You missed a few revs … Rev 3.9: First 2 layer board, dealer demo only (mine) Rev 4.5: Pull-up on U605 to support certain accelerator cars with the Signetics buffer chip. Kickstart 1.3 ROM is used. Rev 6.0: New layout for 1 meg ram chips Rev 6.1: Fix to clean up ram-retention by adding a reset IC. Agnus 8372 used. Rev 6.2: Fix to get certain expansion boards to work correctly with 256kx4 drams and Agnus 8372.
