Notes on Data General product numbers:
Data General gave definitive part numbers for each product it created.
The part numbers are usually located on small labels on each board, and
have the format of
005-xxxxx-yy
where 005 indicates that this is a product number,
xxxxxx is the specific product, and
yy is the product revision number.
In later systems (1980s) the labels sometimes had two 005 numbers on the
label: a "T" (Type) number and an "A" (Assembly) number. This was done
because a specific PCB, or "Assembly", could actually be used for
different products depending upon what chips or PROMs were stuffed on
the PCB. In these cases the T 005 number would indicate what specific
options were supported by that specific PCB.
On PCBs the 005-xxxxxx-yy part number usually exists on a label attached
to the 15"x15" board stiffener (the side opposite the finger edge
connectors). This PCB label might look something like this (note that
this is just an example):
T 005-001322-03 A 005-001367-04
In these situations the important number is the "T" (type) number rather
than the "A" (assembly) number since it uniquely identifies the
particular product and its capability/function.
The "107-xxxxxx-yy" type number is a circuit board "artwork" number, not
a Data General product number. Similar to an "assembly", a single
107-xxxxxx-yy circuit board artwork may actually be used by multiple
005-xxxxxx-yy parts.
Therefore, the part number is the primary (PCB) reference to be used
because a single 107-xxxxxx-yy circuit board artwork may actually be
used by multiple 005-xxxxxx-yy parts.
Schematics are identified with an 001-xxxxxx-yy part number, and may not
even have its corresponding "artwork" number listed on the schematic(!).
Unfortunately, I do not know of an official cross-reference between
product numbers and artwork numbers.
