As I had texactly this drive inside my TT030, I can confirm it does 
require the computer to have an SCSI ID. It did not boot in the TT030 
with original ROM, one has to use a patched ROM, I used tp306v20.lzh and 
tospatch.ttp, both which can be found on

<http://markusheiden.de/index.php/atari/tospatch.html>

These were the two modifications necessary:
