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.
