The Convergent Technology bookshelf unit is a very nice design, with a positive mechanical lock and no arbitrary limits to the bus length. The Amiga expansion port is less successful, because it has no lock and the signal definition was never designed for multiple piggybacks. The original Amiga design would have been much better: basically stacked units with a bus running vertically up the back of the stack, using gravity for locking. It was abandoned because it would have added a several dollars to the cost of manufacturing a $1500 PC. I'd like to see the bus specifics decoupled from the software, so you had some sort of interface that you told "go to unit so-and-so and send this control/read this data". Then you could use a low-cost hookup with ethernet type cables, or a high-speed bus type option, without impacting the software. You could even plug a low-speed adaptor into a high speed bus to hook up your laptop when you get home. If course this would logically be a LAN (um, CAN: Computer Area Network?). > <SIGH> not in my lifetime I suppose. Go get a Burroughs/CT bookcase unit. UHaul uses them here in Houston, or call your local Unisys rep. -- Peter da Silva `-_-' Ferranti International Controls Corporation 'U` Sugar Land, TX 77487-5012 USA +1 713 274 5180 "Zure otsoa besarkatu al duzu gaur?"
