After 4 fried ramps 1.4 boards, I decided to shell out the extra cash and buy a Rambo 1.2d.
I discovered I am one of the unlucky ones with a missing bootloader (expected no less with my luck)
My avrisp mkII Will be in the mail tomorrow, but I'll be up all night and use this time to learn something new hopefully!

I've been reading up on using an arduino uno or mega as isp, but I can't find anywhere that shows how to use either to burn a new bootloader onto my
Rambo 1.2d
I see some people saying they were able to do this, but no links are posted and no explanation is given on how.

Please can anyone help me?

anyone? I just need to know how to directly connect the Rambo isp pins to an arduino so I can burn the bootloader.
