Hello!
Looking for one (or a couple) HD10125 chips. They are used in the clock
circuit on Zaxxon and Super Zaxxon. I haven't been able to find one
from any of my sources.
Will consider junker boards to pull the part from too!

Part number sounds like ECL -=> big $$$ chip!
....yep... ECL -> TTL converter... donkey kong uses this in it's clock
circuit too.
ON Semi still makes a lot of ECL parts.
Allied carries (MC)10125 for $4.28 each.
