close relative of the Montgomery Ward P8P
as electronic Wizard from the distributing company Western Auto. Don't be confused with
the electronic Wizard M4993 based on the
exactra 23, the elecronic Wizard M4986 based on the TI-1200
or the elecronic Wizard M4987 based on the TI-1250, this
one is named M4995.
Dismantling the M4995 reveals a printed circuit board (PCB) 100% identical with the Montgomery Ward P8P despite the missing switch next to the [%] key.
The TMS0128 located in this rare electronic Wizard introduced in Fall 1973 traces back to the TMS0102 "calculator-on-a-chip" announced two years earlier by Texas Instruments. We know the TMS0128 already from the Canon LE-82.
