sorry for the crappy cell phone pics

I'm trying to wire in a new connector, and I tried just shoving the wire in to the little slots, and that doesn't work.

Is there a special technique of a special tool you use for these?

It looks like an awful lot like a punchdown block. What application is this for?

i'm guessing its CAT5 from the colors

you need a special punch down tool, it looks like this:

^^,^ thank yous


This is in my apartment. I'm trying to rewire one of the phone jacks as an ethernet for my PS3.

Definitely a 66/110 punchdown block, then. You'll want a punchdown tool like the one shown above - they generally run less than $20.

I have this one and it's served me well.

sears has these clearance

^ The punchdown tool you mean?

meh, you can get by using a really really small screw driver if that's all you have. just be careful not to break anything

2/21/2009 6:40:19 PM

^ I think i've already broken something, but there are multiple empty blocks

2/21/2009 6:50:33 PM

you can't just wire shit however you want to

[Edited on February 21, 2009 at 7:05 PM. Reason : well, depending on what you want to do maybe you can. but yea, just shove shit in there]

[Edited on February 21, 2009 at 7:05 PM. Reason : or go buy a punch tool then return it]

The tool is cheap, and it's way, way easier than trying to do it with a screwdriver. Don't try doing it without one.

2/21/2009 10:43:59 PM

yeah, you'll either end up stabbing yourself in the hand and/or destroy the punchdown block

2/21/2009 10:47:16 PM

I went to Sears and didn't see any. I think i'll try RadioShack tomorrow.

And i'm not wiring things randomly either...

But, if anyone can confirm, on a typical cat 5e ethernet cable, only the first 3 and the 6th wires are actually used, correct?

^^ for 10/100 you only use two pairs.

If you're going to do gig, you need all 4 pairs.

2/22/2009 11:25:24 AM

lulz BobbyDigital beat me to it, gigabit uses all 8 conductors in 4 LVDS pairs

i'm going to hijack for a moment and ask about this connector.

It's from an old ATI video card I got from a computer laying around at my dad's house. I believe it's an ATI All-in-Wonder Radeon tv tuner, but I can't find a picture of a card like this online.



what the hell is the square connector? is that some special version of DVI?
I'm trying to install the card into an old PC (like.... AMD XP 2100+ old). Problem is, whenever I plug the card into the AGP slot, the onboard VGA-out stops working. And since I don't have whatever-the-fuck cable is supposed to work with that ATI card, i lose all video out. And I can't install the ATI drivers ahead of time (in case that would help with the VGA video out) b/c they won't install when the card is not plugged in....

2/22/2009 10:50:42 PM

it is a proprietary cable that had 2 hd-15 in this dongle type set up

2/22/2009 10:55:46 PM

yeah, actually i just had a vision a few minutes ago. I now recall having a dongle with several connectors, including I think a DVI, VGA, and component cables.

damn..... no way I still have that thing around

ebay is your friend btw

here's another random connector question -
I've run across a couple old HDDs, from the mid-90s i think, with 50-pin SCSI connectors. I have a SCSI cable, but of course, no computer to connect the drives to.

is there a SCSI to IDE or USB adaptor? I've found a few online but they are hella expensive. it looks like the conversion can't be done passively.
Anyone have any ideas of how to get the data off those drives? Or anyone have some old working PCs hanging around I could use some time on?

2/28/2009 1:24:35 PM

one of the oldest servers at work uses those type drives. if you can't find anyone else let me know and i'll see what i can do to help.

2/28/2009 1:26:20 PM

yeah, it's a completely different bus, can't be done passively

look on the drive - is it scsi-3? u160? u320?

i may have a powervault or two lying around if you need to get the data off of them

you can usually find a scsi enclosure and a scsi controller card on ebay for a few hundred bucks if you really want to get them working

2/28/2009 2:42:00 PM

i have no idea what specific kind of SCSI they are. I pulled them out of an old Power Computing Mac clone from the 90s. I don't even know what is on them, except I suspect maybe some old files and papers and stuff from high school, which would be cool to recover. I have 2 - an IBM that is 2GB and a Seagate that I can't tell how big it is. I'm not interested in spending more than 10's of $ to buy anything, since I don't even know what's on them, but just for curiosity, it would be cool to borrow some time on an server or powervault to see if I can transfer something.

here's some bad pictures of them, if anyone can gleam anymore info from them

2/28/2009 10:09:20 PM

are there no jumpers on it?

2/28/2009 11:13:04 PM

oh, yeah - on the Seagate one the jumpers are on the opposite side as the SCSI connector. It's set to the 2 far-right pins (last pin on top and bottom row). It's in the "ADDR 1" column, according to this diagram on the drive



The only jumpers I see on the IBM drive are underneath on the exposed logic board. It has 12 columns, and column 7 is tied with a jumper, labeled as "disable unit attn"

holy shit

those are ultra-3 fast-20, you need something with an IDC50 connector.

i don't have anything that will take that, sorry

i was thinking it was one of the newer ones with an SCA:

LOOKS LIKE I'LL HAVE TO TAKE UP THE HOMO'S SLACK HERE

US HOMOS ALWAYS FAIL AT ARCHAIC SCSI CONNECTORS

3/1/2009 9:17:41 AM

yeah, i was actually surprised they were SCSI. I looked at them an thought maybe there was an older version of PATA/IDE, but I found an article on the history of SCSI that showed these.

I do have a 50-pin ribbon cable to go along with them, but no mobo to plug it into

damn son

get some new shit
