  1. Connecting old Macintosh to the net using serial

    First priority is to get the iBook on the net. Once you can access something like google.com, you should be good. Set the gateway on the se/30 to the one on the iBook. If the iBook can connect to the internet it should be good. Set the ip on the se/30 to something like the one on the iBook but changing the last number. Ignore all the checkboxes. If you have a spare linux machine, you can test the serial adapter that way using getty. Open ZTerm on the SE/30 and run: /usr/sbin/getty -L <serial port> <baudrate> on the linux machine.
  2. Connecting old Macintosh to the net using serial

    Phew lots to work with! About FreePPP: For starters, I'd try it with MacPPP. Not sure how you got FreePPP running, it just froze the computer when I tried. Network issues: I had exactly the same issue with my iBook G4, same OS. Don't use wifi, that's just generally a bad idea to start. Plug it into your router or hub using an ethernet cable, and it should automatically get the IP address. If that's not an option, see the attached screenshot for the router settings. Your gateway is the "Router:" option. USB -> Serial: Ignore all the extra options in the networking panel, they are not going to be used. you want to use tty.usbserial, not cu.usbserial. The full command in your case would be: pppd <BAUD SET IN MacPPP> tty.usbserial local persist passive maxfail 0 proxyarp <IP OF THE iBook>:<IP OF THE SE/30> The ip of the SE/30 should be similar.. If the computer is, make the SE/30 something like The ip should be <gateway without last number>.<some number>, which in my example, the gateway is, so the ip is Proxy script: you -might- not have to use it.. In my case, the Macintosh Classic could not connect to outside domains for some reason, and could only ping/connect to IP addresses within my network (the router, the web server on my other computer, etc), but give it a try. Try some of the things I listed above, if you still have issues send a PM my way and we can try and fix it there. I'd love to see your SE/30 on the internet! I was not able to get my Plus on the internet (the OS said it ran out of ram, even though it had the same as my classic).
  3. 5 year post bump... That's gotta be the record holder in my book for oldest post bumped
  4. Connecting old Macintosh to the net using serial

    Thanks! Hopefully it will clear up confusion for people trying to do it these many years later... After all, it's the cheapest way I've seen so far to connect old macs to the internet.
  5. A topic (that is currently pinned) exists with a tutorial for connecting your Macintosh to the internet using USB -> serial, but it is very outdated and I ran into several issues while following it. I'm going to add further instruction to it (which is mostly copied from a reply to a thread I made). For starters, some amazon links! USB->Serial: https://www.amazon.com/gp/product/B00J4N9T9C/ RS422->RS232: https://www.amazon.com/gp/product/B000068OEQ/ Original page (you'll need this for most of the tutorial): There were a few things I had to do differently. First, you cannot do it on a modern system for some reason. The PPP daemon for Linux just doesn't do what you would need, and the one for a later OS X (in my case 10.7) would not run. I ended up using my iBook G4, but had to get ancient PowerPC drivers for the USB->Serial adapter from https://web.archive.org/web/20071114081401/http://www.prolific.com.tw:80/eng/downloads.asp?ID=31. In the end I got a nice tty.usbmodem to work with. Nowhere on any pages of this thread does it tell how to properly setup MacTCP, which I had to experiment with for quite a while. Here are the steps I did: Set "Obtain Address" to manual Set gateway address as your router's IP address (in my case, Set "Class" (in the IP Address settings) to C Make sure your subnet is correct (in my case, Set your domain name servers to: * URL: ignore.com (literally just this) IP: URL: ignore.com IP: Click "OK" You should have a box for "IP Address" when you click ok. Set that to something similar to one on your network (for example, gateway is, ip is Click the close button and restart * I have not yet been able to resolve any domain name outside the router, which I have yet to figure out. I will include instructions and code for a simple proxy. Once MacTCP is setup, make a MacPPP profile with no phone number and baudrate set at 57600. Assuming you've already got drivers figured out for your system, connect the vintage mac to your internet-connected mac and open a terminal to type the commands in the above thread. Make sure the baudrate is the same as you set in MacPPP. Hit "Open" on MacPPP and -whoosh- you're connected to the internet! If anyone has ideas on how to fix name resolution, please reach out to me! Currently its very tricky to get anything done using my script. Proxy Instructions: Make sure you have a simple web server (with PHP installed) running on some other computer of your home network that CAN access the outside world. In your WWW directory (I won't be explaining setup since there are plenty of tutorials) create a file called proxy.php and put this inside: <?php $ip = ""; //Get the raw html. $furl=trim($_GET["url"]); $raw = file_get_contents($furl); //proxy everything $replacethis="href='"; $replacestring="href='http://$ip/proxy.php?url="; $raw=str_replace($replacethis,$replacestring,$raw); $replacethis="href=\""; $replacestring="href=\"http://$ip/proxy.php?url="; $raw=str_replace($replacethis,$replacestring,$raw); $replacethis="<head>"; $replacestring="<head><base href='http://$ip/proxy.php?url=".$_GET['url']."'>"; $raw=str_replace($replacethis,$replacestring,$raw); //Echo the website html echo $raw; ?> Change $ip to the IP of your computer (you can find this with ifconfig in linux and mac, or ipconfig in windows), and connect to a website on your mac using: http://<YOUR IP>/proxy.php?url=<URL YOU WANT TO VISIT> This will not only fix the DNS problem, but also allows you to access HTTPS sites which are not supported on your mac.

    Did you make this?
  7. Info needed

    Ah so it's really that simple? Just sign up when the next runs? April sounds good... Should be ready by then to start my "project"
  8. Info needed

    Who can tell me all the little details about the RetroChallenge? Is it basically to choose a project and try to finish it within the month while keeping updates? When might the next one be?
  9. Mac SE Problems

    Glad to hear that the floppy works again! Sometimes it is just the simplest connections that make the difference. Does the hard drive still spin up? Maybe it's stuck...
  10. PowerBook 150 - screens all destroyed?!

    Oh boy! Sad to look at the pics My PB160 is just fine still, and has been exposed to lots of humidity before (once causing an issue with the screen as well). I did see one on E-Bay a while back (long long while back) that had the same issue... I believe the seller said something about possible heat exposure?
  11. Mac SE Problems

    In my personal opinion, every classic mac is worth saving (unless it has serious battery corrosion beyond repair). Look up some tutorials on youtube on how to clean the floppy drive; that would be my first guess. You may also have bumped something while fiddling with the hard drive, so double check the connections there. Also, it should work just fine with an external floppy (though I do not own an SE/30 so I cannot say for sure). As for the hard drive, I would find a system 6 disk tools, since it's lighter than system 7. If your model has 4mb ram, it would also be a good choice for the OS in general since it's lighter. Try formatting the hard drive multiple times, and also verify it multiple times. I had an issue on my powerbook where I accidentally unplugged it (and the battery is bad) causing it to force shut down. It would not boot after that, and required a fresh install of the system folder. Also from my experience (though it looks like you were able to get it to boot fine), I would use a much older system than a powerbook g3 to make your boot floppies. My method is to use my iBook G3 with a USB floppy to copy the disk images to my PB 160, and then use DiskCopy to write them to disks.
  12. Retr0Bright Questions

    AlpineRaven: Do you have a suggestion/source for an indoor UV lamp? I can't seem to find one that would fit the purpose that isn't outrageously expensive.

    luckybob: My plan is like yours; no plastic wrap and keep applying. By reading some failure stories, it seems the common point is the plastic wrap with an uneven coating.
  14. Retr0Bright Questions

    Thanks for all the info! Very interesting about the emblem. Didn't know it was assembled that way I believe I will try not using the developer method on the keys, since it will still be just as easy. Using the developer on the case is much easier though. I have read many horror stories and seen sad pictures (on this forum and elsewhere) where the treatment process failed, and my number one priority is to avoid that. I'll check out the first video, as I don't want to ruin the CRT (obviously), though I've seen the rest. Big fan of The 8-Bit Guy and his work, and I've gotten lots of inspiration from him.
  15. Should I put OS X back on this iBook G3?

    While most people would just stick to OS9, I've been quite happy with OS X 10.2. 10.4 will run on it, but it is sluggish. The advantage to upgrading is obviously the software benefits, but I wouldn't recommend doing that unless you also had an OS9 installation. My G3 has OS9 and 10.2 installed, and I use both partitions. If you want WIFI, setup a newer computer as an access point, and either make it hidden and open, or use WEP encryption.
