  1. 6502workshop.com is joining forces with Captain's Quarters BBS for a new contest where the winners will star in Nox Archaist!  Captain's Quarters is one of the few remaining Apple II BBS's and runs on a real Apple IIgs.  The top four finishers of the BBS's Masters of Trivia game will get to name a NPC (non-player character) in the Captain's Quarters pub, which will be located in a pirate town of the upcoming RPG!  The NPC's will be pub patrons, so who wants to be a virtual barfly?!

     

    Trivia categories include Nox Archaist, Computers, Star Trek, Star Wars, Sci-Fi & Fantasy, Big Bang Theory, 80's Pop Culture, and many more.  The game will begin with the next round of trivia soon so sign on now and join the realm!

    I would say you might hav me a trace with intermittent contact somewhere on the logicboard.

    Had this happen before and it was a pain to find it because it would measure just fine on the first two times checking every trace in the video section. There was a break right where a trace connected to one of the solder pad of one of the video address muxers.

     

    A hissing sound might indicate that the board isn’t outputting a correct sync (probably hsync) signal. I think this can happen if you got an issue with one of the binary counters UF8 and UG8.

    I once accidentally shorted two pins on one of the counters while measuring some stuff and this made the video drop out while the analog board emitted some unpleasant noise.

     

    Can you get a high res picture of your logicboard? If you’re lucky we can see something.

    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:

  3. 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.

  4. 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...


  5. 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?


  6. 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...


  7. 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!


  8. 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.

    How about adding a zip 100 and a Syquest 44 to the mix, he he.  

    I had a zip 100 back in the day, but it always hacked me off that those disks were so expensive.  The zip drives were available for how many years and those damn disks never seemed to come down in price, I imagine because no one else besides Iomega was allowed to produce the disks.

    Via FTP yeah?

     

    I can connect via FTP at 7.1 which is good enough.

    No, I'm talking via AFP - my SE/30 running OS 7.5.5 can connect to the Pi file server.  I haven't tried to connect to it with any earlier OS versions...

    Nice... What is the oldest system that you're able to connect to it?

    I can connect up to it with my SE/30 running OS 7.5.  I haven't tried OS 7 yet.

     

    What's cool is that I already use this Pi to run TCPser in order to emulate a Hayes modem for my BBS, and it was just sitting there idle most of the time anyway...

     

    I installed A2Server which contains Netatalk v2.2.4.


  12. Two users so far - woohoo! :lol:

     

    I accidentally found out that my MacBook Pro running OS X 10.12.6 can transfer files to and from the server - the server just showed up in Finder one day and I clicked "Connect".  I assumed that modern Macs wouldn't be able to connect to older versions of Netatalk.  This is another nice way to get files from my modern Mac to my old Macs (ftp is what I was using before this).

  13. Hey guys,

     

    I've been playing around with Netatalk on my Raspberry Pi and have a classic Mac server up and running over the net!  It's kinda like a next-gen AE Line for all you old Apple II users out there...

     

    The server mostly has B&W Mac games on there now, but I'll be adding lots more compact Mac stuff in the future.

     

    Point your Chooser towards classicmac.ddns.net

     

    Name: p*i*

    Password: c*a*p*t*a*i*n

     

    Remove the asterisks when you actually sign on...

     

    For OS 7.5 - OS X 10.4.  You'll need the latest versions of AppleShare and OpenTransport available here to connect.  My SE/30 with Ethernet card connects up flawlessly.

     

    Hope to see you there!  Leave a SimpleText message if you do get on.
