Check out the pdp11-field-guide, there are a number of non-DEC boards listed there (check my web site). If they don't have one you are familiar with, please send me the information about it including manufacturer, part number, what it does and any supporting evidence (pointers to documents, etc) and I'll include the information in a future edit of the file...
