 I am toying with the idea of upgrading my 520ST.
 If I am going to go to the trouble of installing a 
 Ram upgrade however, I don't just want to go to a meg.
 Are there any kits out there that will let me upgrade
 a 520 ST to 2 meg ? Also if I could upgrade to this kind
 of memory capacity, is there anything available software 
 wise that will allow me to do multitasking or at least 
 load several programs at once and toggle between them for
 execution ?
 (i.e. for music applications: load up a sequencer 
                                       a patch editor
                                   and a word processor
then if I am running a sequence, have the ability to stop
a sequence, toggle over to the patch editor, tweak a patch from
the patch editor prog, maybe make a note in a session log in my
word processer then toggle back to the sequencer and continue
execution without having to load and reload all of these programs.)
Thanx for your help,
