No its not the way to do it on an old CoCo Zack !!!!!!
If he has an old CoCo machine, all he needs to do is open the case
, check for an empty sockets, see if it's a 24 pin or 28 pin. Order
that 24 or 28 pin EBC from mailorder or conntact a local Radio Shack
and ask if National Parts still has any in stock.

Now for the easy part. install the chip (make sure not to install it backwards)
and presto !!!! it should power up in extended basic mode.

Zack this is not intended as a flame. I would hate to see this guy
destroy his computer and blame it all on you.
