IIsi strange thing in the back

Author	Topic
raWr Junior Member Tuvalu 491 Posts	Posted - 16 Mar 2002 : 12:28:03 seems to be some kind of graphics card. I assume it's located in the Nubus slot. Haven't opened it up. The card seems to have a 9-pin male connector on the end of the card. Any clue? Fleet Covert Ops Macs liberated: 4-5
maclover5 LC Doctor/Hot Rodder Australia 5830 Posts	Posted - 16 Mar 2002 : 13:47:57 Thats an AUI networking card. There were a lot of IIsis that shipped with this strange beast, although today, noone uses AUI, as it has been replaced by RJ-45 long ago. If there's an RJ-45 port there, then you can just plug it into a network, although if there's no RJ-45 and you want to add one, just take it out, (its a NuBus card), and stick another board in there. -------------------------- Pizzabox LCs RULE!!!!!!!

AnubisTTP Junior Member USA 308 Posts	Posted - 16 Mar 2002 : 16:53:30 A lot of Cisco routers and switches still come with AUI ports on them, I think they are are for trunking or something similar. There is a dongle you can get to turn AUI into RJ45, you can most likely buy 50 of them off of Ebay for 3 bucks (or at least a lot cheaper than a Nubus card).

That shipped with them? I wouldn't think Apple would bundle things like that back in the day... I liberated a IIsi which had one of those cards, by the way (third party - "Cabletron systems")...it had a 9pin->PhoneNET adapter...the card also had 2 coax-esque connectors... -------------------- Spellcheck/Grammar Bandit and beholder of: -the Quadra/Centris Stick of Justice™ -the HTML Keyboard of Greater Knowledge™ -Compact Mac Wand of Power with Shocking Flyback Transformer Tip™ -------------------- Edited by - FireWire is fast on 16 Mar 2002 21:39:43
raWr Junior Member Tuvalu 491 Posts	Posted - 17 Mar 2002 : 05:50:16 sorry guys! I thought I was right, bot nooooo. It's a 15-pin male connector. Rerun? Fleet Covert Ops Padlock Magnet

No joke... they make wireless LAN cards nowadays! Anyway, I've got one of those 9-pin PhoneNET thingos for original Macs, darn company shipped it to me instead of a regular mini-DIN8 one. ~Coxy - Leader, Tactical Operations Unit 68k Macintosh Liberation Army 00014 Macs liberated.

Rerun? that'd be ThickNet, it should have oddball metal tracks instead of screw down lugs like a mac's monitor port, and i have no idea how it works. the coax-esque thingos are for ThinNet and they're bad news if one of the computers on a net goes down and most of the ones i have found have a 10baseT (RJ-45 socket) or a ThickNet connector on the card also. once in a great while you'll find one by itself on a card and it won't work even if you get all the crap to test it. if it's from DCA it might be a Token Ring card for talking to the IBM mainframe you might find in a dumpster (or filling a barge) someday so hold onto it. i think i got a second one from the stack of IIfx's, but i haven't checked the numbers. jt p.s. the connectors with the little holes for pins to poke into are the FEMALE connectors and they're intended for the insertion of those little pins inside the RFI shielding shell on a MALE connector. When it comes to Centronics connectors it's a little more complicated for sex determination, but not as bad as on a croc (ick!). Edited by - Trash80toG-4 on 17 Mar 2002 07:47:46
~Coxy Leader, Tactical Ops Unit Australia 2822 Posts	Posted - 17 Mar 2002 : 07:29:40 It's a really think coax cable, with weird clamp-on connectors that tap into the conductor. And that is the extent of my Thick-Net knowledge! ~Coxy - Leader, Tactical Operations Unit 68k Macintosh Liberation Army 00014 Macs liberated.

And that is the extent of my Thick-Net knowledge! maybe we can get marchie to write up an info sheet on early networking standards for 68k's as content for the site. i'm curious as to what kind of equipment and topology was used for ThickNet. terminology and identification characteristics for the cards/connectors would be a handy thing to have on the site. jt 8] p.s. wireless networks! what do you use for a freakin' firewall, aluminum foil? i'm having enough trouble with this newfangled interface crap for arpanet!
AnubisTTP Junior Member USA 308 Posts	Posted - 17 Mar 2002 : 11:52:14 If I remember correctly it is a bus topology, there are no hubs or anything, the cable just runs from computer to computer and there is a little metal T connector that you put at each computer so the cable can run both in and out of it. The connectors are called BNC connectors, which stands for British Naval Connector. They stopped using it because it was hard to maintain, if one of the T connections failed, it would take down the entire network. AnubisTTP 68k Macintosh Liberation Army Macs Liberated:15

I think that's Token Ring, but i'm not all that sure on the terminology and i don't remember the number of the one in storage to cross-check it, but that was token ring when i ran the numbers down. jt
Marchie Chaplain USA 911 Posts	Posted - 17 Mar 2002 : 14:56:02 Ethernet standards, ala Marchie. The ones that look like Mac-style video (DB-15) are AUI connectors, AKA ThickNet. These used hubs and such, and these are the connections you will often find on current routers for connecting to other networking equipment. I have NuBus cards with his type of connection, but no MAc ever shipped w/ it on the MoBo. ThinNet uses 75ohm sheilded coaxial cable. No hubs necesarily needed, although there could be. This is Ethernet useing a Bus topology, similar to PhoneNet/LocalTalk. Again, no Mac has shipped with this system installed. The most common type of system these days is Ethernet using UTP (Unsheilded Twisted Pair) cableing, with RJ-45 (8 pin connections kinda like phones use) connectors. You could also use Sheilded Twisted Pair, but you generally don't need to, and it's expensive. Always use a minimum of Cat6 cableing. Anything less will wind up with lots of line noise. These can be of the 10baseT or 100baseT stnadard. 10bT uses 4 wires, 100bT uses 8. The AAUI connectors (Apple AUI) are small, 15(?) pin funny looking things. The first MAcs to ship with Ethernet had these, and they require the use of an AAUI Adapter (10baseT adapters for sale from me in the Trading Post!) to convert them to 10bT, ThickNet or Thinnet. My IIfx has the following cards in it: Card w/ RJ-45 connection CArd w/ DB-15 ThinkNet only Card with AAUI conly Card w/ RJ45, ThickNet, AND THinNet (only one will work at a time) raWr's card has a 15 pin MALE connection... this is VERY odd. Macs have never(?) shipped with male port on them. I'm lost as to what it is. ~Marchie ~Chaplain Marchie Holder of the Compact Mac - -Stick of Justice, with Explodeing CRT head -Wand of Power with Shocking Flyback Transformer Tip ~~"We are all Mad here"~~

I'm lost as to what it is. thanks, Marchie, very cool. is ThinkNet a typo, a different standard or trade name? what kind of card was fw mentioning? did apple have an earlier AAUI connector? has anyone seen the mini centronics in use on anything but AAUI on a mac? raWr got the number of signals wrong, i figured he might have miscommunicated M/F also, otherwise i'm stumped, even game ports are female DB15. the only male DB connectors i have ever seen on a card or backplane are PC serial ports. very curious! jt
