EdIII writes with this awesome snippet from Hack a Day: "'[phreakmonkey] got his hands on a great piece of old tech. It's a 1964 Livermore Data Systems Model A Acoustic Coupler Modem. He recieved it in 1989 and recently decided to see if it would actually work. It took some digging to find a proper D25 adapter and even then the original serial adapter wasn't working because the oscillator depends on the serial voltage. He dials in and connects at 300baud. Then logs into a remote system and fires up lynx to load Wikipedia. Lucky for [phreakmonkey] they managed to decide on a modulation standard in 1962. It's still amazing to see this machine working 45 years later.' Although impractical for surfing the Internet today, there is something truly cool about getting a 45-year old modem to work with modern technology. The question I have, is what is the oldest working piece of equipment fellow Slashdotters have out there? I'm afraid as far back as I can go is a Number Nine Imagine 128 Series 2 Graphics card on a server still in use at my house which only puts me at about 14 years."

As recently as a few months ago a friend was on the internet with his laptop (running linux) and it was still susceptible to this. After about an hour of fun I remotely patched his modem for him. Those were the days.

If you watched the video you'd know that this acoustic coupler doesn't support AT commands - or any other kinds of commands. it just converts bits it receives on the serial port into pulses in the tone it generates, and it converts pulses it receives into bits on the serial port.

I think a lot of things in those days were built without a really good understanding of engineering, so things were typically over-engineered. Things were built far stronger than they needed to be because people didn't have a good understanding of the strengths of the materials they were using or of the physics being employed in their designs. Likewise, without a lot of advanced chemical and metallurgical expertise, they weren't able to create materials specifically to meet the demands of the job like we can today.
The result is they had things that were much stronger, but took a lot longer and cost a lot more to make. Now, we have things that are designed specifically to try and hit the sweet spot between durability and cost, and that can be efficiently mass produced. As a result, our stuff doesn't last as long, but we can afford to buy a whole lot more stuff.

If anybody wants an old "clacky" keyboard, there really is a really cheap and easy way to get one-Go to your local mom&pop shop. We always have stuff like that around, because we are packrats and never throw anything working out. When I ran low on "claky" keyboards I just went to the other shop down the street and he let me rummage through his keyboard box. I got an old IBM and the Compaq I'm typing this on now for a whole $7.50 for the pair.
So go and visit your local mom&pop repair shop, it is like old PC junk heaven. Hell I even have some old S3 Virge cards sitting in the drawer here somewhere. Hey, you never know when they may come in handy! But any mom&pop repair shop that has been around for any length of time quickly becomes a "Sanford&Son" junk shop for anything tech related. We just don't have the heart to throw working gear out. Some come on down! It'll be an adventure! Don't suppose I can interest you in some S3 Virge and Matrox PCI cards?

For my own implementation of PSK31, I once ran it at a carrier of 62.5 hz. Sounded more like war drums than a digital mode over my subwoofer, but it still decoded OK.

Well as far as modem technology goes I've still got a classic 1200 baud Hayes modem; must be from the early 80s I would guess (perhaps older?); it was working fine when I stopped using it around 1993 or so (upgraded to 2400 baud FTW!!)* ... I'm sure it would still work if I plugged it in today but I'm not hunting down an RS-232 adapter to find out. If we want to talk audio gear I've got some much older items, including a pair of AR speakers from the 60s that still sound pretty damn good... Now get the hell off my lawn!

Amiga 2000 to surf the web (Score:4, Interesting)
I still have an Amiga 2000 standing around from 1989 with a 8 Mhz 68000 CPU and 7 MB RAM. Funny thing about it is that it can run the relatively modern AmigaOS 3.1, for which reasonably well working graphical web browsers exist. Occasionally I fire it for fun just to demonstrate that 80's hardware can show web pages in a semi decent way. Configure it to run on a 640x400 screen with 8 shades of grey and it still shows most of the modern web sites that have some sort of accessibility fall back. It can do tables and basic CSS, so in some cases the results are almost indistinguishable from what you see on a modern browser. Of course it is awfully slow and needs several seconds to render a medium sized PNG image.
It's particular cool to show it too kids that think you need GHz's and GB's to surf the web.
