Gridrunner,

thanks about battery info.. it has already started to leak!.

Ok, about changing it... 

do I need to keep power to the system, to prevent loosing any information?
( like Cmos batteries on PC motherboards?)

Please let me know asap!

Simon

if you haven't already done it, make sure you replace the battery on the amiga 3000 motherboard. I had two units and the battery leaked badly on one of them writing off the board. Currently I've got one unit and one full set of parts from the sit down version of the game. The big challenge I see is in the tons of wiring that relate to the head tracking, which us neatly encapsulated and aligned in your simulator :)
I'll image the drives I have as they may have driving software on there. I'm missing key disks, so any help there would be appreciated!
 

Key discs ?

let me know more, and i`ll see if i can help.

May I suggest you attach a couple of wires and extend the battery location to somewhere less corrosive for years to come :)

hi guys,
I just did the same repair on my Amiga 500 plus last weekend.
I used a like for like varta part but you might want to use a coin battery. If electrolyte has reached the board wash the area in a dilute white vinegar solution and a toothbrush, then rinse. Check for any trace damage. I just snap the old battery off and solder the new one to the previous solder points, but fly leads and a battery pack mounted in the case would make easier. The replacement needs to be rechargeable. Don't worry about losing data. It's just a battery backup for the real time clock. Left in place these things are lethal to amigas!

Apologies Simon!
 
In the move i've inadvertently seemed to have lost your initial post. I am trying to sort it out but in the mean time you might want to re-post.
 
Apologies.

Simon,

If you need any help with the Amiga 3000 part of that beast, then Retro Computer Museum (link) are based near to you and do have people who can help.

Hi,

I cant find an exact battery online, so I will go for that one I found at Maplins ( see above post )

what ratio of water to vinegar should I use?

SimonH, thanks for that link, I`ll contact them incase I need to replace my board.

It would be really appreciated when you do the battery swap to photo document it and create a new tech thread on here.

You can run the Amiga 3000 without a battery - the only thing that gets stored that is important is the SCSI parameters and they just go to default which usually works.

SimonH,

thanks for that, although I have just ordered a battery from Maplins, that I will be getting tomorrow.

I will test it without the battery though :)

Man this is cool.  I remember being fascinated by these when I was a kid.  Does it bring on motion sickness?

There was one of sale near me in Bolton not so long back, but looked fairly knackered.  Anyone buy that?

Don't worry I wouldn't have bought it, but glad it went to someone like yourself, who is obviously keen on getting it up and running again
