My first Amiga was an A600 too. I got it in 1993 short before Commodore went under. It was a blow out sale at Karstadt for 299 DM. The first Softwar eI got was Wingcommander and I got it over 2 Months in advance. Yes I completed Wingcommander on a bog standard A600 playing from floppy.
The first expansions I got was an external secondary drive and a 1MB Chip-RAM expansion at 149 DM each.
Those were the days ;-)
