Perhaps some of you remember my mysterious error with my SAM.
It worked (aprantly) OK, until it started scrolling things
on the screen and moving sprites etc. Either it didn't scroll
propperly or it left a trail of the sprite, etc.

I also mentioned that I had checked everything; ASIC, RAM, 
surrounding logic, THE WORKS. My only theory was that it could be
that one or more instrucions inside the Z80B was corrupted. So 
(after 4 months of nagging) I got a replacement (I was a bit
surprised here as it came together with my copy of Format and
absolutely free of charge) the other day, and yesterday, I finally
found the time to solder on a socket and try it out. 

AND...it worked! Horray!

Has anyone got any ideas how a defect Z80 could come out from
production, or how it could have been corrupted on board?
