Linking Macintosh Classic II to another Mac.

I was wondering if I was able to link a Macintosh Classic II to a Power Macintosh G3 AIO. The modem ports on the back are a little different. If I am able to link them, am I able to make the G3 a "host" for the classic II to browse the web through? Or can I just do file transfers? If you have the information, please tell me. Thank you.

PhoneNet?

Hey,

If you're using PhoneNet or a variant of it, you can use the printer ports to make the connection.

What's phone net?

What is phone net? And the Power Macintosh G3 modem port has one more extra pin on the socket, I don't know if the two machines are able to connect to each other because of that. If they are, tell me someone.

Phonenet: A variation of [url

Phonenet: A variation of Localtalk.

Each Mac gets a transciever that connects to the printer or modem port (and the extra pin on the G3 won't matter) and a length of telephone cable goes between the two transcievers. Endpoints on the network needed termination.

A handy hack was to splice it into your existing home telephone jacks using the unused wires (back when most had just one phone number per household).

Tons of 'em available on ebay, and likely a whole lot of them unused in the basements of many Applefritter users.

No no no no.

What I'm trying to say, I have pictures below. Can I, Using the modem port on my classic II, directly connect to the Power Macintosh's modem port, then through the Power Macintosh to the Ethernet. Will I be able to get internet to my classic II through the G3??? Pics to explain:

Directly links to Ethernet.

These pictures may be a bit blurry. Sorry about that. I also want to know what the maximum image size is.

printer cable works too

You can use a printer cable as well, you're just limited to the one connection.

If you go that route, you'd want to run a bridge on the AIO to pass tcp/ip on through (as TCP-over-Appletalk, whatever that's called.) That's called multihoming when you run more than one TCP/IP port on a single machine. OS X has multihoming built-in, but I doubt it can even see the AppleTalk/serial port as a viable port. I bet a classic MOS is the only way to do this.

I know IPNetRouter can do it, but it costs $100. Anyone know of a free SW bridge? I was thinking LaserWriter bridge could do it, but now I'm recalling that it only passes AppleTalk packets.

There are ethernet adapters for the AppleTalk/serial port. Not all pass TCP/IP though, so you'd have to do some research to find one that works.

ps: don't worry about the ports being different, the extra pin on the AIO's 'Geoport' is simply a 5V power tap, all other pins are the same (basically) as on your Classic II.

er..what?

What are you no, no, no-ing at?

If you're asking if plugging modem ports together will let you use dial-up software on the Classic to connect to the internet with the G3 acting as some sort of magic modem, then no.

You can use Apple's localtalk bridge software on the G3 to allow the Classic access to your ethernet. TCP (and by TCP we're referring to teh Internets) is spotty at best through the localtalk bridge, but on a Classic II your internet use will be severely constrained anyway. You will need TCP software installed on the Classic.

There's enough info in this thread now for you to be making good use of Google and the other links provided further up. Read up on Localtalk, Apple Localtalk Bridge software, and maybe even search through Jag's House and other sites for 'getting old Macs on the net' or similar.

Got it.

I got LocalTalk control panel for the G3. The classic II is detecting local talk, I'm having trouble setting up the IP and stuff like that. I'm running a control panel item called MacTCP on the Classic II. I don't know what to do for all the configuration and things. Please help if you can. Thank you.

I need help.

I'm stumped. I got the two mac's linked. I did what the site said. But it's not helping. Do I run local talk control panel on G3 or Classic II? Need help.

if you can acquire it.you can connect rj45 and localtalk.so you can use rj45 ethernet and db8.but use db8 has a little problem,you need a phonenet one computer use one phonenet to another one.but this one speed is so slowly.I tried it transfer 10MB files,it need 30 min,if you just trasfer files,you can wait it.just suggest.
