My A1000 has the serial number XM 2000235.

The motherboard is a rev. 6 with a tin ground plane, as opposed to copper.

I have two A1000's (both acquired via fleaBay over the past couple of years). Thing is, is that the serial number is printed on the case, true, but there's no telling if the components are original or swapped from other systems (thirty-five or so years is a lot of time passed).

Mine are both NTSC. I'll check the serial numbers this evening and post them soon.

Allow me to add to the confusion -- here are my 3 A1000s:

XM1127283, NTSC, piggybacked Rev. 6 mainboard, PSU from Sept 1985
XM1145464, NTSC, piggybacked Rev. 6 mainboard, PSU from Oct 1985
XM1188378, NTSC, piggybacked Rev. A mainboard, PSU from Febr 1986

The earliest one from Sept. 1985 is guaranteed to be 100% genuine, as I personally imported it from the US shortly after its release, complete with matching A1080 NTSC monitor. It cost me an arm and a leg, but I took pride in being one of the first Amiga owners in Holland. Even Commodore Netherlands didn't have one yet.

I eventually added Kickstart 1.3 in ROM by removing the daughterboard, moving a chip or two, (un)cutting a couple of jumpers, removing the 2 bootroms and adding 4 EPROMs 27C512. I also did the obligatory PAL conversion hack by swapping the Agnus and changing the 28.6363 MHz clock oscillator to 28.375 MHz.

Commodore performed a very basic NTSC to PAL hack in their early PAL machines, without actually swapping the clock oscillator. They only installed a 8367 Agnus and reconfigured the MC1377 by changing a few of its surrounding passive components. Yet the composite video output of those early "PAL" machines was only in B/W, as the clock oscillator remained 28.6363MHz. The NTSC color burst frequency of 3.58MHz was obviously derived by dividing 28.6363 by 8.

My 3 machines have all been fitted with Amiga "checkmark" badges. I wonder if any A1000 has ever left the factory carrying the ultra rare boing ball badge. I dare to believe that any occasional boing ball badged A1000 out there was rebranded by its owner.

Posting the production date of your PSU might be helpful in solving the puzzle.

I'll remember to get that and board rev next time I open mine up, I just had it apart to replace the floppy drive too, and I saw the rev number, and was like I need to write that down somewhere, and boom, got so excited that my 1000 booted to Workbench I assembled most of it.

Finally got the old gal dug out of the closet and running again..

SN: XM1173566
BTW - the case does have the signatures

Motherboard: Rev A 327049-01

Daughterboard and Motherboard have matching stickers..
Daughterboard: Y8AA2072646
Motherboard: Y8AA1071869

Power supply: 130569SXD (Viking Group) SN: 084452 86-1

I purchased this new from an authorized dealer on 16-Jun-1987.
At some point, I installed an ICD AdIDE w/Quantum 105Mb 3.5" HDD and an ICD AdSpeed

There is something installed in the U7N CIA chip socket with two jumpers: DIS (open) and SFT (closed)
**After originally posting this, I figured out this is the ICD Shuffleboard that allows you to make the external 3.5" floppy DF0: when you remove the internal drive to mount the HDD.
