My new Amiga 4000T - work in progress

You only need the disk module to boot.
Connect the SCSI cable to the terminator on the I/O module to stop scanning for SCSI drives and thus faster boot.
The J100, J104 jumpers are set to EXT?

Most likely the missing A3640 caps is the problem.

You don't need an IC puller for the Kickstarts, a flat-head screwdriver works fine.

Do you have spare oscillators (50 MHz, 28.375160 MHz) to try out?

You get the same effect if some of the customs chips on the motherboard are not functional.
