Null modem cable and/or adapter for a Mac SE/30 (pref. UK)

    I've got an old SE/30 that I want to hook up to the Internet. Now the
    machine has no built in Ethernet card (I've looked and the SE/30
    specific ones are like pixie dust) and only has those funky little 8-
    pin serial ports on the back.

    I figured I could just give it a PPP connection from another box IF I
    could find an adapter from the 8-pin port to a normal DB9 male port,
    and then stick a null modem cable between that and another box.

    Do such adapters exist? Are they still sold? In the UK / EU? What
    kinds of speeds can the SE/30's serial port support?

    I found one prebuilt Mini->DB9 female null modem cable (http:// but 26
    bucks + shipping + UK duty and VAT make that less attractive.

    Thanks in advance,

    Wow, that brings back memories. The first Mac I had on the net was an
    SE/30. I got an Ethernet card for it, way back when. It still
    works. It's OK for email and newsgroups, forget web browsing.

    Wow. Pretty cool. Yep, it's *much* faster serving up web pages than
    rendering them. Gives a whole new meaning to "Can dish it out, but
    can't take it"! LOL!

    BTW, to the OP: there is currently an SE/30 Ethernet card on eBay:


    and an actual SE/30:

  4. This is in Sweden, but they have a bunch of Ethernet cards for old

    Scroll down to "(060-3500)". It's 250 SEK. Seems they have one (1)
    left in stock.

  5. Hate to admit it, but not even yours truly is paahfect... I forgot
    the OP's question about null modem cables. You can find the pinouts and
    other tips here: <>

    If you don't want to solder the cables yourself, have
    ready-made modem cables for the Mac here:
    It's article no (C-28H-3), and it's 250 SEK.

    If you don't want to solder the cables yourself, have
    Any idea what's at the other end of that cable, a DB9 male port I
    assume into which I can then plug a normal null-modem cable?

    Ordered both the SE/30 network card (those are damn hard to find) and
    the serial cable. Cheers Bjarne.

  8. It's a "Mac standard" Mini-DIN 8 pin.

  9. Glad to help. :) I've bought various Mac stuff from macdata since
    the mid-nineties, and have only good things to say about them.
