Clock, Zorro slots, Video slot, more RAM onboard ... even 020 model (2500?)
Had a clock with my spirit board, didn't need zorro slots since I had the side expansion slot, the spirit ram board I believe came with a clock and 2 megs of ram, also had put in a mod to make it go to half brite mode. Man I wish my wife didn't accidently throw out my A1000 when we moved, it was my hottest machine. Also had a 68030 Accelerator that plugged right into the 68000 slot.
But you are right on the video slot, because come to think of it my A2000 had the video toaster.
