festival.
The VCF East is the largest gathering of retrocomputing aficionados on the east coast. It’s three days of talks, exhibits, a flea market, and a pow-wow of the greatest minds buried under obsolete technology. No VCF is complete without a few talks, and this year is shaping up to be great. Keynotes will include [Bjarne Stroustrup], designer / implementor / inventor of C++. Computer historian [Bill Degnan] will give a review of 40 years of ‘appliance computers’, and [Tom Perera], Ph.D. will be giving a talk on the Enigma machine.
The exhibits at VCF are always the star of the show, and this year is no different. Highlights include mechanical computers, the finest from Silicon Graphics, and a version of Unix published by Microsoft. The individual exhibits are always great; last year the world’s first digital camera made an appearance. If you’re in the area, this isn’t an event to miss. VCF is going down at InfoAge, a science center at the former Camp Evans — a military installation that is best described as, ‘DARPA before World War II’.
Hackaday is proud to once again sponsor VCF East. This has been going on for a couple of years now and our Art Director, [Joe Kim] has created some incredible art as part of the sponsorship. Click on the thumbnail of this year’s art to embiggen. The VCF West art from last year is a stunning take on the Macintosh and last year’s VCF East art reflected the retro hackathon we sponsored.
This is from the Daily Fail, but a working Apple I is going up on the auction block. It’s expected to bring in $317,693 USD. In other news, we’re going to be at the Vintage Computer Festival East at the end of the month. There is usually an Apple I there.
The most popular crowdfunding campaign of the month is Lego tape. It’s an adhesive-backed tape with studs on the top, allowing you to clip Lego pieces into place. How easy would this be to create at home? It’s really just a silicon mold and some 3M stickytape. Anyone up for a home casting challenge?
You guys know the Hackaday Overlords have a Design Lab, right? What’s a Design Lab? It’s a place filled with tools where we allow residents to come in for free, build stuff, give them training, and let them keep all their IP. It’s like a hardware accelerator, but focused on Open Source hardware. It is our gift to the community and we ask nothing in return. But that’s not important right now. We’re doing shots.
2017 will be the first year Maker Faire will have three flagship faires. New York is a given, as is the Bay Area. and A few weeks ago, Chicago grabbed the third flagship faire. If you’ve already bought tickets and scheduled your trip, terrible news: the Chicago Maker Faire has been postponed until late fall.
Flip clocks are cool. What’s a flip clock? The clock in Groundhog Day, or a bunch of flaps, gears, and a synchronous motor that displays the time. You know what’s not cool about flip clocks? They’re usually stuffed in horrible 70s plastic enclosures painted Harvest Gold or Avacado. [bentanme] found a flip clock and stuffed it in a glass jar. It’s kept in place by a few 3D printed parts that ingeniously keep the clock from moving around while still allowing you to see the gears. Neat.
[danjovic] sent in a link to this YouTube channel of a guy building stuff out of PVC sheets and CA glue. There’s a lot of stuff in here from a PVC tripod to instructions on how to get PVC sheets out of PVC pipe. Small warning: this is PVC, and it will kill you instantly, for reasons we can’t yet determine. Additionally, he’s heating PVC, which means cancer for your yet-unborn great-grandchildren. How it both kills you while still allowing you to breed is beyond our comprehension. That’s how bad PVC really is.
Last week, we had a Raspberry Pi Hack Chat with [Roger Thornton], the principal hardware engineer at Raspberry Pi. We talked about the hardware that goes into the Raspberry Pi (and the new Pi Zero W), and gave away a few Pi Zero Ws to a few people on hackaday.io that had great ideas for a project. One of the winners of a free Raspberry Pi Zero W was [arsenijs] for his Raspberry Pi Project. This is a really great project that uses a Raspberry Pi and Raspberry Pi accessories. It’s pushing the envelope of what a Pi can be, and a free Raspberry Pi Zero W couldn’t have gone to a more worthy project.
What are you doing the weekend of March 31st? We’re going to New Jersey for the Vintage Computer Festival East. This is one of the better cons we go to. Maybe this year we’ll organize a trip to the pinball museum in Asbury Park.
In the US, we don’t hear much about computing from beyond the Anglosphere. We’ve seen some home computer clones from behind the iron curtain, but getting any information about them is hard. If you find an old keyboard with a QWERTZ layout, or even a few Cyrillic characters, in the States, it’s a rarity. To date, the only French computer on Hackaday is an old Minitel dumb terminal. To help rectify this, [Jeremie Marsin], [Thierry Mazzoleni], and [Jean Paul Mari] from Quebec brought the best of the French computing revolution of the 1980s along to this year’s Vintage Computer Festival East
The American-designed French Victor
The evolution of the reigning champion of this exhibit begins with the Micronique Victor Lambda, a licensed copy of a purely American computer, the Interact Home Computer System. This computer featured a 2 MHz 8080A, 8 or 16 kB of RAM, and was quickly discontinued. The French company Micronique quickly bought the original designs and remarketed the computer in France.
In a few short years, Micronique took this design and turned it into the Hector. This machine featured a 5 MHz Z80, 48 kB of RAM, high resolution graphics (243×231 at four colors) and included BASIC and Forth interpreters.
The Victor and Hector were the best home computers at the time, but for every Commodore or Apple, you need a ZX Spectrum. France’s version of this tiny computer with a terrible keyboard was the Matra Alice 32, a computer with a 1 MHz 6803, 16kB of Ram, and a real 80×25 text mode. The Alice is heavily based on the American TRS-80 MC-10, with a SCART connector and an AZERTY keyboard.
The weirdest computer [Jeremie], [Thierry], and [Jean Paul] brought out? That would be the Excelvision EXL100. The 1980s, for better or worse, were the times of the Z80 and 6502. The EXL100 was running something completely different. This home computer used a TMS7020 CPU from Texas Instruments, a speech synthesizer, and a wireless keyboard. Very strange for the time and relatively inexpensive; in 1984 this computer cost only ₣3190, or about $550 USD.
[Jeremie], [Thierry], and [Jean Paul] had an exhibit that presented the best the Francosphere had to offer to the computing world in the 80s and 90s. We haven’t seen enough early computers from outside the US, so we’re happy to have met these guys at the 11th annual Vintage Computer Festival East.
There was a time in the late 80s and early 90s where the Amiga was the standard for computer graphics. Remember SeaQuest? That was an Amiga. The intro to Better Call Saul? That’s purposefully crappy, to look like it came out of an Amiga. When it comes to the Amiga and video, the first thing that comes to mind is the Video Toaster, hardware and software that turns an Amiga 2000 into a nonlinear video editing suite. Digital graphics, images, and video on the Amiga was so much more than the Video Toaster, and at this year’s Vintage Computer Festival East, [Bill] and [Anthony] demonstrated what else the Amiga could do.
