I searched on Google, but the only serial number decoding website I was able to find spat out the information I linked to at the beginning of my post (It was the 803rd made in Fremont California in the 41st week of 1984, which puts it around a month after the 512k came out (the week of October 7th is supposedly when it was made, while the 512k came out on September 10th. Low End Mac at least said the 512k started production in 1984, but yet my on my Mac 128k both halves of the outer case are yellowed the exact same amount, which is very little considering it is now officially 26 years old-and the logic board and rear bucket both say they're original 128k parts based on a comparison of what's on my logic board to what an original 128k would have); but yet it was supposedly made well after the 512k came online. I am wondering, did they use up the remaining stock of original 128k cases and logic boards even after the 128k was branded the 128k? If you could provide links to the other two serial number decoding websites you mentioned. I used the one here: "http://macfaq.org/serial.html".

Thank you so much for helping me out!
