   Do you really mean a total of 8 bits of storage, or do you mean storage   
   addressable by 8 bits (thus avoiding the need for any 16-bit registers   
   or other registers bigger than 8 bits) ?   
      
   With only 8 bits of storage, you are basically talking about a simple   
   programmable state machine or programmable logic, not a programmable   
   computer. (There are programmable logic devices available with such   
   small numbers of storage bits - the GreenPAK family is perhaps the best   
   example.)   
      
   The smallest device I programmed in C had no ram at all, but it had 32   
   8-bit registers, a three-entry return stack, 32 bytes of eeprom (IIRC),   
   and I think 1k x 16-bit flash for the program.
