I've did some digging, too.
for the corsair II, it looks like it's a microprocessor, and unless you have
the code,or can read it from a known good chip, you're sunk.
here's the data sheet:

you can find the part, "IF" you're willing to spend the $200 min line.
the corsair I, the MK50398N is a bit easier to find. It's just a 'counter on a
chip' and there's a place in England that has them in stock for a mere $150 +
shipping.
Like jerry mentioned, I'd look into the receiver counter from AADE and see if
you couldn't the counter to use the ten tec original corsair display
