Adam74: A terminal for a small 8-bit computer
Something that struck me reading about the history of the Apple I computer was the fairly simple “ASCII bus” that it used for input and output. As I understand it a hobbyist back in the day could get an ASCII keyboard that quite literally presented as an interface a header giving 7-bits of ASCII and an additional…

RISC-V is getting MSIs
Message signaled interrupts or MSIs describe a way to signal an interrupt without a dedicated interrupt request pin (IRQ). One of the most prevalent uses for MSIs is the PCI bus, and the PCI specification defines the MSI and MSI-X standards. The potential benefits may include: (1) reduced number of direct wires from…

The Talos II, Blackbird POWER9 systems support tagged memory
Nowadays, there is increasing interest in adding tagged memory functionality to CPU architectures. Such architectures associate one or more tag bits with each quantum of a system's memory. There are many motivations for this ability to associate “metadata” with individual memory words, but one of the most clear is the…

Computers Built to Last
I've recently thought a lot about the essay The computer built to last 50 years by Ploum. It's a delightful piece about the author's ideal, long-lasting computational platform - precisely the thing I enjoy reading. It's got a nice blend of slow tech and libre computing advocacy mixed with personal ponderings centered…

Modernizing my 1980s sound system
Where the last two posts were primarily about software ( Navidrome and beets , respectively), this post will be more about hardware (and a bit of software to control it). Hopefully it’ll be useful to others with older sound hardware, especially those who are compelled (as I am) to avoid buying a “connected” device…

Italian CPU – The Genesys B52 MMX
On this site you can read about thousands of processors models. And every year it is more and more difficult to write about some new (old) processors, since everything has been known for a long time. But there are also exceptions to the rule which we love to find. In 2021, I learned about one unusual processor, the…

What's the risk from fake Yubikeys?
I found this on a security-related Slack (shared with permission). It launched an entertaining discussion about the risks of taking a potentially fake FIDO token. We all know the risks of taking a free USB drive and shoving it in our computer, right? USB sticks can install software, act as a keylogger, transmit data…

Building a fast all-SSD NAS on a budget
I edit videos non-stop nowadays. In a former life, I had a 2 TB backup volume and that stored my entire digital life—all my photos, family video clips, and every bit of code and text I'd ever written. Video is a different beast, entirely. Every minute of 4K ProRes LT footage (which is a very lightweight format…

Pine64’s response to “Why I left Pine64”
We rarely, if ever, make responses to blog posts or articles. In fact, there is only one instance that I can think of when we did so. So then, somewhat uncharacteristically, this is a response post to Martijn Braam’s blog in which he explains why he left the PINE64 community. Let’s get one thing out of the way first…
