I need to journalize this transaction. Can someone please help

Traded in the cash register we purchased in January. Calculate the depreciation to
date ( 3/12 of a year, zero residual value and 5 year life using straight line). We received
$500 trade in for this cash register. We are buying new cash register with a list
price of $1,000 by issuing a note for 10% interest. Use the GAAP method
of accounting for the loss on the trade in. The new register (#2) will have no residual
value and be depreciated over a 5 year life.
