Is it possible to connect two Amigas via SCSI interfaces with a simple cable? That would be a _LOT_ faster than a null modem! Does it have to be some sort of clever device in between? I would suppose so :-( Just my $0.02 worth!

That would be a _LOT_ faster than a null modem! Actually, I believe I've heard that the Trumpcard Pro has this capability built-in. It is also supposed to be part of the SCSI standard (device ID 7 is reserved for this), though I don't know that it's implemented on all controllers. Anybody with different controllers that knows about this want to speak out? I've got a GVP and the new software and ROM upgrade doesn't mention it. >Does it have to be some sort of clever device in between? >I would suppose so :-( Actually, I think all you would need is a cable. >Just my $0.02 worth! -- =----------------------------------------------------------------= | /\/ Logan Shaw "Come to Me, all who are weary and -+- \/\ lshaw@ccwf.cc.utexas.edu heavy-laden, and I will give you rest." | =----------------------------------------------------------------= |

This cannot be done via the C= scsidirect interface so you would need to talk directly to the SCSI controller chip (which ever one your host adapter uses). This is quite possible, yet I have never seen it done on any system (Amigas, Unix, PCs, minis). Go to it!!! P.S. When you get it done by all means send me a copy, I'd love to be able to transfer stuff that way. Gary /*=========================================================================== | Gary A.

I think that C-Ltd had a product which allowed you to connect up two Amigas across the scsi port and share the devices between the two. Shawn Switenky 874226@watt.usask/ca

I have been searching for something like this for a long time, or at least how to build one. HOW MUCH does this little cable run. Would it work fine transferring data between 2 3000's with fast quantum 210M drives? Thanks for the info!!! -Layton lcc727@unhd

They did have such a product. It had some problems, tho, operating with
the AmigaDOS in-RAM maps of modified blocks. This made it unsafe to allow
two Amigas to write to the same partition of the same disk. "SCSI-Net", I
think it was called. I bought a C-Ltd controller, in hopes of using SCSI-Net
someday.
Several months ago, I talked to a fellow at the firm that now handles
Kronos controllers (Micro-Dyn, Inc., of Witchita, Kanasas). When I asked
him if I could use SCSI-Net to connect a Kronos controller and an older,
non-DMA controller, he said yes; but he warned me that there were so many
restrictions to its use that I would probably not like it. He claimed there
was only one place he knew of where SCSI-Net was in use, and that was by
the folks who developed it (apparently, not at Micro-Dyn). He seemed to
prefer to not sell me a Kronos controller, rather than selling it to me
under the assumption that I would use it with SCSI-Net.
