Doubt about macintosh 128 serial number and its case

[etegar]

Hello,

I,m thinking about purchase an old Macintosh 128K, M0001P (international 220v), with serial number F40602VM001.
The board is correct, a 820-0086-C model with a CPU labeled GN78418 and memories replaced.
So this would be a very early Mac, but my doubt is that the back case shows "Macintosh 128K" instead of the expected "Macintosh" according to the serial date that it was born (6th week of 1984, Fremont).
Is anything wrong here?

Many thanks.
Eduard

The 128k badge would have been used if the Mac was sold after the 512k was introduced so that serial doesn’t quite sound like it matches up with the case.

Doesn't match up.

I can forgive a motherboard and/or analog board swap but, assuming the front has no text of 'Macintosh', the rear case doesn't match the front serial number.

Also, quite a few ICs and the two DB9 serial port connectors have much later manufactured dates (1984 week 14 to 20).

Thanks for the detailed information.
I was thinking too that the reason would be for the "P" of the M0001P model, which might affect the final assembly production for the macs that were sent abroad, and that reason explains some kind of delay and the final rear case design.

Without pulling mine out to check, IIRC the rear bucket isn't numbered on these, and the only SN is on the front label under the edge of the screen.

This computer certainly raises some questions for me. I wonder if perhaps the original rear bucket was badly yellowed or otherwise damaged and someone swapped it for a later "128K" one.

I do know that my 17th week of 84 example by SN/20th week by the newest IC on the lobo says "Macintosh."
