Memory card locations are special, meaning they aren't EMCA slots.

I can't answer 1), but I can answer 2) and 3). The SCSI adapter does sit on the MCA bus. It has a connector on the back end of the adapter, which is available to connect anything you want [ more or less ]. To connect a new SCSI device, power off the machine [ duh ], cable up the new device [ making sure you don't duplicate any SCSI addresses ], and re-boot. The machine should locate the new SCSI device when it configures itself. There is a "Hardware Quick Reference Guide" which gives LED values [ numbered 800 and up ] for the different devices. Look up your device in the back of the reference guide and you should see your device ID flashed on the LEDs while it is being configured.

No the members of the RISC System/6000 family all have separate slots for memory cards and for MicroChannel adapters. The two types of slots are not interchangeable. The POWERstation 320 has 4 MicroChannel I/O slots and two slots for memory cards. I'm at home and don't recall the answers to your other questions, sorry.

Hello. (1) Yes (2) Yes (3) Yes, but there's some debate on the total number of SCSI devices that may be supported (as distinguished from actually work) on that adapter. As I recall, the Official Announcement states that only a total of four SCSI devices are supported on the controller in this situation. On the other hand, I have heard that up to seven will in fact work. My secretary, if I had one, would deny I said that. Given my waffling answer to item (3) I strongly suggest that you contact your local branch office (or me, when I'm at my desk) to find out the exact details on any configuration. There is a fine (and frequently important) line between what will work easily, what will in fact work and what is officially supported by IBM. The ultimate arbiter on that last point is the official announcement letter. A similar statement can be made for pricing. There are "procedures" for providing pricing, particularly where discounts are likely to be involved, e.g. educational prices. -- David, working at home and therefore hedging on everything.
