Discord Weekly Summary — Week ending 2026-06-27

Another busy week across the channels — highlights include progress on the SHORK 486 Linux distro, deep dives into Mac II 68030 upgrades, an A/UX archival effort, and a big discussion sparked by Linux dropping AppleTalk support. Here's the rundown.


Summary

#the-lab-software
Admiral Shark has been preparing SHORK 486 for its first public release with ready-to-go builds. Highlights this week:
  • A new unified settings app, SHORKSET, with a menu-based interface, consolidating the various settings tools.
  • Plans for an easy disk-mounting interface and a basic network manager.
  • A new SHORK DISC variant — an ISO containing precompiled 486 and DISKETTE .imgs plus a guided install script that automates dd'ing an image onto a disk or diskette (handy for those without an IDE-to-USB adapter). Shark noted that for pre-El Torito 486s that can't boot the CD, you can still mount it via SHORK DISKETTE and run the installer.
Stinkerton18 built SHORK DISKETTE and booted it on a 486SLC, reporting two bits of feedback: config/build had to be run as root directly on their distro, and the full build failed on libXdmcp-1.1.5 with a 404 (fixed by updating to the xorg.freedesktop.org URL — Shark has since updated all the x.org URLs). The plan is to try building the DaynaPORT SCSI/Link driver module.

#the-lab-hardware
  • Cracking protected PAL/GAL chips: Xiang asked about unlocking protected AMD PALCE16V8H chips with blown security fuses. zigzagjoe and Bolle discussed the Chinese "RunFei" programmers, which appear to use power glitching (cutting power mid-erase so only the protection bit clears) for GALs, while SuperSVGA noted the PALCE method seems to apply VPP for a permanent unlock. Bolle confirmed it has worked on countless chips but has occasionally fully erased one in the process — a known risk with glitching. Bolle offered to share logic analyzer dumps.
  • Adding a PCI slot: Trina's Technobabble asked whether an unpopulated "PCI1" footprint on an ASUS F2A55-M board could be made functional by soldering on a slot. The consensus (bakkus, Dorkulon, Justin D. Morgan) was that it's possible but risky — bakkus estimated ~30% odds given unknown missing components — with cautionary tales of people soldering slots onto footprints that turned out not to be standard slots.
  • Aging HDDs: techknight shared photos of age-related head coil adhesive failure on a black 2.5" IBM drive, prompting a "Powerbook/iBook owners beware" thread and reminiscing about how painful HDD replacement is on white iBooks and PowerBook G3s.

#vintage-apple
The busiest channel this week (300+ messages):
  • Apple II Serial Grappler: Wavebird picked up an Apple II Serial Grappler card and sought documentation. Andy pointed to several archives and noted that since it (like the Apple Super Serial Card and AE Serial Pro) uses a 6551, those manuals should apply. Confirmed convention: slot 1 for printers, slot 2 for modems; back-panel connectors mount with #4-40 nuts.
  • Mac II 68030 upgrade deep-dive: An extensive technical discussion (DosFox, zigzagjoe, twvd, Bolle, Andy) on upgrading a Macintosh II from the 68020/HMMU to a 68030. Key takeaways: you need FDHD ROMs (the same ROM used in the IIx/IIcx/SE/30) as the original II ROMs go into a reboot loop with an '030; the IIx-style PAL is very simple and the rest is mostly jumpering PMMU socket signals; the AMMU is just a set of simple GALs (reproducible in three 16L8s per the prototype). Bolle is considering including an '030 adapter in a PowerCache/Turbo040 adapter for the Mac II. twvd clarified the ROM detects an MMU by running an instruction, so an '030 is detected fine. Andy also cleared up confusion over PAL SIMMs (a fix for larger SIMMs on the Mac II, not the IIfx's dual-port RAM).
  • 68851 PMMU hunt: Sharpie sought a Motorola 68851 PMMU for a friend's Mac II upgrade; Kai Robinson found one (expensive, but rare these days).
  • A/UX archival: Sharpie is archiving a full A/UX 1.1 set — 33 floppies (some needing extensive repair), manuals to be photocopied, and a QIC install tape. twvd floated the idea of building tape drive emulation into Snow so A/UX could be installed directly from such media. Sharpie noted an A/UX install tape may not have been archived before.
  • "Is it vintage yet?": A lively debate kicked off by the news that the next macOS is the last to support Intel. TopherPerson linked Apple's official Vintage/Obsolete list. Xodium argued early Intel Macs (pre-Nehalem) already qualify, while Dorkulon countered that old machines feel slow mainly because modern web browsers and apps (e.g., Discord) are so bloated.
  • Repairs & projects: Josh (new to the scene) posted a detailed Mac SE restoration troubleshooting thread — moisture damage, a ~30s delay before the cursor appears, and a BlueSCSI that reaches the data phase then times out. Suggestions covered the 5V rail (raised to 5.04V via the PSU pot, no change), bad SCSI controllers, termination/assembly issues, and rolling your own known-good disk image rather than trusting prebuilt ones. Still unresolved. Wavebird sorted out an Apple II joystick button issue — Apple wired the buttons to +5V rather than the conventional ground, unlike the IBM joystick they'd been testing with. Coal Shork is sourcing a 3D-printed inner bezel for a slot-loading iMac G3, prompting discussion of the structural challenges (the CRT effectively hangs from it, and 3D prints are weak along layer lines). For plastic polishing/scuff removal, Novus 1/2/3, Magic Eraser, and brake fluid were recommended (always test first). killvore recommended the Noctua A6x15 FLX as a drop-in 68040 fan.
  • KansasFest 2026: Ron's Computer Videos reminded folks that on-campus lodging registration closed midnight Friday June 26th. The event runs July 14–19 at the University of Illinois Springfield, with special guests Dan Kottke, Jimmy Mensch, and IIgs engineer Dan Hillman announced.

#the-lab-networking
The big story: Linux is dropping AppleTalk support (EOL in 7.2). nulleric shared the Phoronix article, kicking off a long discussion:
  • The source has been moved to the linux-netdev/mod-orphan repo, so the module can still be compiled and loaded out-of-tree. Andy already does this for his Synology NAS, and daniel confirmed building the out-of-tree AppleTalk module has been "remarkably painless" so far (DKMS can auto-rebuild on kernel upgrades, per Nick-el) — the main worry is future-proofing against kernel API changes.
  • Maighstir noted the removal is largely about the maintenance burden of low-quality (or potentially malicious) patches. The Linus commit message ("Let it join hamradio in our out of tree protocol graveyard") was described as "on brand."
  • daniel (Netatalk) framed Apple killing AFP and Linux dropping the kernel module as "a blessing in disguise" that opens up the design space for rewrites. They reported major progress on a userspace AFP client — at feature parity with Apple AFP in macOS 26, with ResourceFork and FinderInfo xattrs transferring correctly against both Netatalk and vintage Apple servers; only speed optimization remains. daniel also noted NetBSD will soon be the only living OS shipping DDP in the kernel out of the box (though thecloud pointed out it's commented out on some arches like evbarm and needs a recompile).
  • Other userspace efforts mentioned: the Netatalk client, and dev1098's pointer to TailTalk (a Rust/Tokio async userspace AppleTalk stack), which dev1098 has used to share files Windows → Farallon iPrint → LC II. daniel noted TailTalk's author chose not to make it interoperable with Netatalk's C API.
  • A reminder from thecloud and daniel that AppleTalk is more than filesharing — games, chat, printer drivers, etc. all build on DDP.
  • Earlier in the week, CTB troubleshot a missing AFPServer on a netatalk 4.2.3 install; daniel's common fixes: add appletalk = yes to afp.conf and start atalkd before netatalk.

#vintage-programming
1Bit Fever Dreams released cozyMIDI v0.1, a standard MIDI file player for classic Macs (runs fairly well on a Plus, very well on an SE/30). It plays type 0 and type 1 MIDI files, pre-calculates timing to avoid real-time divisions in the playback loop, and uses lean CopyBits animations. It needs a synth MIDI module (recommended: vintage Roland Sound Canvas SC-55ST and up, or modern mt32-pi). They initially used the modem port due to a printer-port issue, later traced to mistaking the modem-in port address for the printer-out port. Source is on GitHub (view as raw to avoid classic Mac line-ending issues).

#self-promotion
Plenty of streams and videos this week:
  • Ron's Computer Videos: a Let's Chat with Karl Baron (Kalleboo) on GlobalTalk, a 1989 Apple Desktop Media VHS feature, and a Let's Chat oral history of TNT Amusements with Todd Tuckey.
  • Trina's Technobabble: multiple streams — laptop testing, motherboard recapping/desoldering, and a Lenovo ThinkBook 15 G4 teardown.
  • BigBadBiologist: a two-part saga reballing and (improperly, with hot air) reattaching an Intel 440BX northbridge on an Acorp 6BX86 Pentium II board.
  • 1Bit Fever Dreams: a full video on coding the cozyMIDI MIDI file player for the Mac Plus.
  • HardwareHacker / Lord Heincrad: Let's Play streams of Subnautica 2 and Ni No Kuni.
  • seatsafetyswitch: a new blog post on an Apple IIgs pickup and RAM expansion.

Discord — Weekly Summary (Week of July 12, 2026)

Another busy week across the server, with a standout deep-dive into getting Apple's A/UX UNIX running (and archived), continued progress on the SHORK 486 Linux distro, and plenty of hardware repair adventures. Here's the rundown.


Summary

#the-lab-software
Admiral Shark made major progress on SHORK 486, a Linux distro for 486/586-era PCs. Highlights this week: forward-porting all the 7.1.x kernel patches to the new 7.2-rc kernel, including restoring build targets for 586 (K5, Cyrix 5x86), AMD Élan, IDT Winchip, RDC R-321x, UMC U5x, Geode GX1 framebuffer,and x87 math emulation. He also traced a kernel panic on Pentium Pro / Pentium II OverDrive to the SEP (SYSENTER/SYSEXIT) syscall path — the Pentium Pro reports the SEP CPUID flag but doesn't actually support the instructions — and added a no-vdso32 build option to fall back to int 0x80. He got mpg321 compiled and running (roughly 90% smooth on an emulated DX4 with a 320Kb/s MP3) and forked terminal-mines into "SHORKMINES."

There was also discussion about ML/LLM-assisted conversion of silicon die photos to schematics, which led to sharing Giulio Zausa's MMO-CHIP multiplayer chip reverse-engineering tool. DosFox reiterated the standing call for help reverse-engineering the Macintosh II GLUE chip.

#the-lab-hardware
Xiang spent much of the week chasing a horizontal video ripple on a recapped Apple Lisa. Suspicion landed on non-low-ESR replacement caps on the 12V line feeding the horizontal drive; various bypass-cap and 7805-regulator fixes (per the Lisa FAQ and Adrian's earlier fix) were tried without fully resolving it.zigzagjoe and Garrett dug into why Sonnet Presto/Tokamac LC 040 accelerator cards work in some Color Classics but not others — Garrett's testing across four logic boards froze on extension load, and Bolle suggested the issue is Presto driver version (1.3.1 or 2.x rather than 3.1) plus removing VRAM SIMMs. A long thread on soaring DDR4/DDR5 RAM prices spun into a broader Linux-vs-Windows daily-driver discussion (Fedora KDE, CachyOS, Mint, GoG launcher woes on Linux).

#vintage-apple
The big story of the week: Sharpie and twvd getting A/UX 1.1 installed, verified, and archived. Sharpie owned the original media but suspected his hardware was faulty; twvd verified the disk images in the Snow emulator, worked out the full partition/sash/floppy-root install sequence, and confirmed everything was good. Sharpie then got it running on his real Mac II (discovering it defaults to single-user mode — fixed by editing inittab) andposted the complete A/UX 1.1 floppy install set to Macintosh Garden, bringing this rare early release back into circulation. thecloud got the preinstalled 1.1.1 ISO booting in Snow (using the Toby video card instead of the 8•24). A lengthy, informative side discussion covered A/UX's real-world niche in the late '80s/early '90s — lab/industrial NuBus integration, in-house corporate software, and Apple Workgroup Server / AppleSearch deployments.

Elsewhere: killvore researched G3 accelerators for a 6500 and the quirks of running an ATi PCI card on a 6200 PSU (no 3.3V rail); a username needed help recovering an iBook G3 after a bad setenv real-base Open Firmware edit; jakuoreality battled OS install failures on a PowerMac G4 with a 160GBIDE drive; killvore diagnosed a G4 Cube that needs a charged PRAM battery to boot; and killvore also got repair advice (bad solder joints / possible lightning strike) on a dead 12" RGB monitor's mains switch. gogogoluke and Azryael had a good exchange on Macintosh Portable data-bus troubleshooting that branched into DFIR career advice.

#self-promotion
twvd released Snow v1.5.0, adding A/UX support (1.1 through 3.x), an emulated printer, new CD features, and floppy writeback — and published a companion write-up on installing A/UX 1.1. Ron's Computer Videos posted three "Let's Chat" interviews (Steven Lake / The Examined Game, Daniel Turner / Less Miserables, and Marcus Mera on Mystery House 3D). Jason Merrill teased a new video asking "Was the Macintosh Classic II Crummy?" seatsafetyswitch blogged about adapting a Fujitsu PC-9801 CRT monitor, and timw4mail released a new version of his Rustid CPU-ID utility. BigBadBiologist, Trina's Technobabble, HardwareHacker, and 1Bit Fever Dreams all promoted streams.

#the-lab-networking
daniel shared that the next Wireshark release will dissect two antique Apple packet types — MacIP (IPv4 over DDP) and the AFP 2.x ProDOS Info block — thanks to work with NJRoadfan. mbbrutman released a rewritten-in-x86-ASM DaynaPORT SCSI/Link packet driver for DOS ("smaller, faster and stronger"). daniel alsoannounced the inaugural 0.9.5 release of the Netatalk Client (a fork of afpfs-ng), aiming to be a cross-platform, full-featured AFP client, and a more-capable JavaScript engine build of MacSurf for Classic Mac OS.

Discord Weekly Roundup — week ending 2 August 2026

#the-lab-software

SHORK 486 had a very productive week. Admiral Shark added a long list of software to the 486-and-Pentium Linux distro: dialog, Make, NASM, GNU Indent, CScope and Ctags, Lua, the Tilde editor, Vim, and dosfstools + e2fsprogs (bringing ext3/ext4 and FAT12/16 support — FAT12 being handy for floppies). Tworounds of BusyBox expansion enabled 33 and then 18 additional coreutils/commands.

A couple of interesting constraints came up along the way:
  • Adding Make pushed the default build past the original 80MiB target, which was based on the ~80MB drive in Admiral Shark's ThinkPad 700. That sparked anopen question about whether "default" should optimise for a well-rounded experience instead of period-accurate drive sizes, with the custom build configurator as the escape hatch for anyone on smaller media.
  • Vim turned out to be a RAM hog on 486-era memory when syntax highlighting kicks in — the kernel was killing the process on machines with ≤24MiB and no swap. The fix was a wrapper in /etc/profile that creates a swap file sized to system RAM (clamped 16–128MiB, at most half the root partition)when Vim launches, and deletes it afterwards.
  • Rust is off the table for an on-device toolchain for now — timw4mail noted the Rust compiler requires SSE2, likely an LLVM constraint, though cross-compiling for 486-level hardware does work. Go had a similar problem: GOARCH=386 produced a binary that still wanted MMX, prompting the observation that "386" has become shorthand for "32-bit x86" across a lot of modern projects.
Following a post on r/writerDeck, a new "writer" edition was added, and the minimal/maximal build names were simplified to Mini and Max, with the build type now reported in SHORKFETCH output to make bug reports easier to reproduce.

There was also an extended thread on using LLMs for ROM disassembly. Kai Robinson fed the Inside Macintosh volumes to Claude and worked through several iterations on a Macintosh SE ROM disassembly, building a consolidated 639-entry trap table and posting the annotated output. techknight shared prior experience reversing XC2018 FPGA bitstreams back into logic the same way, with the caveat that the output needs checking — it will produce convincing text that mixes up registers. bakkus picked up the thread and started building on jonathanschilling's existing mac_rom project, aiming for a reproducible/rebuildable annotated listing, while being upfront that it's an experiment. techknight's interest is in extracting Color QuickDraw from the SE/30 ROM for use on accelerated 68000 machines, which was clarified after a brief mix-up over which model was meant.

timw4mail also published rustid 1.6.0 with Mac model detection.

#the-lab-hardware

The headline project is DosFox's "IIxi" — an all-through-hole, no-SMD test bed that's essentially an SE/30 using only the GLUE and ASC from a donor board, with the goal of eventually replacing both with functional equivalents (DosFox wants to build them out of PALs rather than an FPGA). Boards were ordered, arrived, and parts are on order. There's no FPU socket on this revision, so A/UX is out for now; it'll run a Rominator II ROM (IIsi or IIfx). zigzagjoe suggested shoehorning in at least a partial PDS slot for debug purposes so a BlinkenPDS card could be attached. twvd floated emulating it in Snow.

DosFox also laid out an Apple II mouse interface card from scratch — and then discovered while browsing photos that Apple's original used the exact same MC68705P3S microcontroller DosFox already has on hand. An Apple II SilenType sync card followed.

A long thread on the LC III "Ariel" chip: techknight described a failure mode where the chip stops producing a pixel clock (wobbly video for a couple of seconds, then eventually nothing), and noted you get death chimes with it removed — which led max1zzz to wonder whether the Sonora has its own oscillator. mmu_man dug into a Sierra SC11412 datasheet and the ø1/ø2/ø3 signals going to Sonora and Egret, wondering whether they're a bus as well as clocks. LC III schematics don't appear to be in the big Apple Data Archive (only LC II).

max1zzz reported that GALs/PALs are getting scarce — PALCE26V12s were locally available last year and are now near-impossible, and GAL26CV12Bs have gone from ~£1 to ~£5. CPLDs were agreed to be the way forward. (A programmer compatibility gotcha also surfaced: it supported GAL26CV12 and PALCE26V12 but not GAL26V12.)

The channel's cautionary tale of the week: zigzagjoe found an LLM-generated Sony CR-45 PSU "technical reference" being sold on Amazon/Kindle, apparently built by feeding Bomarc schematics, photos and measurements into a model with no disclosure of AI use. The consensus was that this is genuinely dangerous given the lethal voltages involved, and that "pretty close" isn't good enough for a power supply. zigzagjoe left an Amazon review; the author later pulled both the Reddit post and the book.

Also: elemenoh flagged Metcal's new MicroFine handpieces (12 grams, tips down to 0.1mm), and there was a good-natured tangent about using overpowered microcontrollers to replace a handful of logic gates — with seatsafetyswitch noting a sub-$1 PY32 came out cheaper than a 555 and some gates.

#vintage-apple

Busiest channel by far. Highlights:

Linux 7.2 booting on a Mac Plus. BicLighterEnthusiast returned to the server and got past a blocker that had stopped them last October — userspace now works, having previously crashed loading init. Next steps are a busybox build and a tty driver so there's a shell, then eventually a framebuffer tty so a separate terminal on the modem port isn't needed. An initial report of a STOP instruction bug in Snow was retracted — it had already been fixed, just an out-of-date build. bakkus got it partly running too, up until a kernel panic. Related: a SWIM floppy driver has landed in mainline Linux, and zigzagjoe's 68060-on-Mac patches were committed to NetBSD along with an ADB fix for the Q650/800 at higher clock speeds.

G4 Cube week. thecloud traced a non-booting Cube through the known failure modes — the 25-year-old battery still measured 3.66V, the touch sensor looked frazzled, but the culprit turned out to be the PSU putting out around 1V instead of 28V. The touch sensor "scotch tape with a small hole" fix was discussed for over-sensitive sensors (the isolating gasket dries out), and killvore shared the modern TDK Lambda DTM-series PSU they used as a drop-in replacement. Separately, Xodium fought a Cube that lost video entirely on ADC monitors when switching to 640×480 — isolated to the Nvidia extensions, with VGA completely stable — and repaired a failed optical drive that was hanging the whole IDE bus, reviving the rubber rollers with a dab of superglue.

Extended Mac OS 9 install troubleshooting. Ryker46859 worked through a long chain of issues on a beige Power Mac G3 with thecloud, bakkus and ptricky helping: a corrupt "Open Transport ASLM Modules" extension blocking the installer, a CD that wouldn't boot, and finally a working reinstall after initialising the drive from Drive Setup on a bootable CD. The MacSurf issue at the end turned out to be an application memory allocation setting. A side discussion on CD burn speeds produced mixed evidence — several people have had discs that only read correctly when burned slowly, while thecloud pointed out that bootability is a function of how the image was mastered, not burn speed.

twvd reverse-engineered the extended POST on the Quadra 700 and posted the full table of test codes ($80–$9B) mapped to the ROM's string literals, covering everything from the mapper RAM tests through SCSI, sound, PRAM, FPU, parity, the ADB microcontroller and the SONIC Ethernet tests. nulleric suggested putting it on TD so it gets indexed and found.

A long Mac mini 2011 dGPU investigation. MParaGames bought a macmini5,2 with a failing Radeon and wanted to know whether the Intel iGPU could be used instead. ptricky and Loafin worked through it: both display ports are wired to the Radeon, so blacklisting the driver just gets you an unaccelerated framebuffer on the same port rather than switching to the iGPU. The mux hardware that makes GfxMode=4 work on MacBooks relies on the internal panel being on the Intel side, which a mini doesn't have. Both GPUs showing in fastfetch just means both are on the PCI bus. The machine arrived at the end of the week and only shows an image under Linux.

Other bits: This Does Not Compute has a Sony MPF-52a manual-inject drive that always thinks an 800k disk is inserted and locked despite all three microswitches testing fine — BigBadBiologist posted comparison photos of the underside of a known-good drive to check for a missing pull-up. Sharpie got a newly acquired Apple /// running after blown RIFAs (with three more on the bench), then had a floppy scare that turned out to be a magnet-damaged disk — which led to the story of Apple's official "lift the front of the machine 3–5 inches and drop it" chip-reseating advice. Xiang is hunting for a period-appropriate SCSI-to-Ethernet adapter for a Lisa. killvore recovered a Norwegian keyboard layout by pulling the KCHR resource out of a System 6.0.7 image with ResEdit, and is planning an ATX PSU conversion for a Power Mac 6200 to get 3.3V for Alchemy-style boards. Oelmuvun found an AEK II underwhelming compared to Model F/M boards, which turned into a discussion of the various Alps switch variants and the general disdain for the AppleDesign keyboard. Clarus the Dogcow turned up on the front page of apple.com. And techknight noted the RTC rollover ahead — 2040 for 68k/classic, 2038 for PowerPC/OS X.

#the-lab-networking

daniel shared the ambition behind current Netatalk work: making AFP the best and fastest way to transfer and browse remote files generally, not just for old Macs — with classic Macs remaining a first-class citizen. DosFox is hunting for the original Kinetics Fastpath manager (not Fastpath II, which is on MacGUI) for a KFPS-1, and may well own the only one documented online — it has a 220V PSU, so it was clearly destined for the European market.

#vintage-programming

1Bit Fever Dreams described a Python memory-mapping tool built for the Wildbits/K2 project: four banks of 512kB SRAM viewed through the 6502's 64kB window,with an FPGA graphics side that can fetch from anywhere and 6502 code that very much cares. The tool spawns objects with defined sizes and start addresses, slides them around 2kB cells, gives an exploded view for cells holding multiple small objects, compacts them, and exports embedding instructions for a C source file.

#self-promotion

A busy week of streams and videos — see the links section below. Notable: Ron's Computer Videos published the first two batches of edited KansasFest 2026 sessions plus the virtual event schedule; Mac84 released a Macintosh SCSI basics guide; seatsafetyswitch started a blog series on the BBC Bridge Companion; This Does Not Compute did a live Macintosh Classic repair; timw4mail shipped rustid 1.7.0 with RISC-V support on Linux; and BigBadBiologist documented thatmoving resistors under a Kingston TurboChip 486 upgrade (R10 → R8) measurably improves L1 cache performance.
