    Reinstall System 7 from scratch

    There’s no speaker connector on the classic II, just like the Plus it’s integrated in the main LB connector. Is sound working after boot up? You can check this with a system 6.0.8L (make sure there’s an L!) boot disk by navigating to the sounds control panel and adjusting the volume from there. I’m not sure system 7 lets you do that from an install floppy. If you don’t get anything from the built-in speaker, try the headphone jack. Also, you could ask the person who recapped it if sound was working on their end... could be an analog board issue... For the hard drive, I suggest creating a system 7 disk tools disk and a lido 7.5.6 disk. Lido is great for formatting or diagnosing if there’s an issue with the scsi bus or not. It won’t test the whole thing but you should be able to see if the problem is logic board related or hard drive related.

    SE/30 can't recognize SCSI HDD

    Given that you've tested many known good units (correctly terminated I assume since you're using them with other macs), I'm afraid the problem must be coming from the SE/30 board. Can you please post pictures of the top and bottom area around the SCSI chip?
  3. What LaPorta said, plus the following: - Have a high wattage iron on hand (50W+). Optional but very desirable (Oh I wish I had brought mine with me!): Desoldering Station. - It's particularly difficult to remove the big snap on capacitors. There's apparently only two on the 660. The 900/950 have four. - Be patient. Cold joints can happen very easily. - Have the correct solder type. All my joints look frosted. They're functional but it's never too good. I don't know what the blend was in the 90s. I think I have 60/40 and that wasn't it. - Don't rely on preexisting lists (I learned that the hard way when I ordered caps for Armoralley's TDK LC PSUs). Have a pen, paper and ruler ready and make your own list. - Good luck. Don't feel scared of breaking it. The Delta PSU in the 900/950 is really a pain to work on (soldered on daughterboard and epoxyed on caps.) I've never seen anything like it. Back the the current matter: I have no idea how the original Soft Power circuitry works. Is it on the power supply or is it on the logic board? I'd say the latter so theoretically the key mechanism is handled by the LB, right? So the signal goes from the key to the LB and the white wire just carries the information given by the logic board to the PSU? The transistor added for the ATX mod is only there to 'convert' the signal (i.e. ground it) for the ATX PSU to interpret it correctly, right?
  4. Thanks Gorgonops! Sit rep: Finishing the recap and redoing/cleaning all the solder joints didn't fix it. It's arcing now (for a brisk moment when it gets connected to mains power), so I'm nervous every time I'm near it when it's plugged in. This cannot go on, I've invested too much time on this PSU. So I've decided to tackle this repair by swapping the innards with that of an ATX power supply using @GeekDot's guide. That way it'll never break down again. I have a couple of questions before I 'pull the plug' on this PSU. Perhaps @GeekDot is better placed to answer these? - Is the key mechanism fully working with your small Soft Power circuit? (i.e. 'off' is off, 'on' is soft power and 'locked' is auto power on with the keyboard/mouse input disabled) - Did you have time to create a molex adapter board? I honestly can live without them (SCSI2SD is bus powered), but it'd be nice to have a fully working PSU. In case you haven't, I'll start working on one after it the Quadra gets fixed. I'm thinking about getting a Corsair VX450, but it only has 3 Molex plugs. Are there any modern PSUs with 4? Thanks in advance for your help!

    Powermac G5 no SATA

    Is this a Powermac G5 or a Mac Pro? 1,1 and the speed rating would indicate first gen Mac Pro with INTEL processors. If so it has pcie slots, not pci. Either way, mac sata controller cards are available, for intel or ppc. But please confirm your exact model before buying anything...

    Congrats! I can imagine how happy you must have been when you saw it post!

    Apple IIc Monitor Power Cord

    Here it is:

    The RCA video cable is platinum grey, and the connector housing ressembles that of the Mac Portable’s low power mouse.

    @BL! What version of HD SC Setup are you using? I've never heard of this glitch. I know it's supposed to work just fine.

    RAM required for DOS card

    I've even heard reports saying that 64mb SIMMs work. But getting a 32mb FPM is the recommended route. Plus, I don't know if that much RAM is even that useful in a 66MHz DX2 machine...

    Reinstall System 7 from scratch

    That’s a typo in the guide... This is what I used to set up a scsi2sd hard drive emulator. I wrote a 1gb image to an sd card using this tutorial. Writing a 1.44mb image to a floppy is the same process. Be careful to get select the correct drive identifier or you might wipe your hard drive!

    Reinstall System 7 from scratch

    Welcome to the club. With what you have on hand, you should be able to write to floppies without a problem. But here's a few tips to kick things off... General maintenance: - Capacitors on the logic board. They need replacing. Absence of sound is a typical symptom. You'll have to replace them or have someone replace them sooner or later. If not, it will quit working altogether in a few months/years. - Battery. Those can leak and destroy the board. When you get it recapped, remove the battery or replace it. It's just there to keep track of time and a few parameters like 32 bit addressing, mouse and double click speed etc. - Hard drive. They are now more than 25 years old and some of them are just dead. If yours can't boot, it might be a goner... With the 'bad news' out of the way, where's what to do: - Get a set of floppy images from macintoshgarden.org, macintoshrepository.org, or the Mac GUI. 7.1 should be plenty fast on the Classic II. 7.5 has more features but might be slower. - using macOS, you can write to floppy disks using the dd command. from savagetaylor.com (but edited) With that done, try to boot the mac with the first floppy. It should be labeled Disk Tools or Install me first. Try to reformat the hard drive using Apple HD SC Setup. If it succeeds, proceed with the install, and follow the instructions. Good luck!

    Fitting a SCSI2SD in a 68k Mac

    Apple HD SC Setup expects a certain number of characters when it reads the drive’s firmware. If a space was missing no wonder it didn’t show up. Lido or Silverlining will set up the drive correctly no matter the firmware.

    So you have the correct settings and it still doesn't show up? Have you tried another utility like Lido?

    Fitting a SCSI2SD in a 68k Mac

    @BL! 1/ Is the device terminated? Check the box on the 'general' tab of scsi2sd-util 2/ If you're using the unpatched version of HD SC Setup, you can only format drives that have the apple firmware. How did you configure the vendor and product IDs on your SCSI2SD? From the OP:
