If it helps, my A1000 has the following:
8367RD 1486S - Agnus
8364R4 06-86 - Paula
8362R6 5185S - Denise
What does yours have?
If anyone's interested, mine also has a DKB "Insider 1 Meg" board that plugs into the 68000's socket (with the 68000 itself relocated to this board).
I also have another board inside, mounted upside-down, with a single serial number on it of Y8AA2099391 - but I don't know what it is and don't really want to remove it in case I damage it. I assume it's a further RAM expansion?
My A1000 itself is made in Japan, with a serial number of XM5001480N. It has "Commodore Amiga 1000 Personal Computer" on the sticker underneath the case, so mine's a comparitively "recent" one. Is yours one of the original ones that just says "Amiga"?
