how old is my mpc?

is it possible to find out when my mpc was made? the previous owner ripped off the serial number sticker so would it be possible to determine from internal parts?

My floppy drive has a date written on it in pencil, but otherwise it is quite difficult without the serial number.

What OS version does it say on the boot screen.

Also, next to the power connector there may be some letter codes like "B" or "K" or similar.

Let us all know.

Rohan.
