Getting with the 21st century

Thanks to a bit of Christmas goodness and Microcenter having them 50% off, I finally got myself a NVMe style portable drive. A while ago, I had tried to find one that would have a slot for my lanyard and only could find expensive SanDisks that would meet that criterion. Thus, fire sale equal fire win.

Which gives me a superb replacement for my ruggedized USB-A hard drive. My old drive has served well, but it’s a spinning platter that I bought back in 2014. Making it about 8 years old. Getting USB-C and fancy speed is just a win. Since it includes a suitable C-to-C and a C-to-A adapter even my old development beast, Stark, can utilize it. I had figured the old drive would remain for his backups but probably not.
Rimuru’s 10 Gbit/s ports give me in the neighborhood of 860 MByte/s reads and writes. Rimuru and Stark’s 5 Gbit/s ports basically max out around 460 MByte/s.
Sorting through my usual backpack, I’ve decided while I’m retiring the ruggedized hard drive from my standard work and travel kit, my null modem cable is going with. As much use as I’ve gotten out of a serial cable in the past decade, I’ve also found it somewhat sad that I still carry a null modem cable…. lol.

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

While I can’t say that I ever thought much of the iMacs until I saw the modern style flats on people’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 I’m pretty sure most people don’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 it’s the kind of gambit he might pull, but because it illustrates the point so perfectly. Unscathed or smashed beyond all recognition anyone’s question about the device’s durability would have been reasonably answered beyond all doubt.
Plus there’s another point: not to be afraid of trying. I’m sure some engineer somewhere had quite the puckered ass at the time. But you can’t be held back by fear if you want to accomplish something meaningful.

For the most part I’ve met iOS updates with the mindset, “I’ll just be happy if it’s stable”. 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 15’s the best implementation of such things I’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.

Somehow the thing that really bothers me about transferring files this way, is the speed.

Not because it’s ridiculously slow by modern standards, but because it’s nearly twice as fast as my last dial up connection in the ’90s 🤣

When you end up transferring files over a serial port between computers made in 1992 and 2021, I’m not sure if you’re crazy or have a strange concept of relaxing.

That said my PowerBook Duo’s Printer-modem port seems to support a whopping 57,600 baud. Which works out to about 4.5 ~ 5.2 KB/s using ZMODEM between TeraTerm and SITcomm. Perfect for listening to music or making a sandwich as files transfer.

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.

Things that make me mildly sad:

  • That when I got my first CD-Burner, CD-Rs were so expensive we could only do backups about once or twice a year.
  • I bought a spindle of like a 100 DVD-Rs less than a decade ago, and I may not be able to use them up before I did without stooping to using them for Frisbees and coasters.
  • How I rarely need to use CD-ROM or DVD-ROM but inevitably
    • Need CD at home because the drive won’t do a DVD, of course I only have DVD-Rs.
    • Need a DVD at work because the data won’t fit a CD, of course I only have CD-Rs.
  • That at this point the only reason to care how many discs I use (or waste) is the wear and tear on my BD burner.
To which I’ll add that time I saved $5 to $10 and got a CD-ROM only external drive instead of a DVD-ROM one was probably one of the dumbest ways I ever tried to save a few bucks 😜. The irksomeness of hauling it out of the closet aside, the USB enclosure my old Blu-ray drive has been in kind of…rocks.

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.
