Just tested myself for the sake of it, it happily triggers overcurrent protection at 1.3A if I let it charge on a bench supply. So definitely needs some circuit to calm it down.

Updated the model to make it easier to assemble with the meter.

So, the only thing I hate more than people forcing me to published unfinished work because they are redoing what I spend nights already doing, is people wasting time doing what I already did… https://github.com/mmuman/cad-mac-pb500-pwrconn Oh, and a voltmeter variant, because people love...

So, instead of just doing the math and applying the datasheet for the chip I found, I started writing a KiCad plugin to do that for me… Someday I should just do stuff instead of spawning other projects :LOL:

So, as discussed on MLA, and I tested it, it seems the battery is hooked directly on Vbatt without any current limiter in the laptop, so if we want to charge as well I'll have to design some PCB to add inside. I think it's possible. 🤞 So, someone confirmed using 15V Vmain without trouble for a...

I started designing the connector years ago but never really finished, I planned on using step-down boards and designing a case, much like @PotatoFi ended up doing for the 1xx series. I was a bit reluctant to sending only 15 volts, and I'd have liked to be able to check on schematics, but I...

I dug an old unfinished thing… and tweaked it a little… spoilers!

What about https://oldavista.com/ ? :D

On a request by @XodiumLabs I made this little base to light up your G4 Cube. You can find photos on Xodium's Cube thread. The files are on Thingiverse, and on MS GitHub. You can adjust the height and thickness on the OpenSCAD model.

Like last year there will be a retro devroom, the CfP is here.

I also noticed that after taking care of my LC-III, on the next one I noticed that and went back to fix it. It seems people "discovered" that just now again. 🤷‍♂️

In case you missed it, the FOSDEM RetroComputing devroom CfP is out. Deadline is December 1st. It will take place in Brussels on February 2nd.

Indeed, that's what egretrom does (it's linked to from the thread's first post and the image contains source code): thePB.pbCmd = 0x2; /* read 6805 memory */

Actually it seems I posted it on this same thread in 2023 😅 Thanks :)

When I say I'm on it… I'm on it. I spent nights digging the schematics and comparing pinouts, and producing that spreadsheet, but you didn't ask :p I also patched radare2 to fix support for 6805 disassembly so I could reverse the other dumps, but haven't finished yet. Fixing tools takes so...

It's not the only one that might work. I've been on that for 3 years :p Which is why I didn't go the simple programmer route because they all have their own variant and I didn't want to make 3 different boards. I have a prototype programmer already but the software is not yet working.

Well, it's not that old… incidentally someone prodded me into looking at it again this week-end, so…

I'm starting to have some stuff to sell… Joe told me Tindie had some issues (like, not allowing different items per order!?), anyone experienced that? I'm already behind on sysadmin for other servers, I'd rather not have to maintain my own shop…

Last changes on these, I think we can ship! Wait, I don't have a shop yet 😅 Protos from left to right, original on the right.

Nice result!
