Well shoot, I thought I was onto something there, oh well, thanks for checking on that for me. I'll try to pull it out again tonight and have a look at the overlay line.

$35 is not as much as I had assumed it would be, international shipping has gotten hugely more expensive in recent years, sending stuff to the UK costs at least 4x what it did 10 years ago. Still $35 over, assume roughly the same to get it back and that's $70 in postage alone and doesn't count paying you for the work. It's not that I can't afford it, but I've got a mountain of projects competing for my money and time. Also I'd really like to figure this out, sending it out feels a lot like giving up.

Ok that gives me some ideas on where to look, I haven't had a chance to get it out again but I'll report back with the results when I do. So this is with the original kickstart ROMs fitted rather than the diag ROMs?

Well the battery is gone because it leaked on the board and made a mess which I believe I've cleaned up. Hard to say if there's more damage lurking when I can't get it to do much at all. I never get anything on the screen, only thing that happens is the power LED goes from dim to brighter, IIRC with the Kickstart ROMS there is a brief burst of activity on the bus immediately after reset and then it halts. Still haven't had a chance to mess with it more but will do further tests soon.

Would definitely try terminating the scsi. My 3000t had similar symptoms until I put a terminator on the end of the scsi chain.


I did have a terminator on there initially when I was messing with it, haven't tried terminating with the diag ROM. I'll reinstall it for further testing.
