On a first glance the Toshiba BC-0801B looks like a shrinked version of the BC-0802 introduced somewhat earlier.
The keyboard with the [+=] key and the constant switch makes a design using the single-chip calculator technology introduced by Texas Instruments possible. A good reason to disassemble the robust machine !
deeper look onto the TMS0112 gives a big surprise !
The chip was manufactured in Japan by Toshiba themselves. Please notice the
small J (Japan) in the TMS0112NCJ
The later BC-0808B reduced weight by more than 50%.
