Don't laugh - simple ][e questions

Hi chaps... I just picked up an Apple ][e complete with DuoDisk box and orange monitor. Great thing is it also has also the DOS 3.3 manuals and disks and bits and pieces in their original packaging! All i paid for was the petrol (yeah, i'm in England!) to go over and pick it up. Opening up the case reveals that it has a number of cards plugged in including a memory expansion card - does anyone know what size RAM this gives me? how can i check (forgive me for i have not RTFM yet!). It seems to work fine, so my big question is can i use any old 5 1/4" disks in it? is it capable of formatting any old 5 1/4" disks? I ask for two reasons: 1) so i can make back-up copies of the DOS 3.3 disks and 2) so i can save stuff. TIA...Nick. -- Nick Challoner nickc(a)ladyland.demon.co.uk Aviation photographs at: http://www.ladyland.demon.co.uk "Bother" said Pooh, as he deleted his root directory.
