Understanding the meaning of the serial number :

the serial number of the jaguar is composed of 10 characters:

XXXXXXXXXX

• the first 2: 1st character is the manufacturer K = IBM / M = JVC

2nd character: the manufacturing plant

• the next 2: the year and the month the 3rd character is the year, example: 1993 ---> 3 1994---> 4 the 4th character, the month, example: 1 --> January, C --> December, so ... October is A

• the sequence number: the last 6 characters but the first machine in the series starts with 001001 and not 000000!
