I will be seriously impressed by anyone who can get this one. This was rescued from a discard pile at MIT back when I visited as a pre-frosh in 1992. I wasn’t too big on the campus tours–they were so boring and always showed you the stuff they wanted you to see anyways–so I went out on my own and nosed my way into every EE-related building, sticking my head into labs, offices and lectures unannounced. I eventually wound my way to the Media Lab and naturally I gravitated toward the machine room and let myself in, and found this in a pile of boards to be discarded. The guy there was friendly, told me what it was, and let me take it home and it’s been a prized posession since. It’s not a prototype board; from my understand this was used in a “production” machine. Back then it wasn’t so uncommon to see wire-wrap in a production machine! There’s still an old Symbolics machine hanging out at CSAIL somewhere, I think, that was wirewrapped.

Winner of Name that Ware Februray 2007!

April 4th, 2007

Thanks to everyone who played last month’s Name that Ware. There’s a certain satisfying sense of closure in discovering the origin of an old ware you’ve had in your closet for a long time. It’s even neater to know that I had something as classic as a board from a PDP-11 hanging above my desk when I was a kid, even if I didn’t know it at the time.

It’s a hard choice to pick one winner, so I’m going to pick two: Nicholas and Phil, congratulations! email me to claim your prize. The link to the bitsavers page in particular is really neat; I’m bookmarking that one. I’m glad that someone is going around collecting all the schematics and code that ran on these classic machines, and I’m even more glad that I haven’t heard of any lawsuits from copyright holders trying to milk the last dime out of some dead documents. I guess the sad part is that I don’t really see a bitsavers happening for any of today’s machines or chips. I wonder if in twenty years we’ll look back at these funny old Pentium chips and simply shrug our shoulders and go, oh well.

A Live DJ Set

March 24th, 2007

Last weekend, I did a live DJ set (along with Marc (DJ Warpt) and Caustik) at a birthday party for me and my friend Fry. I had the fortune of remembering to set up a laptop to record the gig, and Marc was nice enough to transcode the set and put it up on his site for people to download. It’s been a while since I had done a live set so I’m a little rusty, but I’m not too unhappy with how it came out all things considered. If you’re wondering what’s in it, it’s mostly progressive house and vocal trance, a little mash-up, a little breaks–and a recitation of the fibonacci sequence.

Here’s a direct link to my set.

It was fun to see the spread of techniques and technological proclivities represented by the line-up. There was me with my Technics turntables and Serato Scratch Live, Marc with this Pioneer CD mixers, and Caustik using a slick PC-based DJ tool called Ableton Live and a MIDI deck. We had fun after the party giving each others’ equipment a try. Also, thanks to Cathy for putting the whole event together! She put a lot into getting the venue (Fry’s house) set up and looking nice.

Scritch scritch–huh?

I was poking at the CIA World Fact Book, which is a fascinating resource in itself, and noticed this table of “current account balance” by country. It’s a big table, so I won’t quote it here, but to understand my puzzlement, take a look at the top ten names, and then look at the bottom ten names…and then notice the magnitude of each balance. One of these kids is not like the other…

Is this something to be concerned about? Warren Buffet seems to think so.

For contrast, try out this table of GDP by country. This is closer to what I expected for the top 10 and bottom 10.

On a possibly related note, I was trying to import some Korean DRAM today, and it was stopped in customs, where I discovered that the US is charging a 40%(!) tariff on DRAM chips imported from certain Korean manufacturers. I guess this partially explains why the Idaho-based Micron seems to dominate the inventory in distributors in the US, and how they can charge a 2-3x price markup over what I can get overseas. Then again, it’s somewhat comforting to know that some of my DRAM comes from the same state that my french fries and potato chips do.

I guess the question is, would customers of finished products like the chumby pay extra just because it contains US-made DRAM.

I’m guessing not.

Name that Ware February 2007!

February 28th, 2007

The ware for February, 2007 is shown below. Click on the picture for a much larger version.

I have had this ware since I was a wee lad, since I was probably just over a decade old, but to this day I don’t know what it does. I used to hang it over my Apple ][ in the basement where I would hack late into the night, writing assembly and BASIC code to control little hand-built robots and voice synthesizer cards. Clearly, the ware is from a DEC machine of some type, but I don’t know which one or what it does. I figured maybe this would be the right place to get answers to such mysteries from my youth, so here it is! Hopefully someone will be able to tell me what this relic did.
