    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?
