FS: Brand New (NOS) QuickPak Amiga 4000 Towers

[tone007]

I think the QuickPaks were supposed to be some of the few that used Lithium coin-cells, luckily for Red and everyone else.  Otherwise there'd probably a couple dozen pretty cases with wrecked boards inside.

Definitely worth popping a few open to be sure, though.

Nope, they don't. A4000Ts had coin type batteries. They are very probably dead, but not leaking

Interesting, however you cannot rely 100% on information on BBoAH.

Look at the photograph. It is without a doubt an after production replacement. You can see the solder marks on the PCB laquer and you can see the board was designed to take a barrel battery.

The only Amiga motherboard designed to take a Coin type battery was the A4000D-CR

Look how it is a really designed to take a coin battery, the silk screen, the space, the connectors.

I am not saying that all A4000T's did not come with hacked coin batteries out of the factory. It's just they were not designed to have them.

my contacts are playing a little bit of hardball

do your contacts read AO posts?

The Amiga Hardware Database also shows the A4000T mainboard with a coin type battery:

It could indeed be that originally the A4000T was designed with a barrel battery in mind, but I never heard of one actually having one (at least, not from the people that I know who own(ed) an A4000T).

Also, the silkscreened battery outline on the A4000T board doesn't look like a true barrel one either. On the A2000/3000/4000D mainboard it's rectangular. The one on the A4000T is square:

Agreed, but in this case they are right. All my A4000T's (I have 3) have exactly the same, original coin battery:
PIC

Just like the A4000CR (I also own one) the A4000T not only has a coin battery but also an external battery connector.

Makes you wonder, why not fit a coin battery holder instead of a "soldered to the board type one" and an external connector...

Tssss, showoff...

Cool.

Ah, that might explain the picture on BBoAH, A4000T's might have coin batteries out of the factory but in order to replace them you've got to desolder it.

I still think it was a post-design change.

The A4000D-CR (which is wot I got!) was perhaps designed after the A4000T? It has a standard coin battery holder for easy battery replacement.

Anyhow scare over.

While I cannot say with absolute certainty, I do know that even my Commodore A4000T (not ESCOM), serial #14, had a coin battery.  Every A4000T I have seen has had coin batteries... soldered to the motherboard.

RED, AFAIK A4000T motherboards used LiH alkaline barrel batteries that were prone to leaking, just like A500+, A3000 & A4000D. If they have never been touched since they were manufactured in the late 90's I'd bet money that most have leaked. I would find out what condition they are in before buying.

[dannyp1]

Every A4000T I have seen (maybe 10 total) had a coin type battery that was soldered in place.  They were not in a holder where they could be easily changed.  I have never seen an A4000T with a barrel battery.

Perhaps some of the  Pre-production A4KT boards had barrel type batteries. Otherwise & afaik, 4000T's were Always a Coin Battery. I've owned several myself & have seen loads of others too, but all with Coin Battery.

RE the A4KD Rev D with on board CPU & Coin Battery, these machines were a vain effort to reduce costs & the battery in there was a cheaper solution than the barrel kind because of the surface mount process making the whole production cheaper.
I guess the A4KD rev D just rolled on with progress, as it did with the Coin Battery from the A4KT.  ;-)

My A4000D-CR certainly doesn't have the coin battery holder, it's soldered directly to the maininboard like the A4000T

Maybe I can shed a little light on this. I bought some A4000T's from SH last year, and they had to go through these Secret Squirrel negotations - apparently with the same source. If so, they are solid units with NO leaking batteries. I just took one apart for this post, and the motherboard says:

A4000T Rev. 4

and it has a working coin lihium battery. The sticker on the back of the case says:

Made in the USA
Amiga Technologies GmbH
FCC ID MK9A4000T
SN# 365317-19-00726

The 060 accelerator card, as HammerD noted, is the second smaller "desktop" version of the same board, named A4000-060 XP Rev. 2. I suspect these are the type still available.

These are primo machines, and I'd advise anyone interested to get one from redrumola while they can!

[TCMSLP]

Any news on these?  If people are planning to ship a few to the UK, I'd like to add my name to that list!

Thanks,

Sounds like a plan, locked.
