Yes, this is the idea I am pursuing now. I know about
acard, but all tha boils down to a simple question of
that SCSI pin connector. The Indy has 50pin (that
how that thread started) and what attracted me on the original
LF-D201 solution was that that drive apparently has 50 pin scsi.
I am unable to findout what connector has that AEC-7720U
of acard but I think it's a safe bet it will be 68 or 80 pin.
The 50 is so old that I doubet anybody makes it.
There exist however, 68/80 to 50 pin convertors, unfortunately
those that I know are all internal cards, not external
boxes which would be a solution. I am not sure how could
one use those internal cards in this case.
Or am I so far from the reality that there is a simple
solution that I simply don't see? I'd appreciate any
insight/advice in this.

Teach me, please: what is LVD & SE ??

I found that reference during my googling, but you get nowhere following
up those links, unfortunately.
Thanks to all for the help, I appreciate it!

AEC.7720U has 50 pin SCSI. Believe me this is not 'so old' that nobody
does remember.
have a look here: <http://www.acard.com/>
or here (as I saw 'CH' in the email address)

I naively thought I'll be able to find a place to buy lf-d201
(because I'm interested in your backup solution for my Indy
it also has 50 pin scsi) but extensive googling found only
a lot of reviews but no place to buy.
eBay doesn't have it either.
Any idea where I could get it?
Try http://www.zsource.com/PRODUCTS/Panasonic/Panasonic_LF-D201/panasonic_lf-d201.html
They pretend to have "special pricing" on it.
Thanks andbest regards,
Impressed, I dit not know that there where any SCSI CD/DVD roms anymore  |
But I think a good IDE-SCSI converter is a better solution in the long
run, should give better options.

Beware. Not every IDE-SCSI bridge will handle CD/DVD drives. Some do, some
don't. Sorry, I don't have access to the lab that has the equipment any
more to tell you which is which.

(being the OP) I must second that. Go and search forums.nekochan.net... |
Btw., the RO problem vanished with another (new) DVD-RAM media :-)
Now for SCSI-IDE adaptors: pretty good a solution for harddrives.
I have tried Acard 7720U in SGI O2 - didnīt work, but an out-of-prod
Yamaha adaptor did. The Acard 7722 is said to be especially suited
for exchangeable media (CD writers and the likes).
I myself did not try one yet.
At the point where there appeared a built-in 1GB barrier in cdrecord
I have quit experimenting with IDE DVD-writers on SCSI-IDE adaptors.
Native (narrow) SCSI DVD-RAM drives AFAIK canīt copy DVD movies - but
that is not what I was intending to do. Iīll leave that to someone else.
Since DVD-RAM backups data with pure IRIX this is my solution of choice.

That depends on which version of cdrecord you're using, AIUI. There's a
'cdrecord-prodvd' package that should handle the larger media. The
author's site for cdrecord is at:
ftp://ftp.berlios.de/pub/cdrecord/ProDVD/
Packages from other sources may have different limitations. |

believe me: I got the very latest version from exactly that source.
It is said to be free for non-commercial use but there are built-in
limitations (license expires from time to time, demo 1GB barrier).
I asked the author about how much a commercial license would be,
but did not even get any answer.
And whatever I tried - the 1 GB limit stayed with me.
Since I have other things to do and canīt dedicate all my free time
to solve the riddles of cryptic/enigmatic/whatever software I gave up.
If I can afford it Iīd like to _pay_ for software that works for me,
and I canīt stand software I can get for free that makes me work for it.

Probably you should try to set a shell variable like me (for bash):
CDR_SECURITY=8:dvd,clone:sparc-sun-solaris2,i386-pc[....]
Works perfect.

Agreed. The site I mentioned is not the easiest to understand, and the
software itself is even more enigmatic. Oh well...it was worth a shot. |
