Hi Roland, Thanks! Yes, this has been discussed before. This document is very useful however, since it puts everything into one place, and I bet Timothy has it marked for future reference already. The current consensus is that it would be very nice to have (but not absolutely essential, since other PC hardware doesn't have it either), but as with every part of this design, it depends on the amount of available gates and/or chip surface whether it can be implemented. We will have to see how it goes.
