Additional Pictures
| The boxy design
of the Sanyo ICC-0081.
|
| It is heavy but still portable.
To us it looks very similar to Sanyo's cassette tape recorders.
|
| The rechargable NiCd
batteries and the amber glowing display..
|
| The calculator brain with
four Sanyo chips (manufactured under license
of
General Instruments Corp.) and the discrete display drivers. Please notice the different date codes of the 4 chips: The LM8001 and LM8002 were manufactured early in 1971, the LM8003 and LM8005 later that year. The backside of the printed circuit boards gives an easy explanation: They were replaced end of 1971.

| The display
board of the ICC-0081 with 8 single gas-discharge tubes.
