A4000 Rev B Bare PCB board?
« on: May 27, 2015, 01:55:38 AM »
Were these bare A4000 Rev B desktop PCB boards available at some point  in time?  I purchased one the other day and this actually might be  "rare" as the seller described but I am skeptical.  It's a wall hanger  (and I'll frame it with a decent presentation) but you guys must know  how common these are.

That's one way to get a board with no battery damage!  :lol:  Congrats, don't know how rare, but definitely a nice find!

I recall a batch of 4000T blank PCBs in circulation some years ago, but never a desktop 4000. Congrats! Enjoy it.

They are not rare, revision B of the A4000 motherboard was the most common board of all of them.Commodore never sold bare boards though,they were likely left over from production runs that were not finished when they went under..
i would say revision 1 and C(printed as revision2 on the board and stickered revision C) is way less common.

Thanks for the feedback.  I have seen the A4000T bare boards that were reproductions but not a desktop either.

In terms of it being from when Commodore went under, I would have guessed the last rev (Rev D) bare boards may have been left over and they would have used up the previous revs.  

It's definitely interesting and is a great looking board.  Too bad it's more than two layers or it might have been useful for reproduction.  I do have an A4000D with the same Rev B board that can use some fixing :)

You may be right, but commodore had outside companies making a4000's also ,CEI comes to mind. Maybe leftover from them? who knows.

I have fixed many a 4000 boards, so i know where you are coming from. It was known batteries did damage pretty early on,i wonder why so many people ignored them.

Well they are either surplus or faulty. They represent a point in a process cycle so I am assuming there could have been boxes of these lying around at some stage. The rarity is down to two things really. The first being the number that are in circulation and the second being the number of folk that want to acquire the board. Personally I wouldn't do anything with the board other than place it in a sealed container out of the light. And then look after it. If you are unable to do that then I would be more than happy to look after it for you.

Having a mint board just has to be valuable. The trick now is not to damage it. Please don't damage it.

As to value, well that can only enhance as time goes on.

One of the most common items that I get asked for is my unused, still in its original box, Amiga 4000T case [Escom]. No motherboard just the case mint. And I bought that for a couple of quid off Ebay.

Look after the board. And well done. And wow am I jealous.

Yah... never seen a source for bare 4000D either. If i recall correct it was from Vesalia I bought the two A4000T bare boards I have framed in my office... think they where like 9$ a peice back then.

You should take some high resolution photos and submit them to The Big Book Of Amiga Hardware for inclusion in the A4000 page since there are currently no photos of unpopulated boards there.

You know using it as a work of art,

If you stand back far enough from the wall it is hung upon and slightly blur your eyes, it does look like Renoirs' "Luncheon of the Boating Party"

I still have my very first C64 motherboard.  Someday I'll figure some kind of creative way of hanging it on the wall! :)

Scuzzb494,

Thanks for the reply.  I actually have a couple of other boards that are pretty cool but they are not Amiga's.  My most favorite is still my bare MITS Altair Rev 1 CPU board.  

I will take good care of it.

Good suggestion.  Email and pictures sent.

As for the artwork, while it is awesome looking, it is a symbol of what killed Commodore.  I'll frame it but I'd much rather frame a bare Commodore 64 motherboard; a representation of their success.
