There's A Little Geek In Ya

If you know what this is and where you would find it - and I don't mean the quarter, smarty pants!

Looks like a wee pat of butter. Ha!

Just the right size that if it were on George's lip, you could say "Let me get that for you" and all would be unicorns and sparkly bits.

It's a "DIP Jumper". Usually found on motherboards to set various things, on the connector-end of optical and hard-disks to set Master/Slave/Cable Select, and also used in many other applications where a regular switch would be too expensive.

Ding! We have a winnah!

Dunno what yer prize is, drjim, but with hope'n'change all is possible!

Revel in your Geekness!

Hell, I got a whole mess of 'em in my electronics box -- that's where I find 'em -- well, if'n I need one where it ain't been provided.

Now true geekdom would be setting the baud rate, etc., on a DLV11-J 4-port asynchronous serial board, using wire-wrap. Been there, done that.

I'll be drjim remembers dip switches too. And no, that's not when a Congresscritter changes parties.

I gotta admit I never messed with those old boards - when we finally got dialup out here it was 28.8 and I used winmodems as a rule. One could buy plug n play switches and routers (ten mbps). I ran into some of that when I started playing with some "old" stuff for fun.

But you'd be surprised where dip switches are found sometimes. When truck speedos and tachs went digital electronic from mechanical - dip switches on the back of the instrument calibrated the reading to allow for different gearings and tire sizes. Twenty five years ago and I still about needed a magnifying glass with my paperclip to set the damn things!

I still have equipment using dipswitches. My test equipment that has HP-IB uses them to set the buss address, and up until recently, when everything went "Menu Driven" a lot of Ham Radio gear used them to set various functions up.
I've worked with wire-wrap, but never to set options. I still have my "wrappers" and "UNwrappers" in the tool box!

I use a Magna-Visor now for any close-up work. It was getting bad enough needing three hands for a task, without needing to fourth to hold the magnifying glass.

I remember the HP-IB. I remember when HP was using it on their PC products to hook up printers. Talk about vendor lock-in. Fortunately for me, I was dealing with real instrumentation on a data acquisition project. That was fun.
