    A/UX Mac-side hybrid applications: some notes on building them.

    There don't seem to be much information out there on writing applications for A/UX that aren't just ports from other UNIXes. I've now written a couple of Mac applications that use A/UX facilities—and I've done it more than once, so by YouTube standards that means I'm an expert. Heaven help us...

    Long shot: A/UX and spurious ENOTSOCK

    While I've been away from home I've been playing with writing a hybrid A/UX application or two. I'm hitting a very strange thing, and I'm posting in case anyone has any ideas. I'm using ordinary UNIX sockets for TCP, using the normal send/recv affair. Every so often, after somewhere between a...

    Patching _ExitToShell for application cleanup: any experience?

    When talking about making sure you don't have any outstanding VBL tasks when a process exits, IM:Processes helpfully suggests: I'm not sure about "easiest", but this procedure sounds both very useful and fraught with danger. Has anyone done it before?

    A/UX note: /mac/lib/Patches—why are there two files?

    I spent the last couple of evenings tracking this down so I thought I'd leave a note here in case anyone else needs to know for whatever bizarre reason. This may, of course, be common knowledge and I was just looking with the wrong keywords. If so, it's been a learning experience. A certain...

    A/UX "MacTCP" driver—where is it?

    I'm trying to track down an A/UX oddity where I'm getting spurious MacTCP errors. I know that A/UX's MacTCP isn't really MacTCP, but is a compatibility layer. Presumably this compatibility layer is a driver somewhere, because, after all, its published API consists almost entirely of PBControl...

    A/UX and ZuluSCSI: a note for future searchers

    A/UX 3.0.1 installs from a ZuluSCSI fine and easily, no need to muck about with optical media. I just did this on a Q650 today. Copy a big empty HD image to the SD card as hd0.img and copy the A/UX CD as cd1.iso or some other ID if you prefer. Make sure the Apple Quirks switch is set. Then...

    How does the .MPP driver work?

    I'm confused by the structure of the .MPP driver. This is certainly the case for the one that came as far back as System 7.1, which is the earliest I've got on me. Normally, you'd have a driver header that points to the different routines the driver provides, followed by the routines. That'd...

    Fix report: SE, screen collapse to single line while adjusting height

    Another slightly odd one for people's information. Symptom: SE AB with badly-adjusted height image: while adjusting the potentiometer the screen collapsed to a single line in the middle of the screen and turning the pot had no effect. Cause: Turned out that the height potentiometer itself had...

    System 6.0.7 LocalTalk Network Access Disk

    I set this up for my own use and thought other people might find it useful. It's a floppy image with 6.0.7, AppleShare and the DisklmageMounter control panel on it, intended for use in installing operating systems over a LocalTalk network. That's about it, but it might save someone some time...

    Building a new LocalTalk (and LToUDP) to Ethernet gateway

    Following on from the 'What should a hobbyist-focussed AppleTalk router do' thread in the Networking subforum, some new prototype boards arrived in the post a few days ago. I haven't brought all the peripherals up yet, but here's a thread to whet people's appetites. This board contains all...

    What should a hobbyist-focussed AppleTalk router do?

    As a companion / follow-on piece to AirTalk, I've been considering trying to build a new AppleTalk router (either just software or a software/hardware combination) aimed at hobbyists. I'm starting this thread to try to get some opinions and/or interest going around what, in broad terms, this...

    Trip report: Internal scuznet install in an SE

    I have an SE that contains a Radius 020 accelerator. Further PDS expansion on top of the accelerator would have to happen through the MagicBus slot, and there was never an Ethernet card that plugged into that slot. I also had one of @saybur's scuznet boards (built by @aladds), so today @joshc...

    DDP socket and type numbers

    I'm assuming this was never published, but on the off-chance—does anyone know whether there's a list out there of all the Apple-defined DDP statically assigned socket numbers and/or DDP types? For context, I want to do syslog over DDP broadcast, which will require a static socket, and I don't...

    What's inside a Cayman Gatorbox CS?

    The Cayman Gatorbox series are AppleTalk routers with lots of bells and whistles, like being able to proxy NFS shares to AFP and being able to proxy PAP printers to lpr clients on Ethernet. I got mine out to play with AirTalk interop testing, and thought I'd take it to bits to check what state...

    Force32: persistent 32-bit addressing without a PRAM battery (updates thread)

    It's time to resurrect the Force32 thread! Force32 is a system extension that makes your Mac always run in 32-bit addressing mode, even without a PRAM battery. It works by, at startup, checking whether 32-bit addressing is turned on in the xPRAM; if it is turned off, it turns it on then...

    Introducing (and interest check) AirTalk: Wireless plug-and-play LocalTalk dongles

    I think this is the moment to unveil something I've been working on for the last few weeks. This is AirTalk (thanks to @Cory5412 for the name). It aims to allow wireless LocalTalk networking (over WiFi) that feels like LocalTalk: so, no necessary configuration (aside from selecting the WiFi...

    Why and How to build your own Chooser Extension

    There doesn't seem to be a good walkthrough or discursive tutorial on how to build Chooser Extensions out there, or indeed why one would want to. Furthermore, when I sat down and tried to learn it, it turns out that Inside Macintosh is wrong in some important ways and the other documentation I...

    A note on RDEV/PRER ("Chooser Extension") development

    In IM: Devices, the sparse documentation on how to write Chooser Extensions includes the following useful comment: "You should also include a 'BNDL' resource (and appropriate icon family resources) to give your device type a distinctive icon because this may be the only way that devices are...

    Mac Plus internal SCSI: noninvasive edition

    Today I successfully installed an internal SCSI disc in a Mac Plus "noninvasively"—that is to say, without any modification of anything original in the Plus, just clip-on things and replacement cables. I thought people might like to see what I did and how. It's been reliable so far today, but...

    Fix report: WibblyPlus Wibbles No More

    Following my normal habit of posting non-obvious fixes for other people to find: Symptom video: (thanks, @Paulie) Macintosh Plus. Definitely an analogue board problem; swapping AB made it go away. AB already recapped. Capacitors of decent quality and known to work in other ABs...
