My guess is a 2MB chip and you switch between the 3 512KB ROM's... would have been nice if they also added a 1.2 ROM.
I take it's like with the dual ROM but with more leads to the switch."You need to have kickstart switcher device or you need solder cables with switch on module manually."
There do exist a few
42pin kickstart
switches but this is definitely not what this needs to operate.
Without a "kickstart switcher device" I wonder if it requires a A500 Rev8 motherboard or if pin 1 and 42 are to be outside the socket and Rev8 users need to bend out the pins.
