    Recreating the Mac's CUDA / EGRET microcontroller chips - can it be done?

    Last I looked at it, there was one HC05 chip that was supposedly still compatible with the original HC05E1 that Apple used that possibly could use the binaries as is. Haven't had the time to investigate any further. Seems UTSource (hmm, right… "used" OTP?) & octoparts still has some, but I never...

    Repairing PowerBook 140 standoffs

    I have a 180c open on my table here and some posts are partially broken, but I wanted to try and glue them back first. Anyway, can't look at it until next week.

    Oh, I need to add the mirror as well, they are not symmetrical… EDIT: done.

    PowerBook 1xx kickstand / flippy foot

    Not sure how to name these, but I made the model. Still untested though, and I'm not sure of the screw pitch yet.

    PowerBook 1xx PowerDoor™ remake

    I have a 520c here with the port cover, I could probably model it someday. But not this week.

    Did you change it since the last you sent me? The one I use is on the github too.

    No that's the original product which was molded back then. :-D No exact match yet though.

    PowerBook 1xx hinge cover remake

    And again someone on the Discord pushed me in getting one more thing modeled… I left my calipers at the fablab so it might still need tweaking… Source here, you can get STL directly from cadhub for example.

    PowerBook 1xx PowerDoor™ remake

    The other day someone posted a nice picture on Discord of the "PowerDoor™" replacement ports door for the PowerBook 100 Series, which includes holes for both the power button and the modem port. I knew I saw an existing model for the regular door, so I quickly made a mod in OpenSCAD, which can...

    PowerBook 1xx Trackball Ring

    Instead of finishing my many other projects or doing the overdue paperwork, yesterday I modeled this part that was requested on the Discord. There's an "FDM optimized" version that puts the notches as indents to allow printing with top on the bed. @SuperSVGA managed to get a good looking...

    HDI-30 Part Number?

    Ok, now you'll make me think about it all night long instead of sleeping… I have a plan… 🤔 Btw, I already had measurements taken, the horizontal pitch is (11+7.8)/(2*(6-1)) = 1.88mm and the vertical pitch (4.5+7.3)/(2*(5-1)) = 1.475 … which I'd round to 1.5mm.

    HDI-30 Part Number?

    I'm afraid the FCI one doesn't have the correct pitch, looking at the drawings. I remember looking at those without much luck either. Which one did you need Ron, cause I'm planning on recreating a male one, but I wasn't thinking about the female part. I suppose I could look into it too.

    PowerBook grey filament? Which RAL?

    So, I checked with the older Powerbooks I have, and they are even closer to 7012 (Basalt Grey), I think we'll have to go with that.
