I am trying to share files between my Power Macintosh 8600 and my 512Ke via a serial cable connected to the "modem" ports of both machines. (The PM 8600 is 8 pin, the 512Ke uses RS232. I am using a printer cable with each type of connection on one end.) I have been in contact with Niles Mitchel, the guy that gets his 512Ke to recieve Pictures from his iPhone and such. He sent me a special boot disk that has System 4, Finder 5.5 Easyshare and a few other cool apps. It all seems to work beautifully and as far as I'm aware, the 512Ke should be sharing it's files perfectly. However, when I have both machines connected in the way I have mentioned, only one machine will boot at a time. While one has booted, the other will refuse to make the appropriate Apple "Ding/Bwaaaam" it is supposed to. As soon as one machine shuts down, the other springs to life. When the cable is not connected, both work perfectly every time. The PM 8600 is running Mac OS 9.1 (and Appletalk) and the 512Ke is running System 4 and Finder 5.5 (and Easyshare, giving it Appletalk capabilities) Any ideas, is this common?
