Commodore Amiga 4000, Networking to a PC
I have a Amiga 4000 in the following specs
060 Cyperstorm with 128MB ram (50 whole mega hertz) Toccata Sound card Cybergraph 643D 4MB GFX card Amiganet Network card (15 pin D-type and BNC) GVP 4000 HC+8 SCSI card + 4GB SCSI HDD 154MB total mem, 8GB total HDD space Understandably, most people must think I am mad, with XP making networking so easy why bother with an Amiga? I fancy the challenge, to see the A4000 on the internet. the problem is I need to know the pin out of the D-type 15 way and possibly the wiring to the RJ45, I would use the BNC but my main PC will not accept the old BNC cards. Can someone help? |

You cannot just make a lead to connect the 15 way D to RJ45. Another option might be to buy an old 10Mb hub as these often have BNC and RJ45 connections. You then need the screened lead, two T pieces and two terminators. |

Re: Commodore Amiga 4000, Networking to a PC
Paul is quite correct, there is no way to connect an AUI connector to a UTP cable. The AUI port is for an *external* transceiver, and originally all Ethernet interfaces worked that way. Later onboard transceivers were introduced, so you got RJ45 or BNC connectors on the card.
Why do you think you can't get a network card with a BNC interface for your PC? Presumably you're referring to ISA and PCI bus cards, but there are lots of PCI cards which have a BNC interface. If you really, really need one let me know and I'll have a look in the junk box Best regards, Paul |

Re: Commodore Amiga 4000, Networking to a PC
I have a few AUI-to-RJ45 transceivers here. I even use them, sometimes, to connect old Sun and DEC gear to modern twisted-pair ethernets. I'll see if I can find a spare one, if you have no luck.
I can also offer you a hub that'll connect a BNC ethernet to a twisted-pair ethernet. It's huge and heavy, of course, but that shouldn't be an obstacle on this forum... |

Re: Commodore Amiga 4000, Networking to a PC
Cheers, I have found a CenterCOM 210TS Twisted pair Transceiver (IEEE802.3) But this box says its a MAU, is this different than AUI, also when it says twisted pair, does this mean that I need a striate through cable or a crossover cable?
Its a bit shameful a computer technician asking these kind of questions but I have no idea as I started on RJ45. The other problem is I have never EVER networked an Amiga, I don't know where to start! so many people say you can network a Amiga to a PC and share the internet, sounds easy.... I see no network option from Workbench and after downloading the drivers disk, it makes even less sense as the driver disk uses a file manager like Opus. |

Re: Commodore Amiga 4000, Networking to a PC
MAU = Media Attachment Unit
AUI = Attachment Unit Interface So, a transceiver is an MAU, and the connector that connects it to the host is an AUI. As for the cable, if you connect the transceiver to a hub, then use a straight cable. If you connect the transceiver to a PC (or another transceiver), you'll need a crossover cable. Beware that some hubs have a switch to make one port a crossover port, or they may auto-switch. |
