So long, Opportunity rover

(TenFourFox Development - 14.02.2019, 02:38) It's time to say goodbye to another PowerPC in space, this time the Opportunity rover, also known as the Mars Exploration Rover B (or MER-1). Finally declared at end of mission today after 5,352 Mars solar days when NASA couldn't re-establish contact, it had been apparently knocked off-line by a dust storm and was unable to restart. Originally intended for a 90 Mars solar day mission, its mission became almost 60 times longer than anticipated and it traveled nearly 30 miles on the surface in total. Spirit, or MER-2, its sister unit, had previously reached end of mission in 2010. Both Opportunity and Spirit were powered by the 20MHz BAE RAD6000, a radiation-hardened version of the original IBM POWER1 RISC Single Chip CPU and the indirect ancestor of the PowerPC 601. Many PowerPC-based spacecra

The last POWER1 on Mars is dead

(Talospace - 14.02.2019, 02:33) The Opportunity Rover, also known as the Mars Exploration Rover B (or MER-1), has finally been declared at end of mission today after 5,352 Mars solar days when NASA was not successfully able to re-establish contact. It had been apparently knocked off-line by a dust storm and was unable to restart either due to power loss or some other catastrophic failure. Originally intended for a 90 Mars solar day mission, its mission became almost 60 times longer than anticipated and it traveled nearly 30 miles on the surface in total. Spirit, or MER-2, its sister unit, had previously reached end of mission in 2010. And why would we report that here? Because Opportunity and Spirit were both in fact powered by the POWER1, or more accurately a 20MHz BAE RAD6000, a radiation-hardened version of the original

The AMD POWER7?

(Talospace - 11.02.2019, 02:13) On a recent Hacker News discussion someone pointed me to this weird historical oddity: the AMD Opteron-socket-compatible POWER7 as reported in El Reg, circa 2006. We use a POWER6 here at Floodgap for the main server, which as typical for RISC servers of those days uses a bespoke logic board and getting a replacement for it was quite expensive (as we found out when it blew one in 2014). Part of this was no doubt due to their low production volumes and in 2006 IBM was still producing x86 Xeon-based servers, so it made logical sense to try to consolidate their manufacturing. (Recall Apple did something similar with the Power Macintosh 4400 and the "Yellowknife"-derived "Gossamer" beige Power Macintosh G3, both of which were intended to use, or at least use more, off-the-shelf commodity PC components.)

However, with all the work […]

So long, Itanium

(Talospace - 02.02.2019, 19:02) I have mixed feelings about Intel announcing the end of Itanic the Itanium. Everyone knew this was coming, of course, but Intel finally officially gave Itanium a death date of mid-2021 instead of keeping it limping along as it has for the past several years. On the one hand, I don't like Itanium for killing PA-RISC. The first machine I ever had root on was a HP K250 running HP-UX 10.20, and I still have a PA-RISC laptop (an RDI PrecisionBook C160L) and a C8000 with dual PA-8900s, the most powerful Precision Architecture workstation HP ever made. I thought PA-RISC was a nice, clean instruction set with decent performance and HP seemed to at least try to keep up with PowerPC and SPARC, and I think it died before its time (there was even talk of using PA-RISC in Amiga computers!). HP is still the Itanium's only cus

XAMPP for PowerPC

(G5 Center - 02.02.2019, 04:20) If you are at all interested in hosting a simple (or complex) website or doing some experimentation from your older Mac, I do recommend grabbing the incredibly useful XAMPP to make the process a little easier. XAMPP is kind of a self-contained install of the Apache httpd server with PHP and CGI turned on, a MYSQL server, an FTP server, and some other tools and documentation. It's cool, because it comes with a little tiny app that lets you turn off the services as you see fit. You can run it when you want to try out different configurations or different websites. For Leopard, the basic Apache httpd server isn't that older than the last available XAMPP package for G5 machines. My base Leopard httpd server is 2.2.7 while the one included in the XAMPP package is 2.2.14. Still, that includes some bug fixes as well as newer versions of PHP and MySQL. If you are going to run old software, might as well run the last version of it you can find. Note: I do believe, using MacPort

Happy New Year - Broken Links

(G5 Center - 01.02.2019, 03:30) Happy New Year, fellow G5 fans! Sadly, as I look over this site, I admit that many links are now non-functional. The information here is generally still fine, but you will have to search around for working links to the apps I recommend. Some developers have likely removed older apps, even though it is handy for users of old PowerPC machines. There are some app alternative websites too, including at websites like PowerPC Software Archive. Open source apps are just a great resource in times like these, as they tend to have ready archives available for users trying to maintain ancient machines. So, hang tight. I'll be fixing links, removing some outdated software, and seeing what the future is for this website. -- Nathan

Alpine Linux 3.9.0 available

(Talospace - 30.01.2019, 15:44) Alpine Linux 3.9.0 is now available. Unfortunately for platforms that aren't x86_64, Rust is not available and therefore packages downstream of it (most notoriously current versions of Firefox) are not available either. That includes their ppc64le support, which doesn't seem to support the POWER9 yet, though there is hope for Talos II support in a future release. Alpine Linux's less typical internal configuration seems to be the sticky point. There had been requests to help with the Rust porting effort back in October, and while the ppc64 version could build, it apparently had (has

Firefox 65 keeps up the POWER

(Talospace - 30.01.2019, 07:02) Firefox 65, thanks to the continued heroic efforts of the Talos and Power ISA community, finally builds out of the box on this Fedora 29 little-endian Talos II without any patches. The marquee feature in this release is WebP support (as demonstrated in Google's WebP gallery). As always, make sure your Rust and C compilers are up to date, and you will probably need to update cbindgen in cargo. Among other bugs swatted, this version of Firefox fixes issues with jemalloc on systems that use a 64K page size (most though not all Linux distros currently supporting ppc64(le), including Fedora 29 which I'm typing in), so ac_add_options --disable-jemalloc should no longer be necessary in your .mozconfig. Firefox 66 is currently not buildable due to bug 1521713

Flicker fixin' the WX7100

(Talospace - 26.01.2019, 21:10) We talked about properly enabling the Command key so that Power Mac users could feel at home, so let's talk about flicker fixing so that Amiga users will feel at home. ;) A gaming pet peeve of mine on modern systems is that full screen is still often the default. This is a workstation, damn it, not a freaking DOS box. There are other things running! But while working on a forthcoming article about Linux gaming on the Talos II (spoiler alert: it's a thing), my pet peeve was compounded upon returning to my usual display resolution when the AMD WX7100 workstation card started randomly flickering. The first time this happened I solved it with a power cycle, but obviously I don't want to do this every time if I accidentally start a game with the wrong options. Apparently this regression in amdgpu was introduced

TenFourFox FPR12 available

(TenFourFox Development - 26.01.2019, 08:19) TenFourFox Feature Parity Release 12 final is now available for testing (downloads, hashes, release notes). There are no additional changes except for one outstanding security update and to refresh the certificate and TLD stores. As usual it will go live Monday evening Pacific time assuming no difficulties. For "lucky" FPR13 I want to take a whack at solving issue 541, since my ability to work on Github from the G5 is seriously impaired at the moment (I have to resort to various workarounds or do tasks from the Talos II with regular Firefox). Since this has some substantial regression risk it will probably be the only JavaScript change I do for that release pending further feasibility tests on

Introducing appmodmap: make the Command key work again (or, making Mac refugees into Talos owners)

(Talospace - 22.01.2019, 06:00) At least in terms of sheer numbers, Power Macintoshes are still the most common Power ISA-based computers, and those of us who still used Power Macs until lately (while my trusty 13-year-old Quad G5 may no longer be my daily driver, it is still used, and it's still under my desk) may well be the Talos II's most natural audience: we gravitate to non-x86 architectures, we like PowerPC in particular, and many Power Macs nowadays run Linux too.

Do things really end?

(viva PowerPC blog - 16.01.2019, 12:16) Two years ago, in my last post on this very blog, I said, that my brief PC journey ends and I'm back on PowerMac. How did it end up? Okay, I tell you the bad news right now: I'm publishing this from a Core i5 based HP EliteBook, which is at the moment my main computer. The G5 wasn't used to do anything useful at least for six months, in fact it's collecting dust in a shelf.  But don't stop reading here, let's  go back to January 2017 for an explanation... Back then I really moved back to PowerMac G5. I sold the HP desktop I had since December 2015, moved all data created on it to the G5 and simply started to use it daily as if I never left.As I mentioned in previous post, even before the move back to the G5, I replaced the failing Radeon 9800 (flashed PC version) with perfectly good Radeon 9650 (Mac version).  The 9800 served me well for over eight years, but one day it displayed only weird artiefacts on the screen and it was over.

Something for the weekend: Classic MacOS Lua

(TenFourFox Development - 01.12.2018, 00:50) First, a TenFourFox FPR11 update: the release is delayed until December 10-ish to coincide with the updated release date of Firefox 66/60.4 ESR. Unfortunately due to my absence over the holidays this leaves very little development time for FPR12 in December, so the beta is not likely to emerge until mid-January. Issue 533 ("this is undefined") is still my biggest priority because of the large number of sites still using the tainted version of Uglify-ES, but I still have no solution figured out yet, and the 15-minutes-or-longer build time to reconstruct test changes in JavaScript if I touch any headers seriously slows debugging. If you've had issues with making new shipments in United Parcel Service's on-line shipping application, or getting into your Citibank account, this is that bug. So in the meantime, since we're all classic Mac users here, try out MacLua, a new port

And now for something completely different: SCSI2SD is not a panacea

(TenFourFox Development - 15.11.2018, 22:51) When well-meaning but underinformed folks hear you keep old Macs alive, without fail they tell you to replace the capacitors, and install a SCSI2SD. The first bit of "advice" drives me up the wall because while it's true for many Macs, it's now uttered in almost a knee-jerk fashion anywhere almost any vintage computer is mentioned (this kind of mindlessness infests pinball machine restoration as well). To be sure, in my experience 68030-based Macs and some of the surrounding years will almost invariably need a recap. All of my Color Classics, IIcis, IIsis and SE/30s eventually suffered capacitor failures and had to be refurbished, and if you have one of these machines that has not been recapped yet it's only a matter of time. But this is probably not true for many other systems. Many capacitors have finite lifetimes but good quality components can function for rather long peri
