We need some technical info, to install a 380Mbyte Hitachi SCSI disk on our 3B2-400. Unfortunately we dont have a productspecification, and we're unable to obtain it from our vendor. The SCSI-disk is a: HITACHI DK514C . We need the parameters for the two commands: Format Unit Command (04H) Mode Sense Command (1AH) If anyone has this info (or know where we could obtain it), please reply to: ...uunet!mcvax!dkuug!netpasser (or netpasser@dkuug.dk)

I am writing a paper on SCSI and it's future. I was wondering if anyone had any data for sales of SCSI related products. Forecasts would also be nice. Also, any comments about SCSI-2, SCSI controllers, etc. would be most helpful. Thanks. =============================================================================== David T.

From what I can tell, SCSI falls under the catagory of "the nice thing about standards is that you have so many to choose from". The theory is supposed to be that if it's a SCSI peripheral, you can plug it into a SCSI system and it should work, modulo some driver software. Well that's nice, except that Sun does something funny with the ground pins. And Apple uses a non-standard 25-pin connector instead of the 50-pin amphenol. With Apple, you're supposed to use a 25-to-50 pin "system cable" to get to the first device. Except, now I see Mac peripherals (notably CMS disks) with 25 pin connectors on them, so you need a 25-to-25 cable to the first disk and then your 25-to-50 cable to the rest of the SCSI chain. But wait, what about this neat HP scanner SCSI interface box; it's only got a single SCSI connector, so it's got to be the last thing on the chain with a feed through terminator, unless you've got stacking SCSI cables. And some disks have internal terminators which you have to remove, or make sure they are at the end of the chain. SCSI's a great idea, but with everybody taking pot-shots at the standard, it's quickly turning into a mess, just like RS-232-C. -- Roy Smith, Public Health Research Institute 455 First Avenue, New York, NY 10016 {att,philabs,cmcl2,rutgers,hombre}!phri!roy -or- roy@alanine.phri.nyu.edu "The connector is the network"

Joe compiles an annual SCSI Market Study and generally keeps a pulse on the mass storage industry. Alas, it comes at a price. Be prepared to pay several hundred dollars for the complete package. Excerpts of the Study from the SCSI Forum are probably less expensive. Technology Forums PO Box 1729 Minnetonka, MN 55345 612-934-1415
