How about replacing an esixting part that had emulation (on an
emulator that won't single-step) and OTP support, with a new
"improved" chip that has no emulation, no OTP, but they will give you
a real deal on mask charges?

Like the Z-280 rev H cache bug?

At one point, the company I worked for was the largest purchaser of
Z-80 parts in the world.  Zilog's support still sucked.
