Finally, I recall seeing an article where

library code.
I remember that one. It may have been an early issue of Byte. I
also wondered at the time if any speed was gained over just running
plain old x80 code.
IIRC, it was in the .01-centennial issue of Dr. Dobb's. I have a copy of
it somewhere, but there's no way I could find it without a lot of
effort.
Speaking of DDJ, I could still kick myself for passing up on some bound
versions of their early years, which I first saw at a local computer store
one time for around ten bucks each. (Computerland? I forget...) Seeing
them later the price had gone up 3-4 times that high. :-(
