I got my A500 and a 1084S at the same time.
Added a 512k memory expansion, just to experience kick off better ;-) (AFAIR it had some extra sounds with more than the stock 512k mem). Plus I could now hear the wind when ejecting in Interceptor.
Edit: Forgot the Star LC24-10 printer ;-)
Then I got an external floppy, a sound sampler, and a new internal keyboard since my brother smashed the num key enter button by accident.... ;-)
