Apple

by

So, I’ve finally decided to give it a shot. For a while I’ve had some interest in the various sensors Apple Watches have, and due to recent affairs, I pretty much find myself with greater need to be aware of what time it happens to be and whether or not there is a meeting on the agenda. Frankly, I’m tired of walking to the head or the snack bar and checking my phone for the time.

Combining these factors, along with the Xbox Series X continuing to be more Unicorn than not as far as budgeted upgrade paths go, I did something I rarely do: I bought myself an expensive birthday present! With my birthday coming up soon, I decided to pull the trigger and just do it. Something that’s not a unicorn always taps that earmarked piece of my savings anyway. Actually, thinking about it, if you discount that time I ended up needing a car near Christmas time, buying a Apple Watch Series 7 is probably the second or the most expensive ‘gift’ I’ve ever picked for myself šŸ˜ƒšŸ˜„šŸ˜‚. In retrospect, it’s also the first time I’ve ever been to an Apple Store, and probably the first time I’ve gone to a certain nearby mall in a about a decade.

My choice between the SE and S7 is mainly about the sensors; for all other factors I’d rather save on price. Of course, in September there will probably be nice sales if Series 8 lands at the usual time frame but I’m not a Virgo or a Libra. In terms of style being the bland sort, a nice black case and a dark green leather band in 45 mm. Something that fits both my taste and will blend in whether at work or out and about. Might investigate some of the NATO nylon straps and stainless-steel bands on Amazon for variety, but so far, so happy. The leather link uses a magnet clasp that’s as easy as Velcro, and more comfortable than the regular sports and leather bands with the usual through hole buckle that I’ve worn over the years.

This makes the third watch I’ve owned since about 1999, and the second that I’ve bought for myself. Remarkably, it’s also the most expensive. Back around ’99 is when I bought the watch that I used most in my life, for a whole remarkable ten bucks at Walmart. The only other watch I’ve used since then was a really, really slick hand me down. Until about 2010, I had intermixed between watch and watch less and set it aside sometime after adapting to phones in 2010. I can say that my desire for phones likely peaked somewhere in the middle and has long since waned in favor of tablets.

On the flipside, maybe the three rings will convince me to move my lazy fat ass more often ^_^.

For work related reasons, Iā€™ve found myself using a Mac for the past two weeks rather than my aging Latitude. Along with whatever the sale related winds happen to be when Stark finally retired, I suppose this will influence whether my next laptop ends up an XPS or a MacBook, lol.

Having adapted an iPad and fiddled around with old-ass PowerBooks, Iā€™m already well aware that Apple has its own standards when it comes to keyboard shortcuts, and that itā€™s probably as old as anyone elseā€™s :P.

One of the most annoying points of transition for me isnā€™t the control, option, and command thing ā€” rather itā€™s the differences in use. For the most part these modifiers are what youā€™d expect compared to control, alt, and super (windows). The part that will corrupt my muscle memory is some everyday control+shortcuts are control+shortcuts and some are command+shortcuts. Unlike a simple difference in modifier layout: this calls for learning which ones are and arenā€™t different modifiers; not just different key positions.

While the pattern is pretty straight forward for application specific shortcuts, e.g., cntrl+t to open a tab will almost always be cmd+t instead and changing tabs remains the control+tab of a PC; itā€™s the cursor movements for hopping by words and lines with the arrow keys that are harder to muscle memory. Those feel to have much less rime to reason to me. To balance that out, macOS comes with a version of vim pre-installed!

My relationship to Mac OSX was mostly focused on the unix layer. BSD with bits of GNU, and a little fruit on the side. Appleā€™s GUI itself never interested me much when I was getting deeper into computers.

As a consequence: I find the macOS window manager very ā€œDifferentā€, but surprisingly interesting. An early source of confusion for me was control+up versus control+down. One of these effectively shows the windows on the desktop and one of these effectively shows the windows for the current application. Thatā€™s the key.

macOSā€™s window manager is decidedly modern but it has rather classic notions!

Another source of such confusion is differences between cmd+tab and cmd+`, a distinction between applications and windows quickly becomes a ā€œHuhā€ when you start having handfuls of terminal windows intermixed with handfuls and handfuls of other application windows. If I hadnā€™t played with the classic MacOS, Iā€™m not sure I would have figured that distinction out as quick since no modern platform really does the difference between application window group and windows of the current application that way.

Actually, itā€™s surprising how much macOS has retained from the ā€˜90s and ā€˜80s era system software. Both in spirit and in direct function. While at the same time embracing UNIX, which typically takes a more ā€œPCā€ approach to things once you leap from minicomputers to microcomputers.

Done it again

So, it seems like I’ve done a naughty thing: I bought another vintage PowerBook. This time it’s a Duo 2300c.

A downside of 30-year-old Mac is the trackball is sometimes finicky and has proven resilient to my efforts. I’ve actually thought about acquiring a Wombat ADB-USB bridge so that I can use a modern mouse^ with my Duo 230. Later models tended to retain some serious hardware compatibility and reuse but eventually replaced the trackball with a standard trackpad. 

I’ve thought about acquiring a junked late model Duo for parts or trying to find piece meal parts of the old upgrade kits to refit my Duo 230 with a trackpad. Given the age of parts, probably better off with the Wombat approach. Encountering a 2300c in good shape that doesn’t cost more than a decent modern laptop of course was too tempting a target.

In my tastes for PowerBooks, things tend to lean more in the direction of subnotebook and ultra-portables. Even today, the Duo series greatly reflects my tastes in computing. 20-year-old-Mac’s PowerPC processor has been kind of nifty since it can emulate Motorola 68k and run native PPC code. But the ‘Street series is too damned hefty for my tastes even if its G3 blazes compared to an old ’30.

Interchangeability of parts between the Duo 200 series seems to be pretty high, but I’m not sure how true that is with the 2300c for internals. But unlike other PowerPC models I’d care for, because it’s the last Duo: it’s compatible with my peripherals. By contrast, other options lead in the direction of proprietary model-specific gear. The 2300c has the same dock port as the earlier Duo 200 series.

Depending on what shape its internals are in, I might end up with two functioning machines or kit bashing them together. I’ve been more interested in the 68k / system 7 era, but I can’t say that I really mind prospects of a 603e at nearly triple the clockrate of my 68030.

^ While I’m sure Apple must have made a decent ADB mouse at some point, I can’t say that I enjoy the rolling ball mice of old as much as I do an actual track ball or an optical based mouse.

Why iMac G4 is still the greatest Mac ever made 20 years later

While I canā€™t say that I ever thought much of the iMacs until I saw the modern style flats on peopleā€™s desks, I have to admit that the G4 certainly had a unique design. The original CRT design, I think would be deserving whether you wanted to give it an award for excellence or failure in style. But the lamp style G4s, at least were unique.
But Iā€™m pretty sure most people donā€™t want to experience 20 year old processors and the modern Internet :P.

Steve Jobs once chucked an iPhone prototype to impress a room full of journalists.

I kind of love this concept. Not because itā€™s the kind of gambit he might pull, but because it illustrates the point so perfectly. Unscathed or smashed beyond all recognition anyoneā€™s question about the deviceā€™s durability would have been reasonably answered beyond all doubt.
Plus thereā€™s another point: not to be afraid of trying. Iā€™m sure some engineer somewhere had quite the puckered ass at the time. But you canā€™t be held back by fear if you want to accomplish something meaningful.

For the most part Iā€™ve met iOS updates with the mindset, ā€œIā€™ll just be happy if itā€™s stableā€. Because when iPadOS 13 landed the features were much needed but the stability was crapola on my then young iPad Pro. Recent releases have thankfully been less hazardous and iPadOS 14 would become pretty stable for me.

Upgrading to iPadOS 15 thus far has passed the stability requirement. Plus for the first time it feels like new features have landed in a polished form. Running multiple applications using split screen, slide over, and the would probably confuse non nerdy users multiple instances thing, now work really damn well. iPadOS 15ā€™s the best implementation of such things Iā€™ve had since Samsung started to screw over theirs in favor of Googly multitasking and focusing on DeX.

So while I honestly could have cared less about the multitasking features earlier on, beyond slide over being a common offender in my iPadOS 13 instability, iPadOS 15 actually makes me view the fancy split screening stuff as a feature I can use.

Misc thoughts on System 7.5.0

Poking around the classic MacOS has been an interesting experiment.

One of the things I find remarkable, brilliant, and rather lovely is getting the old Macs to boot! Seems like just about anything with a usable system folder and a means for achieving block I/O from it will boot. Compared to mucking with MBR based chain loading schemes and infernally buggy BIOS this has been a good plus. Offsetting that is how Apple’s partitioning tool refuses to initialize SCSI disks without some kind of ROM identifying it as one of theirs, which seems to have been dropped by the later IDE days.

For the most part I have chosen to ignore the desktop on PCs in preference to a home directory. I’ve known people who cover the Windows desktop in icons all over. Mine has largely been spartan since I focused on UNIX systems, and since XP tried to make multiple users suck less on shared home PCs.

Classic MacOS on the other hand makes it curiously inescapable. It actually feels more like a “Shelf” to me than a desktop. Because its behavior is not like desktops that I am used to. On most “Desktop” operating systems that I’ve used: the actual desktop was simply a special folder. If you stuff a file on it the only difference from any other is not needing a file manager or a bunch of tabs or clicks to reach it later because you’ll just be moving windows out of the way to see it or using a shortcut to navigate there.

I’ve found that moving files from floppy disk to desktop doesn’t move the file off the diskette, so much as it seems to flag it as part of the desktop. Moving it somewhere else then generates the kind of I/O event other platforms do. Further when booting from other media: the desktop is subsumed into the current session. I.e. boot off a Disk Utils floppy and you’ll still see the desktop, but the icons for your HDD and floppy will have switched positions. That’s actually kind of cool in my humble opinion.

On the flipside the trash seems to work similarly. Trashing files off a floppy does not return the space, but unlike some platforms does send it to the trash rather than forcing a unix style deletion.

When working with the desktop and your hard drive: placing data on the desktop seems to be treated like the root of the drive. Opening a file info dialog will show a path like “MacHD: My Folder or File”, and you won’t see it in the actual drive: just the desktop. One thing that made this apparent to me is the option to default to a “Documents” folder for the file open/save dialogs. System 7.5 created a Documents folder on my desktop but it doesn’t appear in MacHD despite the path shown in Get Info. I opted to leave an alias on the desktop and move the original into the HDD view, reflecting how I found the file system from my Wallstreet’s MacOS 9.2.2 install.

At a more general level is the feeling that Apple’s designers really did not believe in the keyboard. There are shortcuts for many common tasks, but when it comes to manipulating text the system UI has been use the mouse or piss off. Even simple behaviors we now take for granted like shift+arrow to select text do not exist in System 7.5. Fortunately, I actually like the trackball :P.

Thus far, I have found System 7 rather interesting.

On the PowerBook Duo 230 AKA 30 year old Mac, I’ve got 7.5 running off a BlueSCSI mounted internally. Tech by Androda has a PowerBook configuration that comes with a lovely 3D printed bracket, which was easily mounted using the rails bolted to the original Quantum drive. The only real problem that I had was initializing the drive, in the end I opted to download a prepared blank image. As far as I can tell the difference versus dd’ing my own is Apple Partition Map, Eventually I need to find a nice disk utilities package that fits on a floppy, as the Disk Utils disk offers me little value beyond it boots and has a system folder.

Installing was fairly straight forward since I was able to build floppies using the PowerBook G3 AKA 20 year old Mac. No idea of how, but disk one appears to be bootable but ha sno system folder visible like the Disk Utils disk. The installer however kind of sucks. Attempting an easy install takes about 20 – 40 minutes of swapping 7 floppies, and then dies and deletes the entire staging area off the disk. So I went about doing a custom install piece by piece and determined that its the Apple Guide on diskette 7 that causes this. Also for some reason it follows a pattern of eject disk 1, ask for disk n, eject and ask for disk 1, eject and ask for disk n; whenever I first start installing some item from custom install. Making this whole process a pain in the ass. Once in a while it decided to want to floppies at once. So, while I kind of love how easy it is to get classic Mac OS to boot: I think the 7.5 installer sucked. It is however quite simple and easy to use, if you can get it to work :P. At 7 floppies plus a Disk Utils, it’s not too large a set either.

Beyond that however, it works superbly and for a machine old enough to have school aged children of its own, I find the Duo 230 quite snappy. The real pain was trying to get Stuffit Expander loaded, since getting the images to mount on my G3 was mostly an exercise in futility. Once I finally got the disk made, I both set the write protect tab and wrote a message about not losing the disk because it’s a pain to build. When I was putzing with Basillisk II on my OpenBSD machine it was fairly painless because I could just mount the image directly. In System 9.2.2, I ended up using grabbing the Virtual DVD-ROM/CD Utility off Macintosh Garden. Disk Copy and ShrinkWrap told me to eff myself. Trying to mount in Toast just froze the G3 such that not even the mouse could move. Never liked Roxio on Windows, and don’t think I care for it on Mac either. Needless to say I wasn’t happy getting StuffIt Expander onto my Duo!

One thing that remains to be determined is whether or not I care to migrate to System 7.5.5, or a larger internal image.

Testing 7.5.3 -> 7.5.5 in the emulator was a fairly painless experience. Give or take that it takes forever to unstuff large files compared to my Duo. The StuffIt archive is 70~80 meg. More general stuff in the emulator seems to suggest 7.5.3 improved performance on 68k processors, not just on the younger PowerPC processors. But overall seems less important without a PPC based Mac. Given the size is something like net install + 19 floopies + 3 update floppies, I’ll probably defer that until I have a working RaSCSI where I can just place the files rather than imaging a ton of diskettes.

Regarding the disk images, I’m less decided. I chose to setup BlueSCSI with a 250 MB image. Partly because I just wanted to see it work, and partly because I intend to have RaSCSI be an external drive to shuffle between systems. Considering the Duo came with a dead 160 MB drive and they apparently were sold in 80 MB and 120 MB configurations, I’d like to think 250 MB is a nice balance between the hardware’s era and large enough not to care. Between system folder, basic software, and copies of the floppy loaded setup files, I’m only using about 30 MB. I plan for RaSCSI to present a large 4 GB volume, possibly several; but I could just as easily use that internally.

One oddity: the maximum date. Despite HFS having a limit of 2040 for its max date, I couldn’t go past 2019 without the date wrapping around to 2019 in the control panel. Apparently this was a bug in the date/time control panel, and someone wrote a nifty control panel app that lets you set the date correctly.

Sometimes to fix a 30 year old computer, you’re better off buying a 20 year old computer to help

by

A few months ago, I picked up a 12″ iBook G4/800 MHz to use as an OpenBSD/macppc experiment. After the Duo’s power supply went poof, I was rather hesitant to spend $30+ on a replacement that I would likely have to split open and re-cap to avoid a repeat of said smelly poof. Since the iBook G4s still used a 24 volt charger, and mine already had a replacement tip scarily attached. I decided to buy another G4 charger as a replacement, and attempt to graft the Duo’s tip onto my G4’s charger.

Sadly this proved unsuccessful, be it my limited soldering skills or the problem of figuring it how the old replacement tip’s three wires were adapted to the G4’s one wire and ground, it didn’t work. So I decided to do a bit of research. Excluding a brief difference in the 500 series it seems that Apple largely kept 24 volt chargers from at least the early ’90s PowerBooks up until the early Clamshell G3 models with the hockey puck, and swapped tips towards ’99 or ’01. It’s kind of hard to find one of the hockey puck chargers, and much like the iBook G3, I really can’t decide if the design was genius or silly.

In my efforts to dig up a replacement charger, I ended up buying a 20 year old mac to help me fix a 30 year old mac. Got a good price on a 14″ PowerBook G3 series, which from the 233 MHz/512K/etc on the bottom I suspect may be a PDQ. Since this machine happens to have both 10BASE-T Ethernet and a floppy drive, it’s made it really handy to try and deal with abusing software onto floppy diskette with disk copy. The machine even came with a CD-ROM module, user manual, emergency guide, and some spare floppies.

Opening up the PowerBook G3, I really, really, really hope that whoever designed the internals won an industry award or at least got a huge bonus. Eject the expansion bays, push the switches and pop goes the keyboard. Unscrew and yonk the heatsink and vola memory, hard drive, right there. Makes working on my old ThinkPad (and pretty much very laptop I’ve ever touched) look hard by comparison.

Not sure if anyone fathomed how useful the mix of old and new ports on the Wallstreet/PDQ would be for something like this. Having 10 Mbit/s Ethernet and a version of Internet Explorer 5 that’s better than my first Pentium machines kind of made my chuckle, but is quite handy. While at the same time it has the same kind of ADB keyboard/mouse, HDI-30 external SCSI, and mdin serial ports my Duo has. Not sure what to make of the S-Video, other than to remember way back then we couldn’t afford TVs now computers with that šŸ˜œ. On the positive side looks like it also has a real VGA instead of the whatever-the-heck-Apple-dsubs were that my Duo has.

Duo 230 off G3 charger

More importantly the M4402/1998 charger works as a perfect replacement for my blown M7783/1992 charger ^_^.
