I don't know much about the ethernet cards sold by companies other than Apple for A/UX machines, but I do know that the Rev. K or earlier NuBus cards do not work well in a Mac IIci. I had a problem with a Rev. K board and was told by the 1-800 cust. support people that the older boards have problems with the IIci. I got a new board, a Rev. M board, and that helped out. I have had other problems with my machine though (I believe related to bad memory), so I don't now for sure how much of my troubles were related to the ethernet board, but I do know that my machine stopped locking up after I got the new board (a major improvement in functionality :-). I believe that at this point, no one should have to worry about the older Rev. K boards because I think that Apple has been distributing the new boards for well over 6 months now. I just thought I should mention it in case someone gets a Rev K or earlier board for their Mac IIci. For those who are interested, the specific problem that I had when using the Rev. K board was that at random times (seemingly related to network usage), my machine would appear to lock up. It was actually still working though. If I moved the mouse, the cursor would move, but it would only do so every 20 to 30 seconds or so. I could also type characters and every 20 to 30 seconds, they would apear on the screen. Basically, it seemed like the ethernet board was locking up the bus for 20 to 30 seconds at a time, and then giving the CPU about a half of a second to do something before taking the bus again. The only effective way to get out of this situation was to reboot the machine. Sometimes I couldn't even reboot the machine because of a hardware problem that wouldn't let the machine boot up to MacOS even. I believe now that this is related to bad memory. Between the Rev. K ethernet board, the possible bad memory and software problems with A/UX, this machine has pretty much been a lemon. I suppose that if I am right about the memory being the cause of my current problems, then the machine will no longer be a lemon, but right now, I don't trust it very much.
