<p class="MsoNormal"><span style="mso-fareast-language:EN-US">Luckily for Alberto, there’s basically no such thing as a passive HD68 or VHCI terminator, so anything he finds that’s physically compatible will also be electrically compatible with Ultra160 signalling.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="mso-fareast-language:EN-US">Terminators of all flavours are – amazingly – still easy to get on both Amazon and eBay, and at not-insane prices, too.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="mso-fareast-language:EN-US">Oh, and LSI did make the LSi20320IE chip, which is a PCIe Ultra320 HBA controller – I see one on Amazon for only $115?!? The overwhelming majority of Ultra320 and Ultra160 adapters were PCI-X, which
means server-class motherboards only; you *<b>usually</b>* have to go down to Ultra-Fast Wide (80MB/sec) before plain PCI could keep up. (PCI was limited to 133MB/sec, you can do the math!) 66MHz PCI (266MB/sec) really only existed in PCI-X anyway, so there
you go…<o:p></o:p></span></p>

<p class="MsoNormal"><span style="mso-fareast-language:EN-US">A word of warning, if you’re buying a SCSI HBA (card), make sure you do NOT get a RAID card – those are often useless for tape drives.<o:p></o:p></span></p>
