    SE/30 video redraw problem

    That’s the weirdest thing I’ve heard of... Can you post pictures.

    "(Error #-199)" Error Code

    There’s a good bit of information in the first paragraph. https://en.m.wikipedia.org/wiki/Apple_Partition_Map

    "(Error #-199)" Error Code

    What computer are you using, and what, if any, modifications have been done? Have you tried to format the disk to < 2GB? Some ROMs don’t see more than 2GB correctly.

    Macintosh SE screen flickering/changing shape

    Sorry if I left you hanging..... J1 is the connector from the deflection coil on the CRT to the analog board. There are 4 wires, I think I remember that they’ll be red, blue, green, yellow. I don’t remember the order. Check the solder joints on the analog board at that connector, and check the connector for brown / black, that will come from inside the connector. If there is brown / black, conditions will only get worse. Change the connector. https://www.digikey.com/product-detail/en/0015311046/WM1042-ND/313615/?itemSeq=287242932 https://www.digikey.com/product-detail/en/0019091049/WM1606-ND/26362/?itemSeq=287243257 https://www.digikey.com/product-detail/en/02-09-5106/WM6388-ND/252899/?itemSeq=287243638

    Looks like the typical J1 solder joints.. Repair those, and go over the rest of the analog board.

    Lamp built from an AirPort

    Really cool! But I hope that wasn’t the A1075 PoE. I’m looking for one of those.. Do ya have a pic of the bottom side?
  7. I’m gonna recommend the link above I posted from UniServer. See if that works out for you, gets you on a good path. Theres a lot of learning in there.
  8. The screw is either a #6 or #8, with 32 TPI. From what I remember, it’s an 8. Take it to a hardware store and ask for one in that size that’s stainless. It’ll cost less than $1 The computer was probably just stored someplace that was humid, moist, or damp.

    Classic II Color Video Out

    When I first read the heading, I was hoping that you were going to say that you came up with an idea that the rest of us with Classic IIs could create / duplicate. Fooled again! Oh well. I need to finish working on the voltage issues with my Classic II first.....

    iMac G4 won't eject CD/DVD drive!

    You can also try holding the mouse button at time of boot, and that should eject the disk.

How did you get the replacement 2N3904 so quick? Just wondering, since you replied only 16 hours after my post. I wish I was that quick!
  13. It looks like replace 2N3904 let us know if that works out for you.

    SE/30 repair (and a little problem).

    It doesn’t matter what’s on the HD when you boot from a floppy.. When you insert a floppy at time of boot, the machine looks for a valid system on the floppy disk. If it finds one, it will continue to boot from that floppy disk. If there’s not a valid system, it will eject the disk, and look to SCSI bus, starting at ID 0.

    You might have a too early version of Mac OS. Do you know which one is on the floppy?

    Classic II weird issues after analogue board recap

    I agree with bibilit. Run a meter while running the machine. And try to keep them next to each other, so you can keep an eye on both at the same time.. As far as what component(s) are (might) be at fault..... You’ll need more professional help than me.. Sorry. I have my own Classic II problems that I don’t have time & money for. edit: So... Wait... What.. Why did you change one of the diodes? Was it destroyed? Are there bigger problems?

    Connecting a ZIP drive to a Macintosh Plus

    Ok first try a REAL SCSI cable, not one of those printer cables for Microsoft computers.. If that doesn’t work, try a different Zip drive. Its got to be one of those problems. The only other thing I can think of.... Is the Zip drive plugged into a zip PSU (5V 1A, Neg Gnd), and does the light turn on when first powered up? Are there any indications that the Zip drive has power?

    Does anyone know about the weird SE fan?

    The proper term is “centrifugal fan” or “blower”, commonly used in ventilation systems.

    J1 connector (Plus analog board)

    I found all the jack pieces here https://www.digikey.com/product-detail/en/0015311046/WM1042-ND/313615/?itemSeq=287242932 https://www.digikey.com/product-detail/en/0019091049/WM1606-ND/26362/?itemSeq=287243257 https://www.digikey.com/product-detail/en/02-09-5106/WM6388-ND/252899/?itemSeq=287243638

    Aeroflex SCSI to USB adaptor?

    I wonder if it’d work on 68k? If it’s for a ppc Mac, I’d use a pci usb card. Would 68k even be able to format a Flash Drive? It doesn’t seem to be made to use USB to attach a SCSI device.

    SE FDHD Restoration

    Thank you for doing that! What about the male connector? Got links? A lot of people talk about fixing / repairing their machines, a lot of people help them, a lot of people question........... ..... And then that person comes back with “I found it at “parts supply” & fixed it, Hey thanks!” But never give information on the part, or replacement part.... Yeah, we can all look at “parts supply” .com, but xxxx, don’t tell me “I found it at “part supply .com”! Give us a link, or more information about it.. Damn, looking up parts, even in the age of internet, can take days (and many brain cells). Thank You! I wish more people would give exact part #s.. I’ve thrown exact part #s at people many times, and I love it when they say “ Thanks, it’s working again”.
