IAN's, U of Waterloo, question about a S-100/ST506 interface board for the Dynex WD505 raises issues which might be of general interest. Any rigid drive with removable media can work on the Seagate ST506 interface, but that interface does not support the removable feature. (Rats, someone lifted my WD file) I believe that the Dynex drive will conform to the ST706 interface; which has a good chance of becoming a standard since Syquest is also going to use it. The new signals include: Change cartridge, Recalibrate, Write Protected, Cartridge changed, and Radial index. As I said, you can do it, it just means you are going to have to be extra careful. You might consider, if uglyness is not a problem, using one of the inexpense winchester conrollers from either Xebec or Western Digital and attaching that to a parallel interface S-100 card. I'm pretty ignorant of S-100 stuff in general for what it's worth. Dan Jones Fortune Systems Corp.
