    Help with my Macintosh Classic

    Yes, shouldn't the computer boot from ROM, even if floppy and HDD are disconnected? I think so...

    Can't set year 2020

    I will try this. SetDate crash the computer half of the times I use it.

    Radius Pivot SE/30 color monitor requirements?

    Ah, thought the "256K" on the ROM was referring to the VRAM, but maybe that's just the ROM size. So are these the VRAM slots?

    Radius Pivot SE/30 color monitor requirements?

    Maybe I just don't have enough VRAM for more than 2-bit? That's annoying... Edit: should be enough for 16 colors, right?

    Radius Pivot SE/30 color monitor requirements?

    Oops, I prepared a picture, but forgot to attach it: I don't have the Mac running at the moment, but where do I set the ColorSync profile?
  6. Hi, what kind of monitor do I need to display color with the Radius Pivot SE/30 card? Currently I have an Apple Performa Plus Display (model M9102Z/D) hooked up, and it can only show 2-bit greyscale. The monitor is capable of 16-bit color, but apparently not with this card. I understand from other threads that special software is not needed. I installed RadiusWare which gave some extra features to the system, but didn't affect the color depth. I know the Performa Display is kind of low budget, and my guess is I need something more fancy.

    Apple Color Plus 14" Display - Switch Problem

    My solution for a broken switch

    Help with SE/30

    I went ahead and swapped the logic board, floppy and HDD over to my other SE/30, and now the display is very bright and nice. I also did some extra scrubbing with IPA and a cotton swab around the sound components, and sound is also back. So until the next thing breaks, I almost consider this Mac finished. One new issue though... It won't accept RAM SIMMs on Bank B. As soon as I populate Bank B, chimes of death at startup. I've tried several SIMM combinations (all 1 MB SIMMs), always the same issue. Four of them are confirmed to work in my Classic, but they won't work in the SE/30. Should I continue look for bad traces, or can it be a specific component that is known to fail, causing this issue? Then some future things I need to fix: - re-cap the AB - adjust the CRT yoke, the display is somewhat tilted

    I vaguely remembered this, but then I couldn't find any information about it. Thanks!

    Can't set year 2020

    Just wiped the HDD and installed System 7.1, and for some reason I can't set the year to 2020? Up til 2019 is fine, then it skips back to 1920. Anyone knows what that's about? I don't have a battery installed at the moment. I can't recall that I've had this issue on my other Macs.

    Help with SE/30

    I think I'll try and move the HDD/floppy/logic board to my other SE/30. I think/hope the screen/analog board/PSU are in better condition on that one. That way the analog board re-cap can be a future project. Just need to clean up some rust first...

    Help with SE/30

    I think the drive somehow corrupted all the disks I inserted. The replacement drive works fine now, but I had to re-format the disks. Other disks that I never tried in the faulty drive works fine. But the drives definitely needs a good clean anyway, so I'll bookmark the video, thanks!

    Help with SE/30

    I guess going over the analog board and PSU is inevitable. Another issue now is that the floppy doesn't work anymore. It worked when I got the Mac, and it mounted the first floppy I inserted today, but started to behave weird when it was ejected. Now it can't read any disks. I just replaced the floppy drive with one from a Classic (unknown condition), but it acts exactly the same with the replacement drive. But at least I just got to practice to discharge the CRT... Edit: Actually it reads and formats some disks just fine. So need to give that some more time...

    Help with SE/30

    We have major a breakthrough! So I replaced UJ2, UJ3, UJ4, let the board soak in vinegar for a couple of hours, rinsed it in soapy water and then let it dry over the evening and night. When I just powered it on there was a normal chime (not as loud as the chimes of death I had a week ago), but still the same horizontal bars. I restarted it a few times and sound was gone again, and horizontal bars every time. Then I remembered that I forgot to put the video ROM back after cleaning... Now: So the two obvious issues right now: - sound. Only twice have I heard the startup chime, otherwise sound is dead. Also on the headphone jack. - the display has issues. It's very dark, and I don't know if you can see it on the picture, but there's some lighter "shadowing" to the right of black pixels. Any advice where to start troubleshoot these issues? I can try to adjust the brightness trim pot on the analog board, I just need to get a proper tool first. I guess the analog board needs a re-cap too... I'm not just that comfortable yet with CRT discharging and handling the high voltage side of things.

    Oh, I didn't know that. I went ahead and changed UJ4 and UJ2 too, but I left the UI chips because they didn't look to bad. I guess I should've change them all when I was on to it... I also understand now that it was a mistake to take the replacements from my other (damaged) LB without knowing their status. They just looked to be in good condition... The LB is in another bath right now, it was so full of flux residue and other gunk, it needed a good rinse. We'll see how it works when it's dry again, but my hopes are not so high (anymore).
