Connector search

[+DarkLord]

Hi gang. I need help finding a connector.

 

Specifically, 2.54mm pitch, single inline sockets, 10 count and

30 count.

 

I've ordered from 3 different sites so far, Jameco, Global, and

Uni something or the other...

 

All 3 parts from these places match perfectly as far as the spacing

between pins, the problem is, the pins themselves are just too small

to fit the header. You can push them in, but they are so loose they

fall right back out.

 

Here is an example of what I ordered:

 

http://www.jameco.com/webapp/wcs/stores/servlet/ProductDisplay?langId=-1&productId=78642&catalogId=10001&freeText=78642&app.products.maxperpage=15&storeId=10001&refine=1&history=lnlzkog0%7CsubCategoryName%7EInterconnects%5Ecategory%7E30%5EcategoryName%7Ecategory_root%5EprodPage%7E15%5Epage%7ESEARCH%252BNAV&ddkey=http:StoreCatalogDrillDownView

 

It looks like, from the data sheet, if I'm reading it correctly, that the pin

size is 0.48, and that's too small.

 

What I'm trying to do is raise the internal power supply board on a

STacy up just a bit - so I need 2 of these, one 10 count and one 30

count, to go between the pins from the motherboard, and the socket

on the underside of the internal power supply board. The sockets on

the underside of the internal power supply board are labeled

 

JAE 10TS and 30TS

 

If it helps, this is the same setup on a Mega STe.

 

Thanks.

perhaps something like this:

Right, that *looks* like it would work, doesn't it? I'd actually looked at that item from Jameco

before. The question is, how big are the pins themselves? Unfortunately, this item doesn't have

a data sheet.

 

They certainly are cheap. I could order just to try them out.

 

Thanks for the reply, Poobah.

Okay, I ordered a handful of these - just came in today.

 

The femaled (bottom) end does match up with the pins coming off the headers

on the motherboard itself. Unfortunately, the male end pins are (again) just

too small to fit into the female end header/riser on the bottom of the internal

power supply board itself. They are so loose that you can put them in, turn it

over and they just fall right out.

 

Anyone know of this same item with male pins about twice the size? Thanks.

might be time to solder a different header on the power supply itself

I had actually considered that as well - but only as a last resort.

To be honest, I just don't have great soldering skills. Poor eyesight

as I get older doesn't help any either.

 

I was thinking that I might try to just "glaze" the pins on the Jameco

socket and see if I could make a solid connection with it then. Guess

it wouldn't hurt to try if I can't find anything that exactly matches.

 

Whatcha think?

I'll have to take a look at my Stacy and see what a good attack route might be. It really does sound like changing the connector on the power supply might be the path of least resistance.

Another update on this part of my STacy update/restoration project.

 

After much experimentation, like many others, I've also come to the conclusion

that I can't put a T25 accelerator in, and keep the internal P/S board where it

is. I've tried every combination of risers, sockets, etc, that I can find and I just

can't get it to work.

 

Therefore, I'm following the lead of Marc-Antón Kehr, and his Super STacy here:

 

http://atari.st-katharina-apotheke.de/home.php?lang=en&headline=SuperStacy&texte=S_STacy

 

Here is my STacy's internal P/S board, flipped over, with the extension cable I made attached:

 

 

Now here is the extension cable attached to the motherboard headers:

 

 

And here it is, zoomed out a bit so you can see them connected:

 

 

Now, we've got to "adjust" the RF shield to make room for where the internal P/S is going.

Here is the original shield:

 

 

Here is the part that is coming off, what's left, and how it originally set in the STacy:

 

 

 

 

(continued in next message)

[+DarkLord]

Now here is the motherboard, with the internal P/S board setting approximately where it

will be when reassembled:

 

 

Finally, here it is with the modified RF shielding in place. so you can

get a good idea of how the new layout will be. The internal P/S board

is now sitting under where the original battery compartment was. I've

got to remove that from the upper lid, to make room for the internal

P/S board vertically. Nothing lost there really, the compartment was

never used except in the very first production models, because Atari

realised that only about 15 minutes of operating time was all you could

get. I'll post pictures of that mod. when I get to it. And yes, that is my

left foot in the bottom corner - no extra charge.

[+DarkLord]

Okay, here is what the STacy case looks like, before and after battery

compartment removal. I'm also showing the piece I'm planning on flooring

that section with, so that I'll still have a small storage compartment.

Here in these next 2 pics you can see the height difference:

Here's a couple more pics - showing my STacy with the battery compartment

re-floored now, and matching gray color. Now I have a functional storage

compartment again.
