Yeah I wish!! LOL. I opened up the one with two switches actually (one on the side of the floppy one in the back). It is definitely not a '040 board but it does seem peculiar. Besides the disgusting dirt and mouse droppings on the board the two switches are interconnected between the GARY chip, which is raised, and on the board between the M68000 and the ROM chip. According to the sticker, it is a KS1.3 Rev.5 and 512KB RAM. However, I do see A501 expansion ram board so maybe the sticker refers to an old setup. I didn't go any further because of the mouse droppings and I don't have an air blower ATM. More to come...
