    My SE/30 died!

    For some reason it's no longer making the hissing sound. Tonight it booted up and then cut out after a few seconds, then popped back on with an "A System Error Occurred" for a few seconds, then the screen went out again. After that I tried turning it on several times and the fan came on but no video, no startup chime, and no HD activity. My SE board still works fine, so looks like I'll be an SE guy for a while... Here are some pictures of the logic board, complete with my successful kludge fix for vertical pinstripes:

    MacBottom HD/Modem Modernization

    Thanks. The cable is just a standard Mac modem DB-25 / RS-232 cable like this one on eBay.

    MacBottom HD/Modem Modernization

    So I got a nonworking MacBottom HD / Modem with the purchase of my SE/30 and decided to modernize it. I swapped out the dead SCSI HD for a SCSI2HD (after 3D printing a bracket for it) and the old modem for a GuruModem RS-232 WiFi Modem. I used a 12V -> 5V microUSB converter to get proper power to the modem. It's kind of a mess in there, but everything works including the HD activity LED! Now I've got a reliable backup SCSI HD, I can log on to BBS's, and I can transfer files to and from any old Mac. What's slick about the GuruModem is that you can FTP to servers (like my MacBook Pro running FTPServer), download files to its microSD card, and then transfer those files to an old Mac via zmodem protocol.

    My SE/30 died!

    And this is why I said "for now"... The screen just cut out again after 3 days and it won't come back on. It turns out that it's not the analog board, as my SE logic board works just fine with it. Any idea what would cause such intermittent issues? Just before the SE/30 died I noticed that the serial ports were only intermittently working...

    My SE/30 died!

    I was able to find a cheap Mac SE with a dead HD on Craigslist and used the analog board from it. All is good again for now...

    My SE/30 died!

    Well it's not that either - I swapped out the working barrel rectifier from my Classic analog board and got the same result...

    My SE/30 died!

    And I should also say this happens in either direction.

    My SE/30 died!

    So I replaced all the caps and the flyback on the analog board, and it worked for a couple of minutes before it died again - nuts... There's now a hissing noise, and DMS suggests testing the barrel rectifier at CR2. I get continuity through the barrel rectifier for about 2 seconds, then the ohms start climbing and then my multimeter overloads to 0L but no continuity sound. Does this mean it's good or bad?

    My SE/30 died!

    I've got the part number (157-026C Flyback) and they go for $99 on ePay. But I don't even know for sure if that's my issue. I think I'll clean up the solder on the flyback and replace the capacitors and see what shakes out, unless someone has a better idea...

    My SE/30 died!

    I was using my SE/30 today when a "lightning bolt" shot down my screen and then it went blank. I turned it off and back on again but all I get is the fan - no boot chime. I'm getting 5.0V at the external floppy port, so I'm assuming this is an analog board issue. The Dead Mac Scrolls confirms this, and I've tested the barrel rectifier at CR2 and the transistor at Q2 which seem good. It looks like the next step is replacing the flyback transformer. Should I do this or replace the capacitors on the analog board next? If I need a flyback where can I get one? Thanks in advance!

    Another way to transfer programs to a classic Mac

    Click on the Guru Modem link in the original post, where you will find multiple places to buy it including eBay.

    The Definitive Guide to Connecting your SE/30

    There's also the Guru Modem to FTP files to your SE/30 or any classic Mac. See my posting here.
  15. Before I got an Ethernet card for my SE/30, I used the Guru Modem to transfer programs onto it. I haven't seen any postings about it in here, and it should work with any of the classic Macs. What's slick about this wireless internet modem is that it allows you to FTP to sites like Macintosh Garden or your modern computer running an FTP server (I used the app FTP Server on my MacBook Pro), store your downloads on its microSD card, then you download it to your classic Mac via xmodem or zmodem with a terminal program like ZTerm. The only painful part is that the ftp is command line, so it's easy to have a typo. And you can telnet to BBS's like Captain's Quarters too! The Guru Modem goes for $70 + $6.82 shipping.
