That's great Witchy,
You could try increasing to a 10V input, many have found that this is a good compromise.
If you want to stick with the 8.5 V, I suggest changing R11 to a 2k2 Ohm resistor instead and that should give you the extra needed for the Reset circuit. However make sure D2 is working as the importance of D2 as a protection to the input at pin 13 becomes more important if you happen to use a 12V supply at some point in the future.
What components are missing from the other main board you mentioned?
