DATAMATH  CALCULATOR  MUSEUM

Additional Pictures 

 

 The internal construction of the Canola LS-1 is centered around the
TMS0106 single-chip calculator chip and a Hitachi display module.
The 4 black modules contain the display drivers (6248, 6249) and
the clock driver (5307) of the calculator circuit.

The robust keyboard of the Canola LS-1 uses Reed-contacts
excited by small magnets attached to each key.
