Amiga 3000T need help troubleshooting

Looks like your accelerator is not making good contact or your motherboard settings are wrong.

Here are the 3000T jumper settings

060
100 3-4
102 1-2
104 1-2
103 2-3

040
100 3-4
102 2-3
104 2-3
103 1-2

030
100 1-2
102 2-3
104 1-2
103 2-3

I would start by removing all boards .... set the motherboard jumpers to 030 and try booting off the onboard 030 then start adding the addons one by one.

Will it boot off of a floppy disk? Could be scsi termination problem. Try removing the scsi cable from motherboard and see if the insert disk screen will come up.

My 3000t did something similar years ago but I can't remember what fixed it. I will keep thinking about it and see if anything else pops into myhead.

Try checking floppy drive cable. I had mine fall off once and just reached up in there and put it on backwards and it wouldn't boot off the HD until I re attached it in the proper orientation.
