No it wont have pass through for a 68000. It sits in the 68000 socket and an IDE header will be present between the pins of the connection with no place to put a 68000 on what is a pretty small card. This is an upgrade designed to replace the 68000 with something much, much better. If you want to carry on using old, badly written software that doesn't work on fast Amiga's then maybe the V500 isn't the accelerator for you.
