menu you can do some very nice things.
The first menu item is the most exciting one. It says RAM manager and you can add additional RAM to your VIC-20. As stated before the standard RAM amount is just 3,5 Kbyte, but you can go up to 512 Kbyte!! But there is more. You get another 512 Kbytes where you can put programs in you use often that you can then load from the menu directly. You also get a battery backupped real time clock. With the 'Basic Wedge' option you even get additional Jiffy DOS commands.
