@ Marketing system numbering scheme
@ Information system numbering scheme
These numbers, along with Prime type numbers, are explained and listed
in this subsection.
1.6.1 MARKETING SYSTEM NUMBERING SCHEME
Prime Marketing uses model numbers to identify an entire system
configuration. For example, 550II-HMB refers to a 550-II CPU with
1/2Mb memory and a hard copy system console. Prime Manufacturing and
Customer Service Logistics use part numbers instead of model numbers.
One Marketing model number can be broken down into many Manufacturing
part numbers. For example, 550I1I-HMB identifies the same equipment as
the part numbers for each of the following:
@ CPU — 2253-902, 2278-901, 2279-901
e Tophats - ESA2495-903
@ Power supply - 1045-901
@ Cabinet ~— 7550-901
e VCP - 2265-901
@ Memory - 12128-E6
@e Terminal - TTY3754-001
The customer's sales order identifies equipment using Marketing model
numbers. The packing slip, shipped with the equipment from the Prime
factory, uses Manufacturing part numbers. Therfore, a working
knowledge of the Marketing model number scheme is necessary to be able
to check the sales order against the packing slip.
The Marketing model numbers assigned to the 50 Series systems consist
of six alphanumeric characters. Each character and character position
has a special significance. To provide an example, the characters A,
B, C, D, E, and F are used to indicate the meaning of each character
in the 50 Series model numbers as follows:
ABC- DEF
070-C l- 8
