    How do I get screenshots from System 7.5.5 into a usable format?

    Surprising that you are unable to open it in other applications on the mac. I've never had any problem with that over the years. Are you running at an unusually high resolution and bit depth in combination with very little RAM? Perhaps you could try enabling virtual memory (or, preferably...

    New to me PB180...it's dead Jim...

    I’ve never heard of this being a problem, but I’m throwing it in here just in case. I’ve noticed on my PowerBook 170 that if any of the keys on the keyboard are pressed when the power button is pressed, nothing happens. Release the key and the computer starts up. I suppose, if any of the keys...

    Adjusting levels in Photoshop changes both image brightness and desktop brightness

    Oooh, very cool! 😲🙌😃 Like it's said, a picture paints a thousand words. Thanks for sharing!

    Adjusting levels in Photoshop changes both image brightness and desktop brightness

    I think we need to give you a small award for sticking to describing it as a problem 🙌😄;) But in support of your view on it, it's a rather crude and far from ideal solution since you lose all onscreen references for the adjustment you make. Probably best to make the adjustments in fullscreen...

    Adjusting levels in Photoshop changes both image brightness and desktop brightness

    I don't know if you're convinced yet @capa150 :) but like @Phipli said, it's very much by design. It's incredibly helpful to see a live preview of the adjustments one makes, but in the early days of Photoshop, image calculations were fairly processor intensive. So simulating the adjustments by...

    Can the PowerView driver be modified to support other resolutions?

    I've had a Radius PowerView for many years. I've pretty much only used it once every two years or so, either when I've done maintenance or upgrades to my PowerBook 170 and needed to use the computer with the screen disconnected, or sometimes to play some old, nostalgic DOS games through...

    Sneak preview: TouchScroll cdev

    Wow, that's really cool! I don't own a tablet, and pretty much only use emulation on the occasional moments when I need to try something out in color that doesn't work in OS 9 on my Quicksilver G4 (the only other Mac with support for classic Mac OS that I own, apart from my old Classic II, and...

    PowerBook 170 display housing disassembly help

    Haha 😂 Great that you fixed it! Sounds like the same basic idea, but with a less finicky method :)

    PowerBook 170 display housing disassembly help

    Haven't tried this myself, but instead of using a screwdriver, perhaps you could get a pair of tweezers (preferrably with some type of hooks at the ends) and use them to pull the screw towards you, and utilize the friction between the insert and the hinge to keep it in place while, carefully...

    We've got a problem... ...and a solution! (PB1XX permanent brittle plastics / screen hinge fix)

    Interesting. Did you document it anywhere? The only solution I’ve come across this far is 3D printed replacements for the screw inserts. Regarding the longevity, both the front and back part of the housing showed cracks at around the same time, so I don’t think the old drilling fix affected it...

    We've got a problem... ...and a solution! (PB1XX permanent brittle plastics / screen hinge fix)

    The problem… A bit of background/history: Almost immediately after I purchased my PowerBook 170 back in 2001, two unfortunate accidents happened. After only using it once or twice, a crack in the insulation at the tip of the AC plug (a problem affecting the first version of PB1XX...

    Open system call failing on System 6 but working on System 7

    Oooh, that answers something I’ve been curious about for a long, long time! I frequently transfer stuff from OS X to my PowerBook, and as a result, hidden .DS_Store files are scattered all over the disk. Then whenever I run Norton Disk Doctor to check the system, it neatly puts together a list...

    Idea/dream/wish: Exposé for classic Mac OS

    I'm still using beta 4 daily, and it's working great. Would be nice to get the speediness of beta 5, sans the bugs, but take your time. Good luck with the new house!

    I need a new battery.

    Thank you for your thoughts. Since I wrote the post I have abandoned the idea of modifying the power bank's output, and instead plan on drawing power directly from the battery terminals (while still, hopefully, being able to rely on the BMS for safely charging the battery via USB). The main...

    I need a new battery.

    If voltage converters that provide a stable, linear conversion (where the output voltage equals the input voltage plus/minus a set amount) aren’t available, would it be possible electrically to somehow combine/offset the converted output voltage with the unconverted voltage? Anyone with...

    I need a new battery.

    My plan is to keep the power bank's circuity intact, to be able to conveniently charge the pack with standard USB chargers, and add a separate power converter for drawing power from the battery. I guess what I meant was unregulated power converters. Wikipedia's article on boost converters...
