Re: IIc Manufacture date based on serial number?

[A2Aviator <a2aviator@gmail.com>]

The motherboard chips are not a totally true sign because it was not
uncommon back then either, to have old stock depending on supply
channel used. While an OEM might do first in first out with their
inventory, they still may have procured from a different vendor and
that vendor might not have sold as many or whatever such conditions
were.

The motherboard has 4 digit number that consists of the week/year of
manufacture.
The injected plastic parts also have a time/date stamp dial embedded
in them.

The serial numbers on the //c were obfuscated, and after about the
millionth //e they went to some obfuscated system on there as well.

A recent issue with Gene Roddenberry's (purported) Mac, that the
'auction house' called it a Mac Plus, but it was not.  They
automatically assumed that since the serial number ended in M0001 that
it was the "first" Mac. Since the picture has it with an 800K drive,
perhaps it's a Macintosh front end, with a Mac Plus board in it, or
it's a 512Ke upgrade, or whatever, or that 800K drive functions
perfectly as a 400K drive as well. But M0001 is the model # of the
"Macintosh", and "Macintosh 128K". The 512 is M0001W while the Mac
Plus is M0001A.

Perhaps I should finish the user submittable database serial #
registry that I started and open that up so that folks can put in
serial numbers and then we can start forming the chronology of them
based on facts garnered from within the system. We already know that
they were manufactured either in California, Singapore, Australia or
Ireland.
