The HP price list for the Series 700 machines has the following curious disclaimer: Note: All HP Apollo 9000 Series 700 storage products comply with the SCSI II specifications. The SCSI II specification allows for a variety of implementations, and HP uses this variety to achieve the range of price/performance required by our customers. Does any one know what this means and why it was put in the price list? Does it mean that SCSI on the Series 700 is non-standard, and it is going to be difficult, if not impossible, to attach 3rd party SCSI devices? --wayne

If it works, great! If it doesn't, oh well. I'll bet that most SCSI drives from reputable companies would work just fine. BTW, my old roommate, who worked at Maxtor, said he used to hear the firmware guys bitching about having to go through hoops in order to work with every SCSI interface card in the world. >--wayne > | Ken Sumrall | Internet: ken%hpda@hplabs.hp.com | | HP California Language Labs | UUCP: ...!hplabs!hpda!ken | | "I'd stomp desert dope heads for some gas in my moped!" - Bill the Cat | | "What a stupid world" -Calvin (speaking to Hobbes) |

I believe it trys to state what eventually becomes obvious to anyone who deals with implementing SCSI peripherals from multiple vendors.... SCSI and SCSI II are standards, but many vendor's products have features that may "improve" on the standards, etc. What I believe the statement (my own interpretation, not HP's) you quoted is trying to stay, is that, in the real world, since SCSI peripheral vendors are sometimes implementing things slightly different, the S/700 does it's best to interface to these different "dialects" of SCSI This is my interpretation, not necessarily that of HP, the folks that make the S/700, disc products, the commissioner of baseball, etc.
