To summarize: The power supply only has current allocated to power *ONE* external drive. This is why the drives don't pass power through to the second drive. Now if you don't have any other power-sucking accessories plugged into your amiga, it can probably power another drive or two. If you do, then you might try it, but understand that you may blow away your power supply. They aren't all that cheap to replace, and your Amiga will spend some time on the bench... As an aside, the original expansion drives do not pass power through. Somewhere along the line, the PC board in the drive was 'improved' to make connection to alternate vendors drives easier. Unfortunatly, someone hooked up the power on the output connector. So, there's some that do, and some that don't. Since it's the same power supply in the Amiga, the old rules still apply. -- George Robbins - now working for, uucp: {ihnp4|seismo|rutgers}!cbmvax!grr but no way officially representing arpa: cbmvax!grr@seismo.css.GOV Commodore, Engineering Department fone: 215-431-9255 (only by moonlite)
