Hi there,
within the package of System7-floppies, that I won in an auction, the seller added 2 boards and I don't know, what are they meant for (no description or labels included).
Anyone here who could give me some hints?
I also got a Macintosh Classic at a present (thatswhy I went for the System7 disks). May I use one of these cards for the Macintosh?
Thanks for your help!

It seems to be some model of Farallon Phonenet NuBus card. I think those two boards are one complete unit. Does the cable coming off of Card B fit in Card A?

Thanks for your help! And yes, you're right, the cable attached to Card-B does fit into the socket on Card-A.
But it seems to be not a NuBus card. The NuBus card has 32 pins in 3 rows, my card has 40pins in 3 rows.
I've checked a lot of pictures about vintage expansion card an socket, but couldn't find any with so many pins so far.
And there's one pin missing, don't know if accidently broken off or intentionally ...
Well, I don't want to recycle the card, cause there might be someone in need for exactly this thing for his vintage machine ... or maybe only partly.

Edit:
Found out more about the 40x3 pin connector: there's e.g. a Daystar DualPort IIsi extension-card, that fits into the PDS-socket (ProcessorDirectSlot), that sports a socket for a cache-card and another for that kind of 40x3 pin male plugs for another extension-card, like the above CardB.
So my cards may be mother and daughter card for networking? and being connected to a Daystar DualPort IIsi?

It's a PDS card. It looks to be for the SE/30. Not sure if any other models share the same slot. As the connector is labeled AMP 535022-1 in the picture. That appears to go with the SE/30.

That Daystar board looks to just split the IIsi PDS into two slots. As I recall the IIsi used a riser board for the PDS. That Daystar likely just split it to encourage people to use their card without sacrificing the only expansion slot. It's probably unrelated to your card.

From that Technical Note: "The PDS in the SE/30 is a 120-pin, 32-bit PDS..."
"Connectors for the PDS may be obtained from AMP (part number 535022-1)."


Ymmd! ? Many thanks again!!!

So that network-card coincidentally is exactly, what I'm looking for, since last month I went for an SE/30 as my personal birthday-present and together with the Macintosh Classic, that was gifted to me last automn, I'd like to build up a little 68k network.
Got a bunch of PhoneNet-adapters and a 50 bucks Wallstreet/PDQ in the meantime too.
The PDQ may connect via AppleTalk and Ethernet simultaneously and is the missing link to the rest of my network:
68kMac/os7/AppleTalk <> [PhoneNET] <> PDQ/os9 <> [Ethernet[ <> PPC/OSX

With that cord-combo the SE/30 would be able to connect via Ethernet too.
I wonder, if the missing pin is a mission critical damage or just left out by intention and if it would be accessible to repair ...?

There were various versions of your "Board A", some with an RJ45 twisted pair ethernet socket. However, you may be able to get a RJ45 10Base-T media converter to fit the 15pin D-sub AUI socket.

Hu, those "RJ45 10Base-T media converters" seem to be pretty expensive ... Given the fact, that I even don't know, if that card-combo is working at all and if that missing pin of the PDS-plug is a an essential defect, it's probably not worth the effort, to spend more time on this subject.
Since that card came to me as a donation I better hand it over to someone, who's exactly looking for such a part and I'm gonna keep it stored for the day to come ...

Nevertheless folks, thank you very much for your kind help!

Edit:
Found a "CentreCom AT-210TS Twisted Pair Transceiver ID1466" for 20 bucks and I'm back again in the ring for the second round.

Since you have a Macintosh Classic. I don't think those cards will work. As far as I can tell the regular SE was the only 68000 Macintosh to use a PDS slot. Which isn't the same as the SE/30 which had a 68030 PDS slot. Which also varies slightly from other 68030 PDS Slots although apparently cards may work with slight modifications between the IIsi and SE/30. Enabling the SE/30 to use a Daystar cache card and another PDS card via Daystar's PDS splitter meant for the IIsi. There seems to be more uniformity in the 68040 and first gen Power Macintosh PDS.

The only Classic models I could find with a PDS are the Color Classic and Color Classic II. Which used an LC PDS slot.

Oh, since the beginng of last month I also got an SE/30 in addition to the Classic, because I wanted/want to create a little 68k-Macintosh LocalTalk-network. I was already successful to establish a LocalTalk/AppleTalk connections between two Macs using a DB9 8-pin-printer-cable, after I found a 50€ Wallstreet/PDQ and I was really surprised, that the Wallstreet/PDQ is able to handle LocalTalk/AppleTalk connections and Ethernet-TCP/IP connections side-by-side to be the missing-link between the 68k-Macs and my PowerPC.
And now there are also 5 PhoneNet-adapters to connect everything simultaneously: the Macintoshs, the Wallstreet, a printer an maybe an old 68k-PowerBook, that previously need repair of the display bezel (that had been another occasion for 20€ a year ago).
At the end of last year I was also lucky to find system7 floppies (in the original box) for just 20 €, because I wanted to to upgrade the Classic to system7. And in that box coincidentally there were these two boards and I had no idea, what to do with them.
Then, at the end of the summer-holidays (I guess the shutdown caused me having quirky thoughts) there was that occasion of an SE/30 I could not resist ...
Maybe it ought to be an SE/30 because of having some more tweaking options in mind, I don't know - but the exsistence of the misterious two boards had been definitely not in my mind anymore, especially because thinking of Ethernet for the SE/30 made me always think of / look for something with an RJ45-connector. And I didn't even knew about the kind of (PDS-) extension-slot the SE/30 does offer.

So finding out, that the misterious board-combo possibly might be an ethernet-extension-card & daughter-card for the 32-bit PDS 120-pin socket of an SE/30 is really kind of crazy.

I didn't have that Daystar PDS-Spitter-Card in mind for the SE/30 - it was just the first thing that I found to sport that 120-pin socket, into that one of my two misterios cards could fit.
I dunno, if I may ever put this card into the SE/30 - especially since I don't know anything about brand and specs yet. Don't want to fry anything within the SE/30.

It's a real fun, to find out all these things with your help, guys!
Cheers and many thanks!
Bob

One note - both the SE/30 and the IIsi used the same PDS slot - although with the ribbon cable going between them, this one is almost certainly meant for an SE/30 (IIsi-oriented cards tended to be "solid" cards, no ribbon cable between pieces.)

And yes, that is definitely an Ethernet card. the use of DA-15 for Ethernet was common before the "RJ-45" jack became standard. The BNC port is for "10-Base-2 Thinnet" connections, the DA-15 is for an "AUI" breakout box. They are industry-standard, and you can find an "AUI to RJ-45" easily enough, I see them as cheap as $30 shipped on eBay.

Ah, thanks, great help!
I went for a CentroCOM 210TS Transceiver. Hope that was a good idea.
So the only open question is, if that missing pin of my NuBus-Card does matter and if it might become fixed by a soldering job ... (don't even know, if that card is going to work at all).

If I'm correct, that is Pin 33 on Row A, which ends up being Address bit 10 (Gong by the IIsi Technote)


Removing the existing connector is not something I would do without specialized equipment.

Not sure what your options might be, other than soldering a long jumper wire from under the motherboard to the PDS card. That would sadly make 'quick' removal difficult.

What is printed on the white label on the card ?

Don't know about in which direction rows are named, but it's Pin 33 on the upper row (red circle).
It's just missing. I don't know, if it had been broken off accidentally or if it was left out on purpose.

Sorry, I didn't get this suggestion about "removing the existing connector". The Pin 33 is missing. I thought that I maybe have to solder in a replacement pin. Actually I don't dare or want to alter anything within the SE/30, which is in focus, when it comes to avoiding any damage.
But since I do not have any clue about the origin of this board at all, I mean manufacturer etc., I think that it will all comes to the question of try and error.
Might that damage the mainboard of the SE/30?

You mean this one? Here's another picture ...

SSI seems to crop up here and there with LC PDS cards. Difficult to find info.

SSI NB128 top.jpg


I suspect these are a knock-off of somebody else's board. You may be lucky that it works with Apple's own drivers from NSI ZM-1.5.1 (for system 7):


That is, if 'Address 10' isn't important, but I fear it certainly is.

EDIT: Components appear to be VERY similar to the Farallon SI & SE-30 PDS Ethernet cards. Both your card and this Farallon use a Nat-Semi DP83901 and a couple of GAL ICs. Asante used a similar design too.

I don't know how you'd go about replacing just ONE pin on that 41612 series connector with 3 rows and Right-Angled too. :oops:

Thank you so much putting this effort into my question. Seems, that I have to open the SE/30 and just try ...
Well, this will be something for spare (& relaxed) time during chrismas-holidays.
Currently I'm busy to download the essential stuff from the Garden and other valuable sources using the Wallstreet/PDQ (with Ethernet for web-access & LocalTalk/PhoneNet-connectivity) and move that stuff via AppleTalk/PhoneNet to the Macintoshs in order to get sets of floppies ready for service.
Pretty time consuming indeed. I really forgot those times!
(So after this weekend my daily driver early-2008 MBP feels like running with supersonic speed ... :))
