Finally had time to test the new boards, just to discover I made an error and the regulator releases the magic smoke. Who can spot the error? sigh Time to make a next batch of boards I guess.

Is Mini vMac on GitHub? I was able to build it on Mac and Linux (not windows), would it be possible to make a fork with binary releases (and maybe fixes)?

I hope to finally make it to test it in LT2USB this coming weekend, free time has been elusive lately.

I just bought a NUpowr 117 PPC upgrade for a powerbook 5xx (which I don't yet have) as the fist step to reproduce my fist "real" laptop (a 520c with said upgrade, that disappeared with the friend I lend it to). Somebody please suggest excuses not to feel guilty!

Ohhh fantastic job! The IIci was the first computer I've ever used, it was my father's and he used it up until 2002 or 2003. Very cool machine, I remember setting it up for dialup internet in 1994. What did you use to trace the PCB?

Sorry I was away and I lost a bit the thread here :) I do use DCD and DTR as "gpio" lines that I probe on my CDEV. For the 5v tolerance, I've read everything and the contrary, and to be sure and avoid long term braseros, I run my 32s only with 3.3v shifting were needed.

This is so cool, well done!

Finally back home, with the new LT2USB boards waiting for me! Can't wait to try them out.

I *think* the Rx line needs to be pulled, you can have a look at my airtalk board in the other thread, it communicates with an esp and is quite stable. I can also paste the schematic here but I can do it when I get off the train this night.

Very cool! When I'm back I'm going to try this asap, I also have a fresh batch of fixed LT2USB waiting for me.

Super! I can send you one of the prototypes when I finish mounting it, but it will take a couple weeks as I will be travelling :)

I had a look in the Designing Cards book, and indeed there is a selector in hardware. I think there is a control panel that selects if to use the internal or external port?

I Need to check the docs, I think it is disabled in software, there is a way to switch between the two but I don't remember right now.

Cool thanks! In theory my board also signals that the modem is installed (if I did it correctly!), so it should work the same.

No worries :)

thanks!!

yes! I'm planning to migrate all my stuff there.
