Commodore A4000T serials

[bitman]

I'm trying to estimate the number of Commodore Amiga 4000T produced (not the AT models), by collecting the serials. There's a thread here where I enter the serials. You can post your serial here or post it directly in the thread at BBoAH.

Is it normal to hav a CBM motherboard in the AT version?

My 4000T skin is an AT but it's heart, mind and soul is C= . My motherboard is a C= 4000T Rev 2 "Ser. No. 2  1-10-94" (handwritten sticker). It's the yellow silkscreen with a Buster 11 in a socket as well as some small chips (pals/gals?) that the Rev 4 has surface mounted. The motherboard works but I lose the Zorro boards after a reset when it warms up. The Buster socket is visibly bulging (never had the problem with a quality 3000 socket) and it probably needs a cap job but I haven't gotten around to it. I did replace the AT power supply so that wasn't it. I've tried to take pictures before with a cheap camera but they didn't come out very well (fuzzy and poor lighting).

Your mobo is probably the same as mine:

Yellow motherboards - I see no yellow motherboards? My (green) motherboard has all the C= marks and also original Commodore ROMS and sits in the Original CBM case. Mine is pretty much identical to the motheboard in the article you link to.

Difference could be that mine is assembeld in germany for EU market.

Check your ROMS - the rev4 version from AT - has a ROM that says Amiga 1995: http://www.bigbookofamigahardware.com/bboah/media/download_photos/a4000tmb_rev4_4.jpg

You can also Check Ramsey  on the AT version it also says Amiga 1995.

If you have Commodore ROMS 1994 - it's probably a CBM motherboard.

[bitman]

Sounds like a Commodore to me. Will check my Ramsey later (if I can see it without removing the daugtherboard)

EDIT: Just checked mine it's also a Commodore Ramsey.

So only difference between some AT and CBM produced is the case

Matt_H;732081]There were only a few chips that Amiga Technologies produced. Most of the chips in the machines they built were Commodore parts that were still kicking around. They also never updated the silkscreening on the 4000T boards - they all say Commodore.

Nice info to have about the motherboards

[bitman]

Intersting low serial number - the Picture in BBoAH has serialnumber 9000001 - judging from that, yours is number 2 produced.
 
Anybody with high numbers? Mine is 200000073 (from the German assembly line)

My CBM A4000T is serial number:
 
9000002

I've updated it with photos of mine - if you're looking for specific shots, just say which and I'll take some.

[bitman]

Took a few quick shots - if you need higher res. I'll post them to big book...

Until now I've found 3 CBM serials in total -but it can't be that rare. If anybody is following a foreign speaking forum (french, Hungarian, german etc.) - could you please post a note about this thread?

[bitman]

Highest serial received so far is 0093, so conclusion is we ares till below 100 produced.

[bitman]

Received a bunch of serials (4 from Germany) - and the status is:

Highest unitnumber produced by Commodore in Germany: 131
Highest unitnumber produced by Commodore in USA: 43

If we don't find any higher serialnumbers (unit numbers) - conclusion still is that under 200 was produced and very few is known to exists today (10 in total).

It's very likely that we havn't found all owners yet - but we keep looking.

[bitman]

1475..., that dosn't sound like a CBM serial number.
