Getting in-the-groove of 6502 assembly takes time, but once there you 
can program about as fast as anything.  The idea is to take a few key 
constructs and be consistent. If you look at the source, you'll see how 
register usage and assignment are very similar throughout. Sort of like 
being a human compiler.  Think high level, type low level.

And of course you need the time retirement provides.  I have a notebook 
of ideas and code that stretches back a few years when I first started 
contemplating an object-oriented, multi-threaded language for the Apple 
II.  In a previous life I implemented floating point in hardware, so 
that part went surprisingly fast.  This summer my son spent some time 
with his mom, so I took advantage of a few quiet weeks to complete.  A 
geek vacation of sorts :-) (I'm sure Michael can attest with the 
development of AppleCrate II).
