   As I recall when doing the Select-A-Bus conversion it required flashing the   
   BIOS   
   prior to swapping the riser out.  Flashing the BIOS and powering up without   
   installing   
   the matching riser caused the system to be unusable.  I still have my PC   
   Series 750   
   6886 but it's been many years since I've done a lot of circuit board swapping   
   on   
   those systems.   
      
   It's possible the planar you are using is unsupported or there is a   
   solder/component   
   issue on the board after all these years. When I started my PC 750 up back   
   around   
   2017 after a very long slumber it was exceptionally glitchy.  A bake in the   
   oven to   
   reflow the solder seemed to fix it.
