[tech] Switches and hubs...

Another thing we should do is either a 68hc11 or something simpler for
Starfish's boot-up sequence (pressing space at the relevant point).

I've been looking at playing with 12c50[89]'s, the things people make 
PSX modchips out from.  There are some examples easily found on the web 
using them to do random stuff with rs232, and some simple programmer
designs for them (but then, I can't even remember which pin is which on
a transistor anymore, so I might drop the idea...).  If I end up deciding
to build a simple programmer for them it might be an easy option if nobody
ends up doing the hc11 thing (hoping that it is up to being connected inline
and passing most of the signals through, I haven't really looked into this).

David.
