I would like it know if there is >a way i can mount that floppy under linux? for use with E/L Well, you can't put the floppy in a PC floppy drive due to the variable-speed drive old Macs like yours used to use. If you could find some way to hook up the Mac physical drive to your PC and then write a kernel device driver for it then maybe you could... :-) >Also Id like to use the old mac as a dumb terminal >I need terminal software for this old beast. This I have done. I have a Mac Classic on the desk next to me acting as a serial terminal on my PC. I'm using an in-house terminal program called Fawn II, but any terminal program should work. Here are the relevant lines from my various configuration files: /etc/inittab: S1:246:respawn:/sbin/getty ttyS1 DT9600 vt100 /etc/gettydefs: # 9600 baud Dumb Terminal entry DT9600# B9600 CS8 CLOCAL # B9600 SANE -ISTRIP CLOCAL #Login: #DT9600 /etc/rc.d/rc.serial: stty clocal < /dev/ttyS1 I found this last to be necessary, despite the gettydefs entry. Without this entry I could type commands and things on the Mac, but couldn't see anything, although by using redirection I knew the commands were working. >I tried plugging a null modem cable into the serial port and >the machine wont boot :< it boots fine when i take the cable out. You mean the Mac won't boot? Weird. Can't help there. Sounds like your null modem cable is confusing it for some reason. Do you have RTS/CTS lines correctly looped back? I know that that can confuse some PCs. Having a Mac as a serial terminal is very useful... if your console locks up for some reason it means you can still log in and shutdown cleanly rather than hitting the Big Red Switch. Tim.
