Amiga 2000

Nice!  Looks like a decent system with some upgrades already.  A2000's can be a lot of fun.  +1 to get rid of that battery!  :hammer:

[Oldsmobile_Mike]

If you want a battery on there, you should replace it with something like this:

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!

[Oldsmobile_Mike]

Yes, that should work.  You plug the 4-pin connector on the board directly into the 4-pin connector on the hard drive, the shorter the cable the better.  As an alternative I believe you could power the hard drive directly from the A2000's PSU and plug NOTHING into the connector on the board, this is if you didn't have the special Female-to-Female cable.

[Oldsmobile_Mike]

Remove all the cards and try again.  You should get the "Insert Workbench" disk, at least.  If you're using a 1084 or similar, you sure you have it set correctly?  Try via composite output, perhaps?

[Oldsmobile_Mike]

So it boots and you're able to see the Workbench screen when it's connected via composite cable? Are you sure whatever monitor you're using is working 100%?

[Oldsmobile_Mike]

Off the subject, but i see you keep saying "the shorter the better" on the scsi cable, on scsi1 the cable length is allowed to be 3 meters,so figure over 9feet is acceptable. I have used everything from 1ft to 7foot cables with tons of devices and they all work fine. SCSI 1 is quite forgiving and works well. proper termination is important on any scsi.

I was referring to the 4-pin connector running power from the A2091 card to the drive.  Wouldn't you say "the shorter the better" on that, too?  Not to mention he's not going to want a 9' long cable coiled up inside his A2000, LOL!  :roflmao:

[Oldsmobile_Mike]

I'm still having a really hard time figuring out what this user's problem is, anyway.  It sounds to me like his A2000 works fine, just he's received a dodgy video cable from some ebay seller.  IMHO I would just try the Amiga with one of the known-good cables from one of his other systems to verify it's working correctly.  This discussion on resistors in monitor cables came up in another thread, I've never seen anyone needing those.

Maybe I just need more coffee.  

[Oldsmobile_Mike]

I'm assuming you don't have any other system you can test the hard drive in?  It's possible that the hard drive failed (often happens due to age, being jostled in shipment, etc.).  What ROM version does the A2000 have in it?  Do you have a Workbench install disk with HDToolbox on it?  The Workbench 3.1 Install disk works fabulous for this if the system has a 3.1 ROM.  

[Oldsmobile_Mike]

Great!  Do you have a 3.1 Install disk?  Does the drive not show up at all when you run HDToolbox?

I'm thinking if the drive doesn't show up at all it's possible that it might still be saved.  Check that it's spinning up, and you'll need to check your cables and termination.

Alternatively SCSI drives are pretty cheap still on ebay, you might pick up a small one just to test with.

[Oldsmobile_Mike]

Well, I'm no expert in Amiga SCSI by a long shot, but I'd start with checking termination.  I recall you said there as an accelerator in there but it had been removed, so things might be a little screwy.  I'd check that your ribbon cable is hooked up something like this:

A2091 ---> Hard drive ---> CD drive.

Obviously check that pin 1 on the cable goes to pin 1 on the devices, then check the jumpers on those two devices.  There should be one for termination on the hard drive and it should be off.  There should be one on the CD drive and it should be on.  In other words, you'll want to terminate the last device on the chain.  So if your cable is going the other way around (i.e., connected to the CD drive first and then the hard drive) you'd terminate on the HD.

It gets a lot more complicated than that if you need to throw in active or passive terminators, etc., wait for someone with more knowledge to chime in if you need that kind of stuff.

[Oldsmobile_Mike]

Wait, you said the hard drive is not spinning up?  You have the power connector plugged in the right way?  Try powering it directly off the A2000 PSU?

[Oldsmobile_Mike]

If you pull off the LED housing you can see which wires are connected to which LED. Just squeeze it a little and tug. Wait, that sounds naughty. :p

AFAIK you won't hurt anything by hooking them up backwards, but these not being connected won't stop your hard drive from being identified by HDToolbox. When you start HDToolbox, does it say anything like "scanning scsi.device"? Are the tooltypes for HDToolbox set for the right device?

[Oldsmobile_Mike]

Hi it said nothing about scanning ,and I am not really sure what Are the tooltypes for HDToolbox set for the right device?[/ or how to check, all I can say is the installer is 3.1 which I use on my A1200

If you right-click and get Icons -> Information for HDToolbox, what does it say?  I don't have a 3.1 system handy right now, but I do have some 3.1 install disks.  See attached picture:

[Oldsmobile_Mike]

Well, that sounds like the right settings in HDToolbox, then. I hate to say it, but have you triple-checked the termination on your SCSI device chain? Try unplugging everything but the hard drive and putting the termination jumper on that drive.

Edit: Check the jumpers on your A2091, as well. What are they set to? And what's the ROM version?
 
 Jumpers should match this card, assuming you have the same amount of memory:  http://amiga.resource.cx/photos/photo2.pl?id=a2091&pg=1&res=hi&lang=en
