Mac Classic and Plus help

[bbmike]

Hey

I just got 2 mac classics and 2 mac plus's and a bunch of mice and keyboards

i know nothing about them or mac in general,

i am really interested in these, but need some help

 

1 of the computers, when you turn it on just has a black and white vertical striped screen

 

2 of the computers turn on, and go to a blank desktop with a flashing floppy disc icon in the middle

 

and the other classic turns on and seems to work fine.

______

starting with the working classic,

 

where can i go to find out how to use this OS which 7.1

 

 

also when it turns on there is a picture of a cartoon bear that comes up while loading, and the disk? icon has the name of a person in this case "harley", how can i reinstall a clean OS?

 

_____

on the 2 mac plus's, the keybord has like a telephone jack looking connector, i didn't get those, so where can i obtain those?

 

I have tried a bunch of floppy's in the running classic and it has to initialize all of them, some fail, and some work, but after i download the files for the OS how do i get them from my windows pc to the mac?

 

thank you for any help
