You're looking for the pre-SCSI form of disk interconnection, the so-called "SA-1000" interface. This was the connection interface for the larger 8" rigid disk drives that wre used in the 1108. Thus it's possible to add almost anyone's disk that matches this somewhat dated interface format. There are a number of "hopped-up" 1108 and 1186's within Xerox that are running a 150 MB disk, though I don't believe that it's a Quantum. Jesse's right, Quantum's still very much in the disk drive business, having one of the very popular 5" format 105 MB SCSI drives that's in a lot of units these days. If you change out the disk drive to a higher capacity, you'll have to do some messing with the Othello layer and also make certain that it'll play with whatever you're running. Viewpoint, for instance, needs a different software disk driver. If you're sticking in the Interlisp world, I suspect that simply altering the track formatting parameters through Othello would be sufficient. Even though I'm an employee of Xerox, these comments are simply my own and relate to my own days of being a grad student suffering with 1108's. -- | | Norm Crowfoot Voice: 716/422-2458 |\ | KBS Competency Center Internet: crowfoot@arisia.xerox.com | \ | Xerox Corp - MS: 0845-20C XNS: ncc:wbst845e:xerox | \| 780 Salt Road FAX: 716/422-2479 | | Webster, New York 14580 /|\ / | \
