Lovelly little machine . I have a
couple, along with the 
printer/plotter and the RS232 interface. Oh, and the
technical manual...

I recently bought a Sharp PC1350, which is one of the
'smaller Sharp 
jobbies'. I would claim that's a computer, it can be
programemd in 
machine code (I have the machine language manual and the
service manual), 
it's got the tranditional CPU + ROM + RAM + I/O type of
architecture, 
there's even a built-in CMOS-level serial port (I got the
RS232 interface 
with mine, it's just a level shifter). All I need to find
now is a CE124 
cassette interface (I suspect that's little more than a
level shifter too...)
