    Micro-Alchimie (France)

    Last week-end we had 65 people gathering in a minuscule town in France with old computers… Some people took photos. I fixed some stuff there (like an N64 PSU brick, an Amiga RAM card…), and we had a lot of fun.

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

    Been working on making fixes on 6805 support in Radare2 to help with reverse engineering…

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

    Oh I have a Tanzania based clone, I'll have to dump that one I suppose.

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

    I've checked many schematics and compiled the pinouts, and this is just a myth, it's the exact same uC with the same pinout and just an Apple reference painted over. They just changed the function of some pin but that's it.

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

    So, I had some things ordered from uncle ali, some arrived already. If other activities permit I might find the time to build a programmer. I also need to design a same-footprint SOIC-28 socket because those don't exist.

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

    Well it's the occasion to fix r2 as well. Is the caboose one in the Mac_ROMs file? I only find 3 EGRET and 3 CUDA files in there. Plus if I can find what I want we won't even have to recode this anyway.

    You on Mastodon?

    Well, why not… Anyway you don't have to go to Mastodon, you can go to Pleroma, Misskey or some other platform that are also part of the great Fediverse.

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

    I looked at the disassembly on github mentioned on MLA, but it's really partial and only for one version. I then looked at Radare2 to automate this but the 680x backend seems really unfinished, it even stripped the last character of each disassembly line… So this can take a while as I'll have to...

    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.

    PowerBook 1xx kickstand / flippy foot

    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 Trackball Ring

    Updated the model to make clips stronger, they shouldn't break anymore.

    PowerBook 1xx hinge cover remake

    Oh I didn't notice the top was clipped since I fixed the height. Corrected.

    PowerBook 1xx PowerDoor™ remake

    not the bicolor one.

    PowerBook 1xx PowerDoor™ remake

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

    PowerBook 1xx PowerDoor™ remake

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

    PowerBook 1xx hinge cover remake

    Updated the model with proper measurements, wasn't too far off.

    PowerBook 1xx hinge cover remake

    Oh there's a small detail missing still.

    PowerBook 1xx PowerDoor™ remake

    Thanks, fixed the model.
