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...

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...

Hi all, I need a new battery for my PowerBook… Short background (feel free to skip): I built two batteries for my PowerBook 170 back in 2017 (briefly documented in this thread here and here) that I've been using regularly since then. However, all of a sudden at the end of 2020, they both...

I've been thinking about writing this post for a loooong time, but I've felt that the idea was a bit too far-fetched, and that it would put the biggest effort on someone other than myself, so I've decided to focus on other projects this far. But since @Crutch opened the door for it to perhaps...

Just a simple C (Think C) question here. Can anyone explain why these two methods give different results? I have a decent understanding of how floating point numbers work in binary (5.67999…) and the problem with rounding during assignments, but I'm surprised that these two methods give...

While searching for some files with Apple's Find File app using the date options (something I often do), I noticed I wasn't getting the results I expected. After some testing, there appears to be a bug which manifests itself in the following, somewhat peculiar way: If the system clock is set...

Has anyone here successfully run the Reminder app from Dave Mark's and Cartwright Reed's "Macintosh C Programming Primer, Volume 1, Second edition"? When checking the syntax, Think C complains that "Pointer types do not match" in the two lines below.       GetDItem( dialog, iLaunchCheckBox...

Hi everyone A while back I had the idea to begin learning to program, and what better way to do so than with C and the Macintosh Toolbox  :)   It's mainly a hobby at this point, and I just see it as a nice bonus to learn some general programming concepts in the process. I've recently moved on...

As anyone who owns one of the original PowerBooks knows, the I/O port door with its latch/tab and power button behind it isn't the smartest of designs. Since I got my PowerBook 170 back in 2001 I've been alternating between using it without the door (not that pretty), with a door with the tab...

Does anyone here have any information about the layout of the PowerBook 170/140 motherboard? Since a couple of months back, I've had problems with my PowerBook 170, somehow related to the AC connector (I've been using the computer more or less daily since I got it back in 2001, averaging about...

Hi everyone!   I have an old and classic PowerBook 170 that I'm still using (along some more recent equipment, perhaps I should add :) ). Unfortunately the screen backlight is on its last legs. Since I recently upgraded the storage to a Compact Flash-card (through the amazing PowerMonster II)...
