yet free I/O chips from the legendary Jon Titus. He's not on our list but
he is good about replying to email. Info is below.
Do you know anyone who might like some old I/O and controller chips?
I uncovered a drawer with a mix of 8080/8085, Z-80, and 6502-type I/O
chips and would gladly mail them to someone who could use them. If I can't
find a home, they go in the trash. Feel free to pass this message on to
your vintage-computer colleagues.
