In 1991 I had A2000C, 20MB HDD, 3MB RAM, XT-Bridgeboard, 2 internal FDD 3.5", one internal 5.25", one external 5.25", NecMultisync3D, Matrix printer, etc...
I never really used the bridgeboard, I could do everything + more on the AOS side. I sold the A2000 around 1994, without monitor, for 5000FIM (833eur), for video production needs.
