Any words of wisdom on hooking up SCSI drives on a Personal Iris? Those 1/2 height 5-1/4" drives are just too darned expensive. I'm looking at 760 meg in a shoebox for about $2K. Where in the PI should I try to hook in the external SCSI cable. The only point-of-attack I see without taking the PI apart is the extra 50 pin connecter in the back of the empty 1/2 height slot above the tape drive. I could get some 50pin ribbon cable and route it out of the PI here, unless there is a better point to connect. More importantly, will IRIX be able to format and recognize any 3rd party drives? I would think so, but I'm looking to be sure before I jump in. -- Vincent Fox (That's Mr. Bucko to you)|Georgia Tech, the only place where Friday Georgia Tech, Atlanta GA |is only two working days away from Monday.

No; you want to use the external SCSI connector, in the back next to the I/O panel; that is what it is there for. It is the standard SCSI pinout for that that connector (as spec'ed in the SCSI 1 standard). Note that the pinout is NOT the same as the numbers molded into the connector! You should be able to get the correct cable at most large mail order or computer supply operations. The connector in the top slot doesn't match any standard, and isn't likely to match any cable you can find, except by pure happenstance. | More importantly, will IRIX be able to format and recognize any 3rd party | drives?

Well, not ANY 3rd party drive, but it should work with just about any drive that conforms to the CCS addition to SCSI 1, or with any SCSI 2 compliant drive, assuming you are using IRIX 3.3 or later. Use the fx program to initialize and partition the drive.
