Some success. Managed to get A4091 ROM to initialize NCR chip and it also started executing SCRIPTS code correctly (at least it looks correct, debug logging looks ok, correct looking SCRIPTS opcodes are fetched from memory etc..) and it attempted to select first SCSI device.

Next step: add missing SCSI glue code and connect NCR emulation to UAE SCSI devices and check if selection actually works..

(Yes, not very useful feature but unpatched A4000T KS ROM will hang without SCSI hardware)

EDIT: Works if no SCSI devices connected, select timouts work. Which is better than nothing, it allows original unmodified A4000T ROM to boot properly for the first time.
