What kind of cable do I need to connect my heidelberg linotipe saphir 2 with Mac G3 which had Ultra 3 SCSI LVD/SE connection? Do I need terminator passive or active and where the terminator will need to be connected?

The SLR60 is a SCSI device. First you need to acquire a SCSI adapter, such as an Adaptec 29160 or 39160 PCI SCSI adapter. Both the adapter and the SLR60 have 68-pin connections, so you will need a cable similar to this one: http://www.cablestogo.com/product/07858/3ft-scsi-3-ultra2-lvd-se-md68-m-m-cable-thumbscrew. Once you have all of this, connect the tape device via cable to the adapter. You will need a 3rd-party backup program, such as Seagate Backup Exec or NovaBackup.
You may never acheive the full bus speed as most manufacturers have a habit of giving their specs a little tweak and most mainboards may have conservative bus speeds too.
You also have electrical losses in cables, low bus speeds and slower read/write speeds.
Most people have at least 2.5 gig internet access speed but they will never reach that speed, most can only get as high as 50 or 60 meg due to cable losses and other restrictions.
you may also have component issues which may be slowing things down too.. but to be honest, if you can get to about half what the specs tell you, you have done well..
Yes. Just got mine running on Windows ME. Problem is getting the SCSI set up. Once you get that done, I used Vuescan (http://www.hamrick.com/) and it works. Slow, but functional. I have yet to get scans of the full scanner screen (10 x 14 inches). But 8 x 10 is working fine.
Usually, SCSI devices come with the termination built into the device. Older devices actually had two or three terminating resistor packs plugged into the card or drive circuit board. More modern ones have DIP switches to turn the termination on or off.
Essentially, on a SCSI daisy chain ribbon cable with multiple connectors, only the first and last physical device needs to be terminated. Usually SCSI devices come from the factory already terminated. If you have only one device to connect check and see if there is a DIP switch to change. I would go ahead and connect it. If it works, it's probably already set properly.
That said, I have worked with daisy chains of SCSI devices where a particular device would only work if it were terminated even if it was in the middle of the chain. s
As I recall, this is a SCSI device. Like many electrical connectors, SCSI connectors can develop a light corrosion which can keep the signals from being transmitted. The easiest way to clean such light corrosion is to shut down the Mac & power down *all* SCSI devices in the chain. Then gently unplug & replug all SCSI connectors. This will scrape off much of the corrosion & usually results in connectivity being restored. Be sure to unplug and replug the SCSI terminator attached to the last device in the SCSI chain. Restart by powering up the SCSI devices and finally restarting the Mac. Good luck!
I've now managed to solve this initial problem by installing the relevant extension for the SCSI PCI card, however when I try to launch the scanner software the error message 'No communication with scanner" pops up
I've tried the obvious cables check etc. Any ideas?
