Looking for Sony V7021 IC data sheet and Amiga UNIX question

Hi,

Does anyone have a data sheet for the Sony V7021 IC? This is a video decoder
that can be used to convert composite video or S-video into RGB. I can't find
mention of it on Sony's web site at all.

I need the info because I want to convert an old Vidi-RGB unit from PAL to
NTSC. The Vidi RGB is a video colour splitter, primarily intended for use with
old Amiga or ST monochrome video digitisers to allow colour still pictures to
be grabbed. It also provides a feature connector on which are the RGB signals
from the V7021 IC that it uses. I have a PAL model, but want to convert it for
NTSC use. Changing the crystal will be necessary, but I guess other components
may need to be altered too.

Alternatively, does anyone have an NTSC Vidi-RGB that they want to sell?



Next subject is Amiga UNIX (the commercial UNIX product sold by Commodore circa
1990-1991, not NetBSD etc.)

A couple of years ago, I bought a copy of Amiga UNIX 2.03. This was developed
before CD-ROMs were very popular, and so the main OS came on a 150MB QIC tape.
A couple of weeks ago I finally got a suitable tape drive, and I've backed up
all files from the tape onto an MO disk for safe-keeping; it amounted to about
70MB compressed.

Out of the box, Amiga UNIX requires a Commodore hard disk controller. I have a
GVP HD controller instead. I read ages ago that someone has created patches
for the OS to run on GVP controllers. What I'd like to know is:
- Are there any web pages about Amiga UNIX?
- How many versions of this OS were there? Is mine the most recent?
- Is it possible to get Amiga UNIX to install by making alternative install
  floppies which contain driver code for GVP controllers?

If anyone has info about this, or just has a different version, please contact
me. (Is there a mailing list for discussion of Amiga UNIX?)
