       | The Amiga 1000 supported sidecars but later big-box Amigas had
       | internal expansion slots like PCs. The wedge-shaped home computer
       | Amiga 500 supported sidecars. I had an Amiga 500 with SCSI HD
       | sidecar, and a video grabber which was _two_ sidecars (one for
       | the RGB splitter), but the HD and grabber didn 't work together.

         | ;)

         | It's also a reinvention of one-bus-for-different-boxes

         | It could have been made to work, but it would have been speed-

         | right.

         | There are modern systems that still use this sort of modular
         | backplane design. MicroTCA and PXIe are the two major ones,
         | both providing at least power and a PCIe bus on the backplane.
         | MicroTCA supports carrying Ethernet, SATA, and PCIe on the
         | backplane. However both of these are more intended for
         | industrial computing. I could see a consumer variation based on
         | MicroTCA where the chassis has a pre installed controller and
         | backplane. The backplane would be configurable based on the CPU
         | you are running. Higher end CPU would allow for more PCIe lanes
         | meaning more slots, lower end would only allow for a few slots.
         | The computer part is provided by a heavily packaged SBC
         | containing a processor and memory. Mass storage either sits on
         | the SBC as m.2 or as a chassis card connected via SATA or PCIe.
         | You'd have a GPU card connected to a x16 slot (up to two of
         | these for a large chassis). High end sound card sits on another
         | slot. Various interface cards sit on others. You could even
         | drop in an FPGA accelerator card.
         | 
         | This would all probably be too expensive for your average
         | consumer though.

       | While it may not have been coincidental that Fitch's name was
       | Jonathan, another reason is that the Jonathan is a strain of
       | apple, as is the McIntosh (spelled Macintosh for the Apple
       | product).

       | When I was there in '88-'90 I remember seeing a few prototypes of
       | their Mobius computer - an ARM-based system that emulated an
       | Apple II much faster, and was (unfortunately) faster than a Mac
       | II in native mode. It got canned before they ever got around to
       | designing a case for it, but folks who had the prototypes kept
       | them for quite a while.

       | Maybe it wouldn't have been the nightmare the author imagines -
       | Apple figured out how to connect all sorts of gear using
       | Appletalk, and somebody else here pointed out that the chaos of
       | IBM PC compatibles is probably what helped PCs really take off.
       | 
       | This would've used more desk space tho.
