    Check ALL of the capacitors, even the tiny ones buried down under things. If the entire secondary side of the supply went away, it's most certainly something wrong with the primary side.

    Found the problem, the PLCC socket the ASIC resides in had bad solder joints. I was going crazy tracing out the board since there's not really that much between the memory slots and the 68000, just a...

    IDE/ATA is basically the ISA bus with some buffers. Early disk controllers had little in the way of fault detection and misbehaving hard drives could and did often take down the whole machine. Though...

    The plastic base is more of a pin carrier than structural support, as you've found out breaking a pin off. Most of the structural support comes from being soldered to a PCB.

    The "breakable" pin...

    Well after a year working on the board on and off, I got it to boot reliably and the garbage on the screen went away. The problem? One of the caps was an incorrect value, unbelievable that a single...

    I'd assume it'd be like any other hard drive, the less you use it, the longer it'll last.

    If 30+ year old SCSI/MFM/RLL/ESDI/IDE hard drives are anything to go by, I'm sure that a good number of...

    The large caches are needed for the SMR housekeeping itself, it doesn't help at all with backed up I/O requests from the disk controller. To buffer even a couple of seconds of I/O from the host...

    The first "brrrrt" is the protected mode floppy driver loading. The subsequent "chuk chuk chuk" sound is Windows trying to find a file on the drive. This can be verified when you insert the floppy...

    SMR drives cause any RAID setup to fail.

    RAID controllers have no concept of what SMR is, and when a drive starts doing SMR housekeeping, the RAID controller falls flat on its face because the...

    The memory test that Macs do is very basic, bad memory can easily get past it, especially at higher address ranges. I have had plenty of problems with bad memory on Macs not being found by the Mac...

    If two different system installs are behaving the same, I'd say there's a fault with the machine. You may have bad RAM, which is an unfortunately common problem on these old machines.

    Not sure off hand, but they're usually pretty standardized sizes. I don't keep many X2 capacitors around because they don't go bad that often, and I don't usually repair power supplies old enough to...

    220, 330, 470 and 680nF X2 capacitors are common, as are larger 1 and 2uF types.

    But those aren't the only types of caps that can fail, electrolytics fail as well and you really can't have enough...

    You need to upgrade that CPU, it's painfully slow. The D630 will take up to a T9500 and have a massive performance boost.

    Most AT style motherboards will line up with slots on the back of the case, the problem is the standoffs. You'll probably have to end up marking, drilling and tapping more mounting holes for large...
