close relative of the Exactra 23
as electronic Wizard from the distributing company Western Auto. Don't be confused with
the electronic Wizard M4995 based on the Montgomery
Ward P8P, the elecronic Wizard M4986 based on the TI-1200
or the elecronic Wizard M4987 based on the TI-1250, this
one is named M4993.
The only differences to the Exactra 23 are the display frame, and the faceplate for the keys.
Dismantling the M4993 reveals a printed circuit board (PCB) 100% identical with the Exactra 23 but to our surprise the display construction looks very unfamiliar to us. We couldn't identify the manufacturer of this board.
The manual provided with this calculators states: TXI 4993A47, distributed by Western Auto Supply Co.
Don't miss the rare Montgomery Ward TXI-8661A based on the Exactra 23 calculator.
