Amiga 2000

[mechy]

When I replaced my battery I soldered a CD audio cable with 1 end cut off and put the battery on a small board with connector pins on it, then mounted it behind the LED's, no ISA slot used so fits great and I can remove it easy for replacement, no removing the motherboard!

why not use a cr2032 socket with a diode and lithium battery, they don't leak and you can replace it easily. I hate to see it,but people still insist on installing nicads,nimh and or alkalines,and even off the board these can do damage because they can outgas when they leak and still corrode components. I say remove the threat entirely.

Couldn't agree more.

Thanks for the closeup of the battery, but if you look at the area where the "green" covering meets the metal, you will see a white powder; now either your battery is snorting cocaine, or you see the white salt of corrosion.

My vote is for the latter.  Please note that that battery is a 3.6V and the coin cells are 3V; added to that the diode removes about 0.3 to 0.4 volts and if you want your clock keeping time, you should get a new 3.6V (unlikely to leak) battery (from AmigaKit).  Removing it is simple if you don't plan to replace it, just clip the three legs.

Hi I have a few cables that I am not sure where they go ,can any one tell me where the two loose cables should go ,I know there was a accelerator but that was removed ,and I notice there is no power cable connected to the hard drive ,as any one any idea please , these are the sellers instructions
  you will have to fit the SCSI cable back on to the commodore scsi card and the led for the scsi card, everything's there ready but I unplugged it all as it was originally on the accelerator card, I simply put the scsi hard drive back on its original place.

Uh, do you see the 50-pin "header" right next to the hard drive?  The one labeled CN6 with a "1" at the bottom; this is the SCSI controller connector.  There should be a power connector for the hard drive as well that says, "power."  A short 2 to 3 inch cable used to connect the CN6 to the SCSI connector on the hard drive and a short power connector with two female ends connected the one below the CN6 to the hard drives power.

Does this seem plausible?

[danbeaver]

OH, nice flowery table cloth, by the way.

You're killing me, man. Since I happen to have an A2091 sitting right next to me on my shelf, I made the attached picture for you. Plug the 50-pin ribbon cable into the 50-pin header on the board, and the 3-pin power LED cable into the 3-pin power header on the board. As @danbeaver said the 50-pin cable should only go one way, you'll want to match pin 1 to pin 1 on the cable (usually red). The LED cable can go either way. If for some reason it doesn't work, try flipping it around.

The power cable is the four-pin molex connector. It can only plug in one way and should be obvious.

I hope this helps, my hope and prayer is that maybe someday everyone will start using the built-in forum tools to attach pictures, instead of linking to external sites. Sorry, pet peeve of mine.

Hopefully there's no accelerator-specific software on that hard drive that will prevent it from booting with the accelerator removed. You'll probably want to format it and do a fresh OS install, anyway. Good luck!

[danbeaver]

OMG!  Is he (are you) feeding power INTO the A2091 card?  Don't do that, it takes power from the bus to supply the hard drive.

Hi thanks I cant get a power connector on to the hard drive because there's not enough room ,is it just the six screws that hold the hard drive in place as I need to remove it to gain access to it ?

[danbeaver]

Yep, you have to loosen the hard drive from the board to attach the power cable (and you may have to trim the plastic Molex connector to fit); kinda the same for the SCSI connector, but the card is self contained: power comes from the card (via the Zorro bus) to the HDD, and the SCSI connects directly the the HDD's.  

Longer cables are used to add other other devices to the card, while the external 25-pin D-Connector adds external SCSI devices.

Hi I have installed the 50 pin ribbon cable and the led ,does that look ok

[danbeaver]

Well, yes, pretty much; but I don't see the power supply to the hard drive.

[mrmoonlight]

lol , yes I am going to move the hard drive so I can connect the power cable
and can I ask again about the power socket just below the 50 pin header do I need to put a power supply in that as well ,

[danbeaver]

:laughing:Interesting Card from your PhotoBucket site; have only a few relatives?

NO!  It is there to supply power TO the Hard Drive.

Hi I have a three inch cable female is that the one that goes between the two
