Quarter my original EOS of 300 Reward

I have 300 original EOS and am on a chromebook... fallback method (for chromebook) (work around) not making sense to me.. someone mentioned using scatter back when -should've done this a long time ago.
Anyways -Anyone with a trusted solution to convert the tokens for me can have quarter (75 eos) as reward.
Let me know. 
thanks
