- What sort of transmission medium and CONNECTORS do we have in mind here?
-
- Fibre is, well, Not ideal for short runs IMHO, like runs between a
- floppy disk drive, and cpu would seem painful. Small 25 pin D-sub style
- connectors or even 50-pin ribbon with interleaved ground would seem more
- well suited for short runs
-
- My Idea of *IDEAL* for *ANY* machine would be a system of snap-together
- lego (tm) style blocks with an arbitrary length bus. Blocks would have
- a defined size (Say 6" square?) one block being a "mother-block"
-
- 2 - tier "mother" block

- Each block could be snapped on or off the "bus" at will with all the
- neccessary connection pins / controls on the front or back edges of the
- block. Blocks should/could be stackable, with larger blocks obviously
- on the bottom of a stack.
-
- The Blocks could interconnect in any manner, even see-saw if neccessary,
- and could be fastened together with simple snap-latches (No fripping
- screws). One could just snap on whatever one needed, out to shoebox
- length or stak on top, or whatever.
-
- Juice could/should be supplied by the mother block, with perhaps the
- keyboard interface. The Thickness of a block can be arbitrary in say
- increments of 1 inch. Cooling if needed should be provided
- independently in the blocks that require it by small fans, etc.
-
- Adding a disk drive would involve snapping on a disk block. New video
- block? Snap it on. CPU? Snap it on. Floppy? Tape? Snap, snap.
-
- This type of arrangement would also allow connection of say a ribbon
- cable to another set of blocks.
-
- <SIGH> not in my lifetime I suppose.
