[sdiy] TR-909 reset pin on PSU

[epk]

Hey all,

I've got a TR-909 that I'm migrating to a custom case/panel and  
external PSU.  The 909 has a reset pin on the PSU board that goes to  
the switch board which is throwing me for a loop.  I don't really  
understand what happens with this pin, and more importantly how to  
spoof the functionality with an external PSU that doesn't have a  
reset.  Is there an easy way to do this?

Here's a pic of the PSU board schematic:
