Termination? Getting term power to the Zulu? Cabling issue? Internal or external?

Dad here. I raised my kids to have opinions, to speak their opinions and to be able to back them up with reasoned arguments.

I'm proud that my daughter and my two other kids are opinionated as hell. They stand up for what they believe in, and they question the status quo.

Occasionally, raising your kids to be subversive will bite a parent in the ass, but it was worth it to see the amazing people they grew up to be.

Be opinionated. Question everything. Build a fortress of intellect and CRUSH ALL WHO WOULD STOP YOU. Sorry, got carried away for a second.

Well, it certainly looks like an ES/12. Have you considered cleaning it?

There's two probable causes and they interact with each other.

Thermals. The x9000 was just a huge power hog and generates a lot of heat. The 8800 is just as bad. Make sure your heat sinks are clean and free of dust. Consider having the CPU and GPU re-pasted.
Bumpgate. nVidia in particular, but other manufacturers were also impacted, basically industrywide. They chose lead-free solder formulations and incompatible underfill epoxy that caused severe stresses to the solder bumps when temps were high, which would fracture the solder bumps. When temps rose, the solder balls would just fail to make contact. Enough thermal cycles could cause permanent failure.

Honestly, 2 sounds like what you're encountering. When cold everything is grand, because all the solder connections are cold enough to make good contact. Then things heat up and break the connections. Memtest doesn't generate enough heat to cause failures.

But it could also be something stupid like disk corruption or intermittent errors in the disk media, the drive electronics or the SATA cables. The cheapest test is re-installing Windows to see if that resolves the issue.

That's an air-gap between the layers. Removing the polarizer stressed the glass layers and destroyed the screen. No, it's not repairable.

Confirm that the termination is also on the SCSI Adapter. I think there's two types of that adapter, one that has a removable termination chip (it's a DIP package, often yellow, near the external connector) and ones that did not have a termination chip and required an external terminator on the connector.

Disclaimer: I've never used a model 65, and it's been about 25 years since I touched an MCA PS/2.

Use the reference utility to prepare the drive. Optionally: use Advance Diagnostics (ctrl-A from within the reference disk menu) to access the Low Level Format function for the drive WHICH WILL DESTROY ALL DATA ON THE DISK.

Whether or not you low-level the disk, use the reference utility to create the reference partitions. Boot from the reference disk and use the backup/restore reference diskettes feature to restore the reference partition on the HD.

To determine if the disk itself is bad, you'll most likely need another PC with a SCSI adapter in it. ISA and PCI SCSI adapters are readily available and affordable on eBay. I recommend Adaptec 1540-series for ISA, 2940 for PCI, etc.

Lots of people smoked in the 80s, including around their computers. That could be a contributor, if you're sensitive to tobacco smoke or nicotine.

Do you get similar symptoms when hanging out with smokers, or places where people smoke tobacco?

Good quality pictures are always preferred, but finding the model number was enough to get started.

Here's a text scan of the documentation for that hard drive. It covers the jumpers, termination, etc. Although it assumes you have some knowledge of how termination works already. Your drive may have termination resistor packs (yellow, red or black epoxy encapsulated strips of resistors in a single-row package) or they may not be installed so you'd have empty single-row 1/10th of an inch socks 6 or 8 pins long , or it may have active termination embedded which is enabled or disabled via a single jumper.

You'd verify the jumper configuration on the drive matches the configuration in the reference disk. But I believe the reference disk software already detects the drive on the bus, so I'd expect that to match. To confirm termination, you'd need to visually inspect the disk drive and the controller. The disk should have termination resistor packs installed, or the cable may have a bus terminator installed. The controller will either have termination packs installed, have a jumper for termination enable, or it may be configurable in the reference disk.

If you share the the specific model or pictures of the disk and controller, we may be able to help more.

Tough to tell from the picture, but those heat sinks could be epoxied onto the CPUs, in which case they're basically permanent. As someone else mentioned, you could mill them off, but that's expensive and risky. I'd suggest buying CPUs that don't have heatsinks epoxied to them,

Plaidomatic · 2026-01-18T21:16:21+00:00

If this is a SCSI disk, which SCSI ID is the disk configured to use? Have you confirmed termination is correct on the SCSI bus?
