I went kind of overboard looking into issues with Altera USB Blaster clones a couple of years ago. While writing that post, I ran into some really frustrating intermittent problems in Linux with jtagd that I was never able to figure out: I also experienced a really weird unrelated problem in Quartus Programmer 18.1 in […]

Last year, I bought a Macintosh Performa 410 on eBay. I wasn’t expecting it to be special in any way. The main reason I was interested in it was because I suspected it would have originally come with System 7.1P3, which was a weird Performa-specific OS version that nobody had preserved at the time. If […]

Last year, I repaired an NZXT Signal 4K30 USB capture device that I bought on eBay for cheap. It was completely dead, and the cause turned out to be a bad solder joint on an inductor, which prevented power from getting to a crucial part of the board. After I fixed it, I tried using […]

I’m no stranger to pushing hardware past its limits. For example, seven years ago, I tracked down an issue that prevented 16 GB of RAM being used in a motherboard that only supported 8. It ended up being a one-line GRUB hack to fix one of the ACPI tables that was mistakenly overlapping a PCI […]

Yesterday, for the first time in about a year, I tried powering on the Macintosh Performa 450 (LC III) from my past writeup about Apple’s backwards capacitor. It didn’t work. The screen was black, it played the startup sound, and then immediately followed up with the “Chimes of Death”. Nothing else happened from that point […]

This post is about the original OMAP3530 BeagleBoard from 2008. Yes, the one so old that it doesn’t even show up in the board list on BeagleBoard.org anymore. The BeagleBoard, not the BeagleBone. During my Chumby 8 kernel escapades, at one point I ran into a UART bug that affected multiple drivers, including the omap-serial […]

Earlier this year, I wrote about how I rescued a special recovery partition from an old Macintosh Performa 550’s dead hard drive. This partition had been lost to time and it was a race to try to save it before the remaining Performa 550 machines out there with their original hard drives were reformatted or […]

I was recently poking around inside the original Power Macintosh G3’s ROM and accidentally discovered an easter egg that nobody has documented until now. This story starts with me on a lazy Sunday using Hex Fiend in conjunction with Eric Harmon’s Mac ROM template (ROM Fiend) to look through the resources stored in the Power […]

I recently found myself needing to change the monitor that a cheap HDMI “dummy plug” pretended to be. It was a random one I had bought on Amazon several years ago that acted as a 4K monitor, and I needed it to be something simpler that didn’t support a 4K resolution. The story behind why […]

As part of my research into the Macintosh Performa 550’s factory recovery partition, I paid a lot of attention to eBay listings for these computers. I came to an interesting discovery that I had already suspected: big CRT-based Macs in this form factor are regularly damaged in shipping after being sold on eBay. Most vintage […]

I’ve been noticing a lot of fun stories lately about bugs in old software that suddenly showed up in newer Windows versions. For example, here’s an excellent writeup by Silent about a bug in Grand Theft Auto: San Andreas that laid dormant until Windows 11 24H2 came out. MattKC also recently posted a cool video […]

In my last post about hard drives that go bad over time, I hinted at having rescued a lost piece of obscure Apple software history from an old 160 MB Conner hard drive that had its head stuck in the parked position. This post is going to be all about it. It’s the tale of […]

As part of my work toward an upcoming post about a lost piece of very obscure Mac history that has finally been found, I’ve been playing around with old Apple-branded SCSI hard drives made by Quantum and Conner in the 1990s. What I’m about to describe is already common knowledge in the vintage computing world, […]

This is the story of how Apple made a mistake in the ROM of the Macintosh Classic II that probably should have prevented it from booting, but instead, miraculously, its Motorola MC68030 CPU accidentally prevented a crash and saved the day by executing an undefined instruction. I’ve been playing around with MAME a lot lately. […]
