Our recent discussion on delay routines spawns a new topic, "routines you'd never want to use and declined 8051 opcode suggestions"

Things like:

.delay:
. djnz sp,delay

or

.delay:
. acall delay

Or opcode suggestions like:

. rlc pc

Maybe someone can repost to circa 1980's opcode sheet that included classics like "Convert to Roman Numerals," "Backup Stretch Tape and Runaway" and "Circular shift stack contents"
