Wikimedia Commons has a pic of a 1979 XC68000L:

After a USENET posting pointed me at them, I browsed the Sunnyvale
Patent Library to bring home the patents for the Motorola 68000. They
include a full listing of the entire microcode! I ended up copying it,
taping the sheets together to reconstitute Nick Tredennick's
large-format "hardware flowcharts", and hanging them in the hallway near
my office at Sun. Fascinating!
