I've got one, mines the one in the Big Book of Amiga Hardware. There are only 2 Zorro 1 slots, which are Zorro 2 compatable. The one board is a hard drive controller and the other is a Ram card. It will take any half length zorro card, so you could put whatever you wanted in it. The original drive controller is not autoboot and requires special startup sequence. It's heavy and the $40-$70 dollar shipping charge seems right.
