   We already established earlier in the thread that they   
   don't exist and noone wants to make them, so you've   
   now repeated that.   
      
   And that's fine. I was simply asking the question. If   
   the hobbyist (or whatever) market is too small that   
   no-one wants to pre-make these computers, so be it.   
      
   Note that it doesn't necessarily need to be "mass   
   production". I was just after pre-made.

   I take that as "none of them are applicable, it is indeed   
   possible to build such a laptop - just no-one has so far,   
   and I don't see market potential personally".

   I could demonstrate it in qemu if you think it isn't possible   
   to get disk sectors via the serial port. There used to be   
   something called the "$25 network". I didn't use it myself,   
   but that may have done the same thing. Probably more   
   robust and feature-filled than I would write.
