Removing angle connector from IIsi Nubus adapter

[beachycove]

I want (I was going to say "need," but that wouldn't be honest) to remove the 90º PDS angle bit from a IIsi nubus adapter, in order to use it in a SE/30 (in order to have two pds cards). This means de-soldering a lengthy and numerous series of wires from the adapter card.

How should I best go about this, and how do I do it without melting the plastics at the pds connector itself?

Are you going to try to use the NuBus slot in your SE/30? This may prove to be problematic, because the "NuBus" signal present on the IIsi's PDS is conspicuously missing on the SE/30's PDS.

If you just need a PDS PassThru, the NuBus adapter won't work anyway, it only has PDS in and the smaller NuBus connector out.

Check out a less than elegant, but remarkably effective, EuroDIN Connector De-Construction technique I developed.

I practiced on the inexpensive (available from macmetex's eBay store) SuperMac RA PDS Adapter card before working on the inexpensive (also available from macmetex's eBay store) Radius Color Pivot II/IIsi Card which makes a fine PassThru Video Card (w/addressing jumpers available on board) for my IIsi, but it ought to work in your SE/30 as well.

Dunno, give us some more details. :?:

Trash, interesting technique for removing the connector. I thought about taking an end-mill to one and going over it really slow, but now I don't have access to one. Did it seem like you weren't stressing the pins and solder joints?

Another idea I have to remove the socket is to cut it into smaller lengths with a saw and then heat a smaller group of pins and hopefully get the smaller block out in time before pins cool-off.

Someone posted somewhere to use a heat gun and cover all the components with modeling clay to insulate them from heat. You could put a couple layers of aluminum foil over the clay to insulate it even more. This is the method I am thinking of trying first to remove the PDS pass-through connector from a Asante ethernet board.

Breaking it up is certainly a simple method — but it surely doesn't work without also desoldering, does it?

What I was thinking of doing was using the 90º angle of the disassembled IIsi card, then connecting another IIsi PDS 'euro-din' connector at the 'wire' end, then plugging in another pds card. The purpose of this is to pop a (repaired) SE/30 MacCon ethernet card with PDS pass-through connector into my SE/30, connect the 90º piece, and finally stack an SE/30 video card on top of it, so I could run a two page Radius display and have ethernet in an SE/30. It is something I have wanted to do for a while. I have only just sourced the components to repair the MacCon card, but am trying to see how best to make the necessary connections between it and the other hardware I want to install.

If there is a better way of making the MacCon-to-Radius card connection, I'd love to know about it. I asked about this a while ago, but did not get especially far....

The trouble with the MacCon pds pass-through is that it was made to be just the right height for the IIsi, but by the same token, it is probably in the worst possible place in an SE/30. The floppy is in the way, and the metal frame, so that nothing can be plugged into the thing in an SE/30.

Yes, desoldering as COMPLETELY as possible was done before deconstruction of the *&*^&&^^$%#$#@ connector, which would not let go of the PCB. Very little tension was applied to the few (15-20) pins that had resisted the desoldering process by hanging on to the edge of the thru-hole. I didn't pull the connector out at all, I crushed the blasted thing, munching at it sideways from on end to the other.

Check out the end of the IIsiColorPivotII_PDS_Card_HackProject™ topic for pics of a great way to stack SE/30/IIsi cards in the SE/30 or line them up across the underside of the IIsi's MoBo.

I'll be modifying the IIsiColorPivotII card or the SuperMac PDS adapter to mount to the bottom of the PDS slot in my IIsi. Everything depends upon ROM testing at this point, the SE/30 apparently has five available addresses for expansion, while the IIsi ROM only supports three slots.. The other test will be to determine if I can use the NuBus adapter with at least the two PDS Cards which the IIsi ROM should support along with a NuBus Card.

I used a smoothing iron to remove EISA 32 bit slots from a PC mobo.

I wanted the slots for my Amiga2000 back then and soldered them in.

Now that's interesting. Do you mean an antique one place on a stove/ burner and heated up fit to bust, or a normal, bog-standard, iron-yer-clothes electric iron? Can the latter really get hot enough to melt ordinary lead solder?

 

[beachycove]

That led to some googling. And would you lookie here!

WOOHOO!!!!!!!!!!! [] ]'> Gotta love it!

It doesn't matter, either way I'll have to work at not becoming a YouTubeBoob!

ChipQuick (sp?) is a magic goo that softens the solder. Free samples and directions for use at their site. The other thing you need is either a solder sucker (manual bulb, spring loaded, whatever) or/and some desoldering braid - fine, woven copper wire that soaks up the solder. Work on alternating pins some distance apart, so the area you've just finished has time to cool.

Just to confirm - yes I did it with a standard electric iron like shown in the video, actually my fingers became hot too

Soft solder flux or a solder sucker may help, but I simply pulled out the slots.

I did not mind the solder on the pins, because I would need some anyway on my partial empty A2000 board.

Cotton setting? :?: Cool beans!

Just for the record: we're talking about removing the connector from a PDS Card, not the NuBus Card, correct . . .

. . . or are you trying to get a NuBus Card stacked into an SE/30 along with a PDS Card? :?:

 

[beachycove]

PDS

 

[Trash80toHP_Mini]

Do you want me to change the topic to . . . a PDS Card Connector as opposed to a NuBus Card Connector?

As I said, the IIsi NuBus adapter card is of no use other than as a NuBus Chipset/bridge/Right Angle Adapter for the IIsi . . . for now! }

It has to be a PDS Card to work, like the inexpensive ones I mentioned above.

Tell us which of the Gamba PDS hacks you're trying to do or sketch, scan & post the notion you're playing with along with the scoop on all the cards you'd like to use to overburden your SE/30's PSU.

Another idea I have to remove the socket is to cut it into smaller lengths with a saw and then heat a smaller group of pins and hopefully get the smaller block out in time before pins cool-off.

Been there, gave up on that. With a lot of hand work it's possible, but tedious to do it that way. I tried it with a blade that was way too big on my Bandsaw with mixed results. With the right blade and an incrementally stopped jig/sliding table it'd probably work, but ChipQuick and an iron seem like the ticket for my next attempt at pulling a usable EuroDIN Connector of a donor card . . . AFTER I run out of the parts trag sold me. [] ]'>

ChipQuick, the low temp solder alloy, got me nowhere. The stuff started flowing into the pins of the socket, and probably created shorts, so now I need to definitely remove the Euro-Din connector if I ever want to use the board again.

Which Friggin' Board? PDS or NuBus Adapter and WHY????

I hope you're practicing on one of the inexpensive substitutes I suggested and NOT borking something as valuable as a IIsi NuBus Adapter!

WT*H*e*Doubletoothpics is going on with these hacks!?! :O

What I want is effectively Gamba's SE/30egs, and it is a IIsi PDS to Nubus adapter that I had thought it possible to cannibalize, but I shall investigate the other options. I am some weeks from doing anything yet.

I think I have three of those IIsi cards. But on Gamba, the thing I really need and that would make all of this straightforward is just the angle adapter that he sold to make dual PDS setups in the machine trivial. I don't suppose anyone kept a few spares?
