even if they're surface  mount, they shoudl be easy to
desolder/replace.   look for the 1488/1489 chips.  one is the serial
port receiver, one is the transmitter.  they're directly in harm's way
between the CIA bits (for control signals) and the paula (for TX/RX
data).  hopefully, that's all that's blown.  the chips ares quite
cheap.
