I agree that 5.2V should not be able to trigger the the crowbar but the clicking sound is very typical for an emergency shutdown in the PSU imho. The source might for example be over current or over voltage. In the Sony PSU both the 12V and 5V outputs together control the emergency shutdown. A...

Can it be the crowbar in the PSU which false triggers? This repair guide page 10 mentions the crowbar.

So. I solved this as well. A/UX is a new environment for me but I am used to quite a few variants of unix. There were a directory called mac in the root directory that caught my eye.  /mac/sys/Login System Folder/Preferences There were a file called Autologin which I renamed. The contents...

So I got A/UX running by fiddling a bit. Installed A/UX 3.0 and then 3.0.1.  It is running but I cannot get it to give me the login screen when starting up. I get thrown into the finder environment directly so there is no choice to select another session type like X11 or so. When I had 3.0...

I yesterday tried to install A/UX 3.0.1 from those ISO-images that are floating around on the net. But failed. Whenever it got to installing the actual A/UX it complained about "Cannot mount "/dev/dsk/c100/d0s0" - Invalid argument. But already earlier during the bootup phase and during disk...

It is 5V 1A /Mattis

Many thanks for the driver! Now my SE/30 is on the net running System 7.0.1 and Mosaic 1.0.3. /Mattis

I traded a Radius board for a Asante Maccon board for my SE/30 and now I need the drivers. I failed to find them through google. Anyone has them? Downloadable? /Mattis EDIT: Maybe I should have written diagnostics disk. So I could check that the card is found in the machine.

There is apparently a widespread misconception that LocalTalk is what we commonly know as asynchronous  serial communication. Well. It is not. LocalTalk is 230400 bps FM0 coded bit synchronous SDLC.   It is all described in this book Inside AppleTalk. Check Appendix A for more details. So just...

Good work Mactjaap! And a very nice matchbox as well! I still have the modern-HW-LocalTalk project sitting back in my mind but it won't happen in the near future unfortunately.

Yes. There seems to be a widespread misconception here that "serial is serial". Of course it is not just serial. There are different connectors, different voltage levels, different link protocols and different line encodings. As stated LocalTalk is SDLC/HDLC. But it is using FM0 line-encoding...

I did a quick write-up of my experience with MacIPPi and how to get it working. It is here.

Maybe not a commodity, sure. On the other hand the amount of people doings this kind of networking experiments are quite limited. I see these devices all time at Ebay. They are not directly selling quickly. Search for Dayna Etherprint for example. Not extremely high prices. I bought mine from...

Have you looked into what you could do with the PRU on the Beaglebone Black / Texas Sitara? A really interesting thing. I haven't played with it myself but a guy made a MFM disk emulator based on the PRU coprocessor. It reads the and writes the 5 mbit/s data stream in realtime. I have tested the...

BTW here is the a pdf of the book "Inside AppleTalk" that probably cover all of what you need to know on AppleTalk and LocalTalk. Way back as a student I bought this book for hard earned money. I had an idea of a project (much like the macippi but using a PC) but it never materialized. I do...

I am not 100% sure what mactjaap want to do but I would assume it is to get rid of at least the LocalTalk to EtherTalk bridge  and maybe the LocalTalk adapter, but still connect to the OrangePi over AppleTalk. Not using PPP over async serial IO. I understand that since one of the beauties of the...

Well. It took me a while to get a grip of how Apple stores files and how to get them on to the machine. I am used to Linux and MacOS X and have never heard of AppleDouble. So it took some time to come up with a solution to first use stuffit expand to repack files into Macbin and then have them...

Hello mactjaap and everyone else! I can now confirm that the new image is much better. It boots fine. It includes the magcipgw and netatalk daemons. This far I have only tested that I can reach the orangepione AFS server over my localtalk which is connected to a Dayna Etherprint Mini. It mounts...

**** Sorry long post ****** I just tried the Macippi image for OrangePi and was unable to get it to work. I downloaded the image and unpacked it (Armbian_5.07_Orangepih3_Debian_jessie_4.6.0-rc1.raw) mentioned on the macip.net webpage and dd:ed it to a SD card. The machine booted up. No screen...
