Yes, but does it still have that silly requirement that you waste 20% of every 
256 byte page of ram with long jump tables because it can't do a conditional 
jump with more than a signed 8 bit offset?  I always considered that chip as 
being terminally broken by design just because of that.  Even the lowly RCA 
1802, with its subroutines for calls and returns beat the daylights out of 
the Z-80 and its housekeeping trash.  The 6809 was indeed a better idea.
