Size (approx): |
75mm
x 115mm x 17-22mm (max)
(w,h,d) |
|
Power: |
9V DC, 1 x PP3 size battery, 0.3W. It accepts an adapter (9V 15mA 2.5mm plug centre positive) through socket on the top side to the far right. | |
| Case: | Two piece case with the lower half in beige and the upper in black smooth plastic. Slight wedge shape for hand held or desktop use. A small metallic printed with the company name and model number plate sits in its own recess above the display. The purple display filter sits in a recess and is surrounded by a silver painted escutcheon which is starting to wear on my example. The display is OK but the digits are rather small and have a narrow angle of view. The keys are long travel squishy action and each sits in its own recess with a silver printed label. | |
| Display: | 8 digit red LED with bubble lens and a ninth digit for minus and error indication (on the fat right) | |
| Features: | Standard four functions, percentages and square roots. | |
| Age: | 1976 | |
| Manufacturer: | Sharp Corporation, made in Japan, serial no. 63067740 (sticker in battery compartment). Large patent sticker on the back. | |

Comments:

Slim but solid model. Why is it that all the Sharps I ever pick up need a really good clean? Keys work surprisingly well for the dreadful action. Odd right hand extra digit. The logic is sound but the lack or overflow recovery annoying. The original case is soft black plastic with an open top and the word "Sharp" embossed on the front and "Made in Japan" on the back. |
| Components: | 1 x cpu: Hitachi HD 36370S 6H23
,
28 pin DIL, 0.6" width 1 x nine digit red LED display module with bubble lens: Sharp 6G 0 x transistors 0 x diodes 3 x capacitors 6 x resistors 1 x transformer |
| Boards: | The keyboard assembly is held together with three screws and joins to the cpu board (Ref F1378) via a 17-way very thin ribbon cable. The latter floats free, position by the two screw pillars. |
| Construction: | Remove the two screws at the back. The bottom section will left off when you pop the two top lugs (visible within the battery compartment) and then hinge from the bottom as there are two more lugs there. Be careful - you can easily damage it. |
| Logic comments: | (CE) is used to cancel the last number entered whilst (C) is used to clear the whole calculator. |
| There is automatic constant on multiply and divide only | |
| Input overflow is suppressed, inputting a ninth digit is ignored | |
| Negative sign is shown in the far right (ninth) digit thereby allowing full eight digit negative numbers | |
| Divide by zero shows zero and "E" in the far right (ninth) digit and is not recoverable | |
| Overflow is shown by the result and "E" in the far right (ninth) digit and is not recoverable | |
| Negative square roots are not allowed and show the result and "E" in the far right (ninth) digit and is not recoverable |
