@Satancillo , esta es una parte de la explicación que hay en SMSPower, dónde hay o había una persona haciendo con la Master System lo mismo que hace
@kusfo79 aquí con la MD.
Sega used the same basic serial number format (with some minor variations) on all of their consoles from the Master System to the Saturn. The first three digits ie "XYZ" (which I'll refer to as the batch number) denote the manufacturer, year of assembly, and production run. For example;
X: This was the manufacturers code. In 1986 1 (Japan), 3 (Taiwan), 5 (Taiwan), and 8 (Japan) manufactured SMS. These would occasionally get reset or reassigned as the manufacturers changed.
Y: This was the last digit of the year of assembly. ie "6" = 1986, "1"= 1991 etc.
Z: This was the production run, generally with different models being simultaneously manufactured starting in different codes. At first they usually started in 1, 5, or 8. When they ran out of numbers they started using upper case letters, then lower case letters. This system was also used by Mega Drive, with letters reserved for each model. After running out of letters the system was simplified in 1990/1991 (depending on manufacturer). With them adding an extra digit, and just starting at 0. SMSII (and a small number of very late SMS1s) use this simplified format.
