Data General Product Number Notes
Data General utilized a systematic code to uniquely identify each individual document or part. This "Product Number" is typically an 11-digit number which has a format similar to this example:
| Prefix | Item Number | Suffix |
|---|---|---|
| 001- | 000088- | 15 |
The Prefix is a three (3) digit number that indicates the general class of a document or part. In the example above the '001' prefix indicates that this number refers to a schematic.
The Item Number is a six (6) digit number that uniquely identifies the particular item. The '000088' in the example indicates a Nova 1200 CPU schematic.
The Suffix is a two (2) digit number indicating the revision level. The '15' in the example indicates the 15th revision of the schematic.
The following table lists common Prefix codes and classes:
| Prefix | Description |
|---|---|
| 001 | Schematics |
| 008 | Wire lists for cables, plugs and interconnection wiring |
| 010 | Installation data sheets and configuration drawings |
| 014 | Technical reference and programming manuals |
| 015 | Technical manuals |
| 016 | Illustrated Parts List |
| 052 | Student Guides (training) |
| 077 | Firmware |
| 100 | PROMs |
| 107 | PCB artwork |
| FAB | Field (Engineering) Alert Bulletin |
| TIB | Technical Information Bulletin |
| FE and FE_Notes | internal Field Engineering notes |
The Wild Hare archives reflect the DG product numbering scheme whenever possible. Document filenames start with the corresponding Data General product number and follow with a text description or title. Different source copies of the same document are all preserved, and are given a 3-digit numeric suffix (i.e. "000", "001", "002", etc.) for uniqueness. Poor quality originals or copies of documents are indicated with a '.c' suffix, and partial documents are indicated with a '.p' suffix.
