Megadrive pins while in reset

Post by Alan » Sun Oct 31, 2010 10:42 pm

Hi all,

Does anybody know the state of the address, data and control lines of the megadrive while it is being held in reset (hard and/or soft).
I'm hoping they are tri-state but would like someone to confirm.

Regards.

Databus is 3state and strobes are held high, IIRC... no idea about address bus...
