- I've seen two versions of this: one successful, one less so. 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?).

- Go get a Burroughs/CT bookcase unit. UHaul uses them here in Houston, or
- call your local Unisys rep.
