OK I need some help on this.. I'm currently using a computer with 2 IDE harddrives and a AT-Bus CD-rom.. Now can I also get a SCSI conntroller and daisy chain the hardrives as e:+ etc.. And also get another CD-Rom Scsi? Or do I hafta chuck out the ide's and my curent CD-rom? I would like my system to be Scsi based but want some suggestions.. Also I've been looking around and think that I would like to purchase the AMI Scsi Caching Controller.. It's 32-Bit EISA and Adaptech 1542 A & B and BusTek compatible.. it also has a 1/4/16 Meg chache Memory and ofcourse the FDD controller built in.. So what do you think? Should I go for it? in case yer wonderin I'm using a 486-50DX with 20 megs ram and runnin under os/2 but keep switching back to dos & windows..

Yes, many SCSI controllers can co-exist with IDE hard drivers. That is what I have currently in my setup currently. If you want to get some good information on the different SCSI controllers available try the IBM hardware forum. Several reps from UltraStor, Procomm and others hang out there and give you more detailed information. (GO IBMHW). Also if you get a SCSI controller maker sure it has ASPI drivers. This helps in supporting many of the different types of devices out there.

I have two IDE hard drives, and an old CD ROM drive which I will replace eventually – I have no idea what the interface is to the CD but for discussion purposes lets assume that it is not SCSI. I have an SBPro so could use that proprietary interface to add the CD. Eventually I would like to also add a tape backup, perhaps some more disk storage. What are the advantages for me to move to a SCSI rather than staying with the IDE's and whatever comes with the PC specific peripherals. – Dan

Dan, SCSI advantage is one host adapter handles 7 devices directly. It works with many different types of devices. Scanners, WORM drives, MO drives, CD-ROM drives, hard disks, ethernet cards, etc. Also with SCSI devices they are hardware/platform independent. So if you move to a MAC, Atari ST, SUN (unix Workstation) you can use the same devices provided they have a driver. For example I have used my external CD-ROM drive on a SUN, RS-6000, MAC, Atari ST, IBM PC. Since its a SCSI device its easy to move around to different systems when the needs arise. Even when they are temporary. Also some Operating Systems (OS/2) for example only supports SCSI devices. Performance all around is very good to excellent with SCSI devices. With a PC you can buy CORELscsi for $99 and it works with many of the devices listed above. (GO COREL) and download the file MASTER.TXT and it lists all compatible devices. Also many SCSI host adapters can easily co-exist with an IDE adapter and other SCSI host adapters (usually the same make works). So you are not limited very much at all. I look at SCSI not as an expense but a LONG TERM investment. With the introduction by ASPI by Adaptec this has made a SCSI a great solution for having many devices on one PC. Make sure you get a SCSI card with ASPI since it solves many of the problems faced when configuring a new SCSI system on the PC. Also ask a million questions and then a million more. Its always better to have too much information before purchasing anything than too little. SCSI = great performance and a great investment for the future!
