Hi!
<--- snip --->
It is mildly difficult to find 20Mhz. Z80 chips in a 0.6" 40-pin
DIP package. There's a Chinese supplier on eBay who has
them from time to time and they can perhaps be special-ordered
from Digi-Key or Mouser.
Future Electronics apparently has them in stock. The catalog
number is Z84C0020PEG.

IIRC, from prior discussion, they need to be Z80B, but to be sure
you should confer with Alex for that information.
