Ok, is there some trick to identifing pdp8/a quad
height boards? Or maybe
most of these boards are not standard DEC issue... I have a lot of boards
that have wierd markings on the green or grey handles, all have VG DS on
two sets of handles, but one of those is covered with a round sticker with
a 3 digit number on it... very strange...
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)
