OK, folks. Here's my idea which you are free to have (as long as Tek
doesn't come after you for it. But they don't know Amigas exist, anyway.)

Instead of ribbon cable you use a high-quality, multilayer circuit-board
designed with microstrip lines and shielding layers to interconnect the
Amiga main box to your expansion system WHICH HAD BETTER SIT ON TOP OF
THE AMIGA IF YOU'RE GONNA WANT ANYONE WITH A NORMAL SIZED DESK TO BUY IT!!!

The pc-board/interconnect system would have to allow for some tolerance in
the separation between the Amiga connector and the exp.box connector, but
this has been done before - usually with one connecter that "floats" a little
in it's mounting to the box. Getting the signals from hither to yon just ain't
that hard a problem, given that "yon" is only a few inches away!
