Name that Ware, October 2012

October 30th, 2012

The Ware for October 2012 is shown below.

I’ll set aside the collection of stumper retro-wares from my childhood basement for a bit and give you this modern ware to ponder. This one should be guessable, especially since I left all the telltale connectors in the photo.

Sorry about the infrequent posts this past couple of months, but I’ve been spending a good chunk of my time as an intern at a local infectious disease research lab. I’ve been hacking the E. coli chromosome, swapping out genes and observing its impact on various regulatory pathways. It’s been very interesting, and has really helped calibrate my intuition on many aspects of biology that I’ve read about, but until now had not reduced to practice. I did a genomic DNA extraction protocol the other day and it was pretty magical seeing DNA precipitate out of solution into wispy white strands (the E. coli chromosome is about 5 million base pairs in size, and these huge molecules quickly glob together into strands visible with the naked eye). It’s also been fun writing simple bioinformatic analysis tools to help sort through various genetic motifs. DNA is way more structured than I had previously thought — feels almost as structured as raw binary machine code — and short snippets of DNA (a few hundred bits worth) can implement proteins with surprisingly sophisticated functions.

So many things to learn…!

Winner, Name that Ware September 2012

October 30th, 2012

Yet another stumper from my collection of random old boards! There was no definitive identification of the boards or the system from which they came, but yes, they were made by Intertech. However, I’m not sure it’s the same Intertech as what comes up in Internet searches today. I’ll pick Mike this week as the winner. Congrats, email me to claim your prize!

The ware for September 2012 is shown below.

Hopefully this will be a bit easier of a retro-ware than the previous month’s! I’ve included photos of all three circuit boards that I have from the ware. Again, this is one for which I have no idea what it is from, but have been curious about since childhood.

Winner, Name that Ware August 2012

September 24th, 2012

Picking a winner for August 2012 is a tough one. Usually, there are multiple correct answers, with varying levels of detail. In this case, after doing a bit of research, I can’t really declare anyone a definitive winner, a problem in large part caused by the fact that I don’t know which ware this is from. For sure, the boards look similar in size and form factor to those found in the IBM 5100 series, but none of them are an exact match. However, I imagine IBM re-used the technology and form factor across multiple products at the time, so form factor alone cannot be used as a determinant for positive identification.

As a result, I’m going to award the winner’s prize to Brian, for sharing a large amount of interesting research with me on how the boards were manufactured (the excerpts from the IBM journal were a particularly good read). Congrats, email me for your prize!

As for the question about why the regular grid of holes — I found Tracy Hall’s comment about the use of an automated point-to-point wiring system to be compelling. However, after reviewing the IBM report, I was pretty convinced that these PCBs are made using multiple layers of etched copper. Thus, my guess is that the regular array of holes is due to one or a combination of the following: (1) CAD technology was not advanced enough back then to allow for the placement of arbitrarily located holes, particularly on large designs; on a low memory system (tens to hundreds of KiB) with no floating point support, it would be much easier to track hole and wire locations snapped to 0.1″ centers only, as opposed to storing a large number of coordinates to a high numeric precision. (2) It may have been more expensive to build a CNC drill versus just slaving together dozens of drills on a single rigid mechanical frame that was very precisely calibrated to make only 0.1″ steps. In other words, the cost of automation may have been great enough that it didn’t justify the savings in drilling time even if it meant potentially drilling thousands of extra, unused holes. The IBM article didn’t explicitly state why the boards were drilled in such a regular pattern, but it did make reference to slaving together dozens of drill heads to reduce drilling time. (3) As a matter of design discipline, it could have reduced errors and saved design time to force all holes to a 0.1″ design rule, versus taping out a PCB and finding that it can’t be manufactured because some ICs were accidentally placed a tiny bit too close in the artwork — or that holes on one layer didn’t line up with holes on another layer due to human error. The IBM boards had an unusually high density and layer count compared to other PCBs of the time.

EFF Pioneer Award

September 21st, 2012

I just had a legendary drop!

[tooltip content=”test” type=”wow”][EFF Pioneer Award][/tooltip]

I’m incredibly humbled and honored to receive a Pioneer Award from the Electronic Frontier Foundation. Thanks to everyone who nominated me for this amazing award. The recognition motivates me to work harder!

Over a decade ago when I first set out reverse engineering the Xbox, I didn’t set out to be on the electronic frontier. In fact, it was business as usual for me, trodding the same ground I had walked since I was a child: the frontier came to me. The passage of the DMCA in 1998 redrew the borders of the frontier, and I became a pioneer without ever having to journey from the doorstep of my log cabin.

You could say I have a very traditional notion of ownership. If I buy something, I find it odd to think that I don’t own it. However, in the world of software, that’s the standard: you cannot own the expressive results of another’s thoughts; you can merely license a copy of it. This has lead to a number of ownership paradoxes. For example, a few years ago, you could license a copy of a video game called Diablo II, and the license was such that decades from now, you could legally enjoy a moment of nostalgia while you played it on an old computer. Today, you can license a copy of its sequel, Diablo III, but it relies upon a cloud service to authenticate the copy. The owner has the right to terminate the authentication service and in doing so you agree to stop playing. Decades from now, you may still have the computer; you may still have a copy of the software; but you no longer have the legal right to play, as you gave it away in a click-through agreement.

I like hardware because it’s relatively free of paradoxes like this. There is a notion that when I buy a book, it’s mine to do with what I want. I can give it to a friend, sell it in a second-hand shop; I can tear pages out, scribble on it, use it as a doorstop or a bug-smashing instrument. I can even photocopy pages for my personal use. Since I was a child, I had applied this intuitive definition of ownership to hardware. I’ve always felt empowered to take apart hardware and rip-mix-and-sometimes-burn, much to my parent’s chagrin. Hardware to me is like a book: in fact, much of the technology used to make hardware relies on similar lithographic and printing processes. A PCB isn’t a “Printed Circuit Board” for nothing. You can open and read hardware like a book; to me a schematic and a circuit board or IC layout are expressing the same idea, just translated in different languages.

And so, when I first punctured the warranty seal on the Xbox with my screwdriver, I had no idea I was about to embark on a journey to become a pioneer. But as they say, ‘you can tell the pioneers — they have the arrows coming out of their back’. But really, all I’ve done since then is just stand my ground and defend my little log cabin, built out of simple notions that are as old as the first trade of eggs for grain.

I believe you have the right to tinker and take things apart, which is an essential prerequisite to owning something; and I believe that ideas are most powerful when they are set free and shared openly. While the lines that define the electronic frontier are constantly changing, we need not be victims of circumstance: take a stand, and be a pioneer.

Thanks to everyone who supported me and gave me the courage to earn this award — my parents, my partner, my teachers and advisors, particularly Tom Knight and Hal Abelson; and my friends and my colleagues who stood by me even in my darkest times.
