If it is a geniune 4000T, it will already have SCSI.
The minimum cpu(at least for the Amiga Tech version)
is an 040, but you will limited to 16MB of Fast Ram,
since the motherboard simm slots are the only way of
adding ram to a stock 4000T. I don't believe the
motherboard revisions for the 4000T are an issue. As far
as ZIII video, the Picasso IV is the best way to go
since it has the scan doubler/flicker fixer built in.
