[sdiy] Frozen TR-808

[epk]

Hey Florian,

I tried sending din sync to it with the int/ext switch in either  
position but there was no change.  No Din Sync is output from the  
808, although that doesn't surprise me since none of the other  
controls are responsive.  Also the interrupt clock and CPU clock  
appear correct when scoped.

Thanks!
