I forgot to mention we must also use our own devices also located on the floppy
disk, E.G. /fd0/dev/tty0, /fd0/dev/ttyS0, /fd0/dev/ttyS1 instead of /dev/tty0,
/dev/ttyS0, and /dev/ttyS1 on the host OS. How could I get 3 qemu SDL windows
to pop up at once, 1 of the terminals running on /fd0/dev/tty0, 1 on
/fd0/dev/ttyS0, and one on /fd0/dev/ttyS1 and they would all be tied together
by the guest OS?

IIUC you'll want to use the -serial option. I.e.
kvm -serial stdio ... image.img
Will give you ttyS0 in the terminal from which you called kvm. Or, you can
do
kvm -serial tcp:localhost:2222,server ... image.img
and then
telnet localhost 2222
from another terminal, to get serial port redirected through telnet.
