Amiga 2000

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.

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.

[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.

[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.

[danbeaver]

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

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

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 ,

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

[danbeaver]

Three inches sounds right -- it is female-to-female; to the best of my knowledge, that is the only card with such an odd power (cable) arrangement.

[danbeaver]

If it is not spinning up at all with real power applied, then it is probably dead; some would say to bang it against something hard to see if that works, but regardless, it is dead or near dead.

[danbeaver]

Uh, yes, the Buddha IDE device will hook up a CF card or IDE hard drive for your A2000; your A2091 will work as well, but requires a bit more expertise.  As an aside, not all CF cards report themselves to the IDE controller as "hard drives," and the TrueIDE device corrects this flaw making most all compatible.

As suggested above, a good search on the internet can retrieve more information than using a Zork-based adventure game of text questions and answers in a hardware forum.

Best I can tell:
Rev 5.92 ROM's
HDD: Quantum - SE21S011 - 2.1GB SCSI 50PIN 5400RPM
SCSI: WDC V-08 (?)

An IDE interface decreases the skill set required to get a storage drive (CF or HDD) working on an Amiga, but it is in no way the "Magic Bullet."  I would suggest that once you have a working A2000, go back and revisit the SCSI issue; retro computers are also a way of learning something new from something old (and please, in that line, the space comes after the comma -- some of us have OCD).
