Apple Ethernet cards
Apple Ethernet cards are the network interface cards Apple sold to put Macintosh computers without built-in Ethernet onto 10 Mbit/s Ethernet. The first was the EtherTalk Interface Card for the Macintosh II, introduced with EtherTalk 1.0 software in August 1987 and later renamed the EtherTalk NB Card.[1] It was followed by the Ethernet NB Card for NuBus, the Ethernet LC Card for the LC processor-direct slot, and cards for the communications slots of the LC 575, 630, 5200 and later families.

EtherTalk cards
[edit | edit source]Apple bought the EtherTalk card from 3Com and sold it under its own name; 3Com sold the same board as the EtherLink NB.[9] The card has a BNC connector for thin Ethernet with an on-board transceiver, selected by a jumper, and a 15-pin AUI connector for an external transceiver on thick Ethernet. Apple gives the power as 6.5 W maximum from +5 V and 3.6 W from +12 V, with 32K of ROM.[10][11] Its two specification sheets give 16K and 64K of dual-ported packet buffer RAM; the revision history says the larger 64K buffers came with revision L.[11][10][1] Each card carries its own Ethernet address, stored on the card and printed on a label on the back of the board.[12]
Revisions
[edit | edit source]| Revision | Date | Apple assembly | Change |
|---|---|---|---|
| A to D | 1987 | – | First production |
| J | March 1988 | 2680-06 | Fixed rare data corruption when the card retransmitted a packet after a collision, and a clash with NuBus cards using addresses in the $xxxFxxx range. Reworked earlier cards were relabelled G to J (A became G, B became H and so on). |
| K | January 1989 | 2680-07 | Fixed timing that assumed a six-slot NuBus machine, which upset three-slot machines such as the IIcx |
| L | December 1989 | 2680-08 | New layout with new ROMs and no cuts and jumpers; larger buffers; NuBus fixes needed by the IIfx |
| M | November 1990 | 2680-08 | Manufacturing process change only |
Dates and changes are from Apple's EtherTalk history; assembly numbers from its revision list.[1][9][13] Apple offered a free upgrade to revision J from May to October 1988, but no upgrade to K or L.[1]
Apple's articles do not agree on which revisions suit which machine. All accept J, K, L or M in the Macintosh II and IIx, and K or later in the IIcx. The 1991 revision list asks for L or M in the IIfx, IIsi and IIci; the EtherTalk history and the System 7 note also accept K in the IIfx, and K in the IIci only without on-board video.[9][1][2] On a IIci a revision K card with EtherTalk 2.0.1 or 2.0.2 runs slowly when on-board video is set to 4 colours or more. Fit a revision L or M card, use a video card, or run on-board video in black and white.[14]
Software
[edit | edit source]EtherTalk 2.0 (June 1989) added AppleTalk Phase 2 and changed the packet format, so 2.0 nodes cannot see 1.x nodes without a router running both. EtherTalk 2.0.1 (October 1989) and 2.0.2 (March 1990) only changed the .ENET driver in the System file, adding delays to suit the faster IIcx, IIci and IIfx; the EtherTalk file in the System Folder kept the same version.[1] Apple gave a limit of 254 active EtherTalk users, bridges included, on one Ethernet. A Macintosh II with an EtherTalk card cannot bridge LocalTalk and Ethernet by itself.[12]
Testing
[edit | edit source]Apple's bench test is MacTest II, which has a one-card test and a two-card test against a known-good card. Set the jumper to thin cable and fit a BNC T-connector with two terminators from kit 077-0256 as a loopback. For the two-card test, link the two cards with thin net test cable 077-0257, with a T-connector and terminator at each end. The two-card test finds faults the one-card test misses, and neither test checks the 15-pin thick Ethernet connector. Reset the jumper before the card goes back into use.[15] The later MacTest MP test for the EtherTalk NB card runs on the II, IIx, IIcx and IIfx but not the IIci or IIsi.[16]
Ethernet NB Card
[edit | edit source]The Ethernet NB Card is a NuBus bus-master card with its own Motorola 68000 at 10 MHz, memory and real-time multitasking operating system, and a National Semiconductor DP83932 SONIC controller.[17][18] It has 512K of RAM as four surface-mounted 256K × 4 SOJ chips, and four ZIP sockets for a further 512K (four 256K × 4 chips) or 2 MB (four 1M × 4 chips), at 120 ns or faster; Apple's own upgrade was M0145LL/A and its suggested part the Toshiba TC514400AZ.[19][18] The card works internally on a 16-bit path, and its processor mostly manages DMA.[20] Apple put the built-in Ethernet of a Quadra at 15 to 20 per cent faster, because it uses DMA to main memory, avoids NuBus transfers and runs at the system bus clock.[21] Remove the RAM chips from the ZIP sockets before returning a card to Apple for exchange.[8]
The network connector is Apple's Ethernet port, the 14-position AAUI. A media adapter plugs into it: the Apple Ethernet Thin Coax Transceiver (M0329LL/A), the Twisted-Pair Transceiver (M0437LL/A) or the AUI Adapter (M0432LL/A) for thick coax and other media.[17][22] Keep AAUI cables under 1.5 m.[23]
Apple's power figures differ between sheets: 3.96 W at 5 V in one note, and 7.5 W maximum with a 4 W average in the 1993 specification. The same note gives 13.9 W as the recommended limit per NuBus slot and 1.165 A as the card's total draw with an external AAUI transceiver.[23][3] The card needs a NuBus slot, or the NuBus adapter in a IIsi or Quadra 610, System 6.0.4 or later or A/UX 2.0, and AppleTalk Phase 2 on the network.[18][3]
Ethernet NB Twisted-Pair Card
[edit | edit source]The NB Twisted-Pair Card has a built-in RJ-45 10BASE-T port, 128K of RAM and a DP83934 SONIC-T controller, and draws 3.75 W at most (2 W average). It needs an IEEE 802.3 10BASE-T hub.[3]
Ethernet LC Card
[edit | edit source]The Ethernet LC Card fits the processor-direct slot of the Macintosh LC family, the Color Classic and the Quadra 605. It uses the DP83932 SONIC, draws under 4 W and has the same Apple Ethernet port and media adapters as the Ethernet NB Card.[24][4][5] Like the NB card it uses a 16-bit data path.[20] In the 630 family it goes in the LC PDS slot, which lets a 630 have an internal modem in the communications slot as well as Ethernet.[25]
The card needs a newer ROM in later machines. The LC II needs a ROM upgrade carrying a new driver.[26] In the LC III and LC 575 an old card gives "could not switch to EtherTalk" when Ethernet is selected; the cure is a card with the new ROM and EtherTalk installed from System 7.1 or later disks.[27] The new card is board assembly 670-2008 and the old one 670-4443 with ROM 341-0842. Apple's Tech Info Library gives the new ROM as 341-0470 and its module identification manual as 341-4070, introduced in March 1992.[27][8] The Macintosh Processor Upgrade cannot be fitted while an LC-style card such as this one is in place.[28]
Ethernet LC Twisted-Pair Card
[edit | edit source]
The LC Twisted-Pair Card has a built-in RJ-45 10BASE-T port and a DP83934 SONIC-T controller, and draws 1.5 W at most (1 W average).[4]
Twisted-pair and thin coax cards
[edit | edit source]Apple's cards reach the three Ethernet media in two ways. Cards with the Apple Ethernet port (Ethernet NB, Ethernet LC, Ethernet CS AAUI) take an external transceiver: thin coax (10BASE2) through the Thin Coax Transceiver, unshielded twisted pair (10BASE-T) through the Twisted-Pair Transceiver, and thick coax or fibre through the AUI Adapter. Other cards have the transceiver built in: the NB and LC Twisted-Pair cards have an RJ-45 port, the CS Twisted Pair card connects to 10BASE-T, and the CS Thin Coax card connects straight to 10BASE2 thin coax.[17][3][4][6] The comm slot II range repeats the choice with a 10BASE-T, a 10BASE2 and an AAUI card.[7]
On thin coax, the Thin Coax Transceiver terminates the cable itself when one of its two BNC connectors is free, and Apple's 5 m and 13 m cables terminate when an end is left unconnected. An older EtherTalk NB card at the end of a segment needs a terminator on its T-connector.[29] Apple's NB hardware has no way to turn off the 10BASE-T link beat signal, so it will not work with early twisted-pair hubs that cannot handle link beat.[30]
Communications slot cards
[edit | edit source]The communications slot first appeared in the Macintosh LC 575, where Apple's developer note calls it a socket for a communications interface that is not a general expansion connector.[31] It is a 112-pin slot with a 32-bit data path, used in the 575, 630, 5200 and 5300 families and the Performa 6200 and 6300 series. Apple made four cards for it: the Ethernet CS Twisted Pair Card, the Ethernet CS Thin Coax Card, the Ethernet CS AAUI Card and the Express Fax/Modem.[6] All of them work in the Performa 575.[32] A machine has only one communications slot, so it takes either the modem or an Ethernet card there.[25] The Apple IIe Card does not work in an LC 575 with anything fitted in the communications slot.[33]
Apple later named this slot comm slot I to tell it apart from the PCI-based slot in the Power Macintosh 5400.[6]
Comm slot II cards
[edit | edit source]Comm slot II, in the Power Macintosh 5400, 5500, 6400 and 6500 and the Performa 6360 and 6400, is a PCI-based 112-pin slot. It is keyed at the opposite end from comm slot I, so a comm slot I card lined up with the notches would face the wrong way, and the two slots are not fully signal compatible. Only serial modem cards built with both cut-outs work in either.[7][34] The Ethernet CS II range has 10BASE-T (M4772ZM/A), 10BASE2 (M4773ZM/A) and AAUI (M4774ZM/A) cards; the 5400/120 and 6400/200 shipped with the 10BASE-T card.[7] The cards and their software work only under Open Transport.[35]
Troubleshooting
[edit | edit source]| Symptom | Probable cause | Action |
|---|---|---|
| IIcx fails to boot, crashes or runs the network very slowly, often with no other card fitted | EtherTalk card older than revision K | Fit a revision K or later card[1] |
| IIci network slow with on-board video at 4 colours or more | Revision K EtherTalk card with EtherTalk 2.0.1 or 2.0.2 | Use a revision L or M card, a video card, or 1-bit on-board video[14] |
| Ethernet NB card installed under System 7.0 or 7.0.1 but not working | EtherTalk on those system disks has no Ethernet NB driver | Install EtherTalk 2.5.1 or later[36] |
| "Could not switch to EtherTalk" with an Ethernet LC card in an LC III or LC 575 | Card with the old ROM | Use a card with the new ROM and install EtherTalk from System 7.1 or later[27] |
| Ethernet LC card not working in an LC II | Old ROM and driver | Fit the ROM upgrade[26] |
| No link to an old twisted-pair hub | Card sends link beat, which the hub cannot handle | Use a 10BASE-T hub[30] |
| Thin coax segment unreliable | Missing termination at the end of the segment | Leave a transceiver connector or cable end free, or fit a terminator to the T-connector[29] |
| Power Macintosh 5400 or 6400 cannot select EtherTalk | Classic AppleTalk in use; the CS II card needs Open Transport | Switch to Open Transport, restart and select Ethernet[35] |
| MacIPX error −43 on a comm slot II machine | Missing Ethernet support for MacIPX | Install the 6360/64xx/54xx Update or Mac OS 7.6[37] |
For an EtherTalk card suspected of a hardware fault, run the loopback tests described under Testing.[15]
