  1. 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 serial, but it is very outdated and I ran into several issues while following it.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, 192.168.0.1) Set "Class" (in the IP Address settings) to C Make sure your subnet is correct (in my case, 255.255.255.0) Set your domain name servers to: * URL: ignore.com (literally just this) IP: 8.8.8.8 URL: ignore.com IP: 8.8.4.4 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 192.168.0.1, ip is 192.168.0.123) 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 = "192.168.0.110"; //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.

    So much for trying to make space.... But for $15 I couldn't pass it up.

    Hah funny story... While using it and installing TenFourFox, Classic mode, and Quake III the CRT suddenly shut down and wouldn't come back. I had almost given up hope for it, as it was just $15, when I thought "old computers could pretty easily be fixed by a big whack on the side". And what do ya know, it worked! Coughed back to life after a pretty sizeable whack on the side. Lol!

    1.25ghz. Guess it can't run OS 9

    Ah nevermind... For some reason it wouldn't take my 10.2 disc. Upgraded to 1gb of ram and replaced the battery. Putting 10.4 on it

    Only one issue... It refuses to boot from CD, even though it can read them just fine.

    Reviving a Macintosh Plus.

    Got this one from Johnnya101. Had only a vertical line on the screen. I snapped the connector on the red wire so I had to replace that... the rest was pretty straightforward. Just used a solder-sucker and got rid of the old stuff around the problem areas and re-soldered.
  8. yeah... i actually noticed that too.. let me check the backend real quick; I did a domain change recently and I think it broke. Edit: phew... databases aren't working. Time to fix that, a lot of my sites just broke lol.
  9. Feel free to check out http://nocss.techedison.net I did a similar thing.

    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?
  11. TechEdison

    Info needed

    Yeah I sorta gave up when it got super behind and never got finished... I completed my project, the midway report mentioned that my blog was down even though it was not. Messaged multiple times and nothing happened. at least i finished the site... http://nocss.techedison.net/

    John's Classic Restoration Thread

    Awesome! Glad to see it fully restored.
  13. Congrats! Glad you took another closer look at it. The line in the middle is indeed normal. It is the split point between the top and bottom half. Like I said above, the passive matrix displays are split in 2 to help with rendering.
  14. These two spots jump out at me.
  15. There isn’t much else to explain except that literally nothing happens when powered on. I know the analog board and crt are good because I tested it with another board. Picture of the board can be seen below. Where do I start? I’m sure even if the caps were bad it would do *something*

    SE/30 nothing happens when powered on

    In total: missing components, cap goo, no ram. And of course, broken crt. It was obviously from that case. Salvaged parts off the corroded one and gave it a good wash. Haven’t tested inputs yet. The floppy drive didn’t work so I’ll have to tear into it and clean it.

    IT LIVES!

    SE/30 nothing happens when powered on

    That was after washing the board. It worked for a couple minutes and then failed again and is doing what it did before. When it was working though, it chimed and everything. Even the sad Mac without rom or ram.

    SE/30 nothing happens when powered on

    SUCCESS!!! Well sort of... it has gone back to the state it was before, but it did work for a short few minutes!!

    SE/30 nothing happens when powered on

    Still have yet to figure this out.

    SE/30 nothing happens when powered on

    Perfect movie scene for this. I got super excited when the screen lit up in all its glory
  22. TechEdison

    SE/30 nothing happens when powered on

    Alright so next update: it acts the same with or without ram/rom.
  23. TechEdison

    SE/30 nothing happens when powered on

    I’m feeling great. I just transferred tiny parts over by hand
  24. TechEdison

    SE/30 nothing happens when powered on

    MAN! I’m on a roll tonight! What next!

    SE/30 nothing happens when powered on

    FOUND OUR PROBLEM! thanks to reading the thread posted by @techknight I did some poking around and sure enough, L14 is completely missing! Gonna grab that off the other SE/30 board and see if I can get this one fired up. im also missing c74 and r35 (though r35 looks like it was never there to begin with). Hopefully they are still on the other board.
