DG used in-house part numbers, very much like IBM and HP did. But I
haven't come across an equivalence list, so if you don't have the
schematics, you're lost. There is the DG Components Guide, but you must
be clever in figuring out the corresponding SN or whatever standard part
number.

It's not that bad. The DG Components Guide helps a lot. Beside that,
many boards have numerous components with standard numbers. Only a few
are tricky because high drive strength or high speed is required.
