The DEC ones are easy, they have reddish/purple handles and the Mxxx number
on them (sometimes 3 digits, sometimes 4 digits). The Green ones are
usually part of the core stacks.

Third party boards had a variety of colors, but the most common I've seen
have been either white or yellow.

Most boards include a model number in the solder mask (either side).

Most have a company name next to a copyright string (again often on the
solder mask or as copper traces)
