The 4000 should boot to the insert workbench disk if the hard drive doesn't work correctly.

as to the Cybervision64, doesn't it needs a vga type monitor?

Often the reason for a black screen is the cpu card is nor inserted incorrectly, reset it.

I have a dell monitor that syncs to both 15 and 31
Oh well...
Do you have a local amiga users group for help with parts and testing?

Here in Sacramento, when we need help, we just ask each to swap parts or test.

If you are local (don't know as your profile is blank) to us, give a call

My Dell SR2320LF and ST2420LF both work at 15 and 31

Doesn't a red screen indicate a memory or rom problem?
Maybe Pull the memory, clean the contacts and the same with roms.

Just be careful not to break the holders on the memory slots! (from sad experience)

I still think the cpu board also needs to be pulled and contacts cleaned then correctly installed...

On the 3000 drive, older scsi drives from years ago had a stickion issue.
Where if the drive wasn't used it "stuck" in place. I saw one guy rap the drive as it powered up to free it but...he had to replace the drive anyway.

Is there any battery leakage on the 4000, it could have eaten at the memory simms?

I don't know WinUAE. And I have never tried setting up a drive in a pc.
I prefer to just use amiga.

But I have Amiga Forever, it uses WinUAE but with custom setting for various Amigas. Great package! Recommeded!

So many questions...Does the 4000 have a battery? It's just by the simm sockets on the motherboard, big cylinder thingy!

Can you attach a pic?

If you are the first owner and never removed it...GET IT OUT NOW.
If it didn't leak before, when you started powering it up again, it will leak!

On 3000D hard drive.
It should be attached to a plate, which is supposed to be held in place by on screw on the inside corner.
Further then, the tray has flanges that slid in place and yes, there is the data and power cables which restrict movement.

The easy way to remove. Remove the screw. Slide the tray forward a little, pull the cables and let them just hang. Pull the tray forward the rest of the way and you should be holding a hard drive with tray attached. Turn it over, remove the four screws and reverse the process to install a new drive.

BTW, the 3000D also has a battery, under the zorro boards...pull it out!!

On the 4000 battery, even though the picture is not the cleanest...

I can clearly see battery salt.... it has started leaking!!!

This is not the right way...but At the very least, just rock the battery back and forth.
the three solder points should break and the battery is out!

BTW, Blow out the cat hair!

We see so many dead and un-repairable 3000 and 4000 motherboards due to those damm batteries!!!

Found my original Workbench 2.1 disks. First try got a read error but on a second try success

That changes the goal for today to finding a SCSI drive. I think I might have one somewhere.

Does anyone know what is holding the drive in place? It seems to not be anchored to either wall but rather something flexible is holding it from the bottom front. There is no way to see under and I have never seen a drive held in place this way. Don't want to rip it out if there is a proper way to remove it.
on the floppy errors..

It's very likely the fuzz and hair. Blow out the mess.

Wait, the hard drive and floppy drives are mounted on their own mini trays that slide into slots/holes on the large tray covering the motherboard.

Yes, the battery is really only for the keeping the clock time.

Yes, the 3000 also has a battery, under the zorro cards, just pull the card out.
Makes it easier to clean.

The only way I can think of to see if the 2065 card is "good" is just hold down the two mouse buttons on power up and check on the cards, if it says working, it's okay (I think)

If you have a au to rj-45 converter... you can hook it up to a router (if you have one)

BTW, the card check will confirm the gvp PhonePak "working" card as well.
