You should at least inspect it. If it has any leakage at all replace. You should replace anyway, when you have chance. Amazing how the hardware has held up. WP-2s, Cambridge Z88, NC-100/200 are hard to keep working with the memory preserved and coin cells undrained. The Model T's have a much more solid RAM-based memory design that has held up incredibly well. Best of all worlds, recharge-in-place long term memory keep-alive. -- John.
