Performa 475 + Dial-Up Internet

    In March 2013, in my review of Apple Macintosh Performa 475, I told Habré readers about an apple personal computer from the mid-90s. However, due to the lack of a network card on board this old man, the review did not examine the operation of the Apple Macintosh Performa 475 on the Internet. What was my surprise when I saw the first comment - people were eager to connect the Macintosh Performa 475 to the global network!

    Even the lack of a network card did not bother me a bit - many ways were suggested to connect the Macintosh to the World Wide Web, including through LocalTalk.

    Connect to the Internet? It's simple!

    Well at least about Dial-Up nobody mentioned ... While, and why not?

    I hope you have not forgotten what is necessary to access the Internet using a modem? Right! Modem. And you also need an Internet provider that provides access to the World Wide Web using dial-up connection over a telephone line.

    The modem was found quite quickly, but with providers providing dial-up Internet access, a rather interesting situation developed. Since there is practically no demand for dial-up Internet connection via a conventional (non-ADSL) modem in large cities, I could not find a single provider suitable for me in Moscow and the region.

    image

    It is possible that I was looking very poorly, and such providers exist, however, it is extremely unprofitable to use their services - in addition to paying for Internet access, you will also have to pay phone bills.

    Surely everyone remembers that before there was no time-based charging for telephone calls around the city, and many owners of modems occupied the telephone line all night. After all, during the day, households could expect an important call to their home phone (not everyone had mobile phones, especially grandparents), and Internet access in the dark (it seems like ROL from 2:00 to 7:00) cheaper.

    With the introduction of time-based billing for phone calls, the modem Internet began to hit twice - it was necessary to pay not only the access itself, but also telephone bills for hours of telephone calls.

    Your own provider.

    As you know, there should always be at least one way out of any situation. So in our case, you can refuse the services of third-party organizations and play the provider yourself. We just need to raise and configure the Dial-In server (incoming connection server), and the easiest way to do this is in the operating systems of the Windows family.

    To organize a modem connection and provide access to the Internet, you can use the built-in tools of the Windows operating system (starting with Win2K and higher), using the wizard to create a new connection on a server computer. Work with the wizard is simple and understandable, however, just in case, I will give a small instruction in pictures applicable for Windows XP.

    We indicate which modem we will use to establish the connection.

    We do not need virtual private connections, we prohibit.

    We tick off the user under which authorization will occur when the connection is established. The user account must be valid (not disabled) and have a password.

    It should be noted that the use of telephone modems implies the presence of a telephone line with all the ensuing consequences. So, for example, it is desirable to have a PBX to establish communication between two modems. Desirable, but not necessary. There are several ways to do without it:

    • The first way is to connect your Macintosh Performa 475 with a null modem cable to a computer that has Internet access. No modems at all.
    • The second way - you can find modems that can work on a dedicated line , and with their help connect to a computer with Internet access.
    • A third method - a connection with two conventional modems without using the ATS . Requires skill with a soldering iron. The most interesting way.

    Null modem connection.

    Using a null modem cable I did not like for its simplicity. In addition, you can accidentally burn the COM port and / or the computer itself, because the null-modem connection has no galvanic isolation - if you have an old Soviet wiring without grounding, an unexpected thing can happen.

    Using a dedicated line is the second easiest way to establish a dial-up modem connection without a PBX. Unfortunately, modems "for home use" on a dedicated line do not know how to work. This is the prerogative of only expensive professional modems, which, alas, I did not have.

    A pretty good option is to use regular modems to “emulate” the presence of the exchange. I would choose this method if I didn’t completely accidentally collapse with the NEC (Nitsuko) 2464 TX office PBX, which I will use in my experiments.

    Macintosh and COM ports.

    Another surprise awaits us when you connect the modem to the Apple Macintosh Performa 475, a serial port is designed as a connector MiniDIN-8 . To connect a modem, we need an adapter, the circuit of which is given below.

    image

    The main difficulty in the manufacture of the adapter lies in the search for the connector Mini-DIN-8 (Male). In a radio parts store known for its high prices, the name of which I will not voice, these connectors are offered to buy for 140 rubles.

    The result should be something like this.

    Modem selection.

    MacOS 8.1 supports some out-of-the-box modem models, but you can only find these modems in the museum. Perhaps the only exceptions are US Robotics modems, which can still be found on the mezzanines of our vast Motherland.

    image

    If you have a modem from this manufacturer, you can select the appropriate driver from the list of supported modems.

    Unfortunately, after I got three Zyxel Omni 56K modems (PRO, Plus and PCI Plus), all the other modems that I have have safely gone to landfill, including an external 33.6K Sprotster.

    image

    If your model was not in the list of supported modems, you can search for drivers on the manufacturer’s website. However, even if MacOS drivers existed for your modem (and this is not at all a fact), downloading them will not be easy - often the driver links for outdated products turn out to be dead. Be patient, and may strength come with you.

    image

    For external Zyxel Omni 56K modems, drivers for MacOS 8.1 - 8.5 can be downloaded from here .

    If the manufacturer of the modem did not bother with MacOS 8.1 support for your brainchild, you can use the utilityApple Modem Script Generator , or search for ready-made modem scripts on the Internet.

    Spacewalk.

    It's time to surf the web.
    I remind you once again that the characteristics of the Apple Macintosh Performa 475 are rather modest, and not very suitable for modern Web 2.0 : the processor clock speed is only 25 MHz, and there was very little RAM scrambled - only 36 MB. For a 1994-1996 computer, these are quite worthy features, but you yourself understand ...
