I did not even notice :p  So I guess designing a cheap (< $10) HD30  to DB25 could be a good idea :)

I did not know about that, nice ! I wonder if designing one would be worth it ?  Pros :  - fast to design - cheaper (especially because the one you suggest does not cheap to EU) If I can't find one to buy on ebay I'll do this little project I think :)  

You mean Powerbook 190 right ? I just bought a powerbook 150 so I should be able to test and design an adapter for this connector :p  

Congrats on all the work done ! I'm really impressed ! Good luck for the future of this project :)  

Sorry I'm not sure to understand what you mean ?

Juste received the PCB from China, next step is soldering and testing ! :D  

I just received today my digikey order, and I should receive my jlcpcb in the evening. So in the nest 10 days I should be able to let you know what is the status of the project and if I need a new revision of the board before getting to to the final version. I'l let you know soon !

Did you have a look here : https://www.abebooks.com/servlet/SearchResults?cm_sp=SearchF-_-topnav-_-Results&ds=20&kn=Macintosh Family Hardware Reference&sts=t ?  :)  

The only other solution I see would be to design the board for internal use, and get power form the molex connector. But that would mean that people will have to mount the board inside tue Mac, and as you already chose a case I guess that’s a no go. Btw it’s really interesting what you found...

You’re completely right. But I assume these are the official specs and that most usb wall chargers that are able to deliver 1A and more will deliver it without negotiations. (Maybe I’m mistaking ?)

You could manage to get power from USB, so you could easily remove the jack :)   I also added a double DB25 port to be able to daisy chain the board, I used this one : https://www.digikey.fr/product-detail/fr/adam-tech/DPD-25-00-B3/2057-DPD-25-00-B3-ND/9833611 You can have a look at 68net...

Also why did you choose not to make the ground plane fill the whole board ?

Oh ok my bad, if you're using an external antenna that should be find :)  But why not use the onboard ceramic ? :)

Cool project ! I hope to design such a thing when I finished a wired (ethernet) version for the 68k machines. I don't own such a machine as your powerbook but I had a quick look at your design. Be careful with the traces going under the antenna, you should avoid that. Maybe try to move the ESP...

Glad to hear it's not black magic. But still it's really frustrating :/  

I agree this is super weird. I'm sure I am the one who did this to the case. I dismounted the mac, remove the back screw of the CRT, and then put back the exact same screw (and the same CRT)) and when I finished assembling the mac back I saw this little bump. It's super weird that the screw...

Oh I see you would want to hide the raspberry pi inside the SE/30 case ? I think I would just leave it outside the SE/30.

Nothing prevents you to plug 68net to a raspi via ethernet. You can then have an AppleShare server on the raspi, and the raspi could bridge ethernet to wifi/internet. This is quite easy. I'm not sure to understand what the problem would be ?

Thanks :) Making different PCBs for each Mac would not make a lot of sense. But I'm working on 3D files to fit the board internally (at least for the SE/30 as it's the only compact Mac I have (yet :p) ). I'm also working on a little adapter 50 pin -> DB25 to connect to the internal SCSI...

Can also something like that be fixed ? (I think I may have tighten too much my CRT and it made that little bump)
