Calculators: Handheld: ibico 0892
|
|
Size (approx): | 82mm x
143mm x 27mm (max) (w,h,d) Weight 136g excluding batteries |
|
Power: |
3.0V DC, 2 x AA size batteries. Accepts an adapter/charger (undefined) through a socket on the top side, on the right. | |
| Case: | A strangely angular calculator made of beige and black matt plastic. Dominant brushed aluminium keyboard surround is printed in black for the additional key labels. Green display filter is tilted at about 30 degrees and gives bright clear digits. The keys are square and squishy but still work very well. The ibico logo is raised and printed high gloss metallic silver. | |
| Display: | 8 digit green VFD with a ninth for sign and error indication. | |
| Features: | Standard four functions with change sign, pi, register exchange, reciprocal, square root, powers, logs, trigs, degree/radian, hours/minutes/seconds, three function memory and exponents. | |
| Age: | 1976 | |
| Manufacturer: | ibico, made in Japan, Serial No. 2001217 | |

Strange beast that looks too cheap to have the scientific functions that it does. Odd display that inputs from the left hand side. I find that in use you expect the (F) function key and the (CE/C) clear key to be the other way around. Actually, it grows on you. |
| Components: | 1 x cpu: Hitachi HD36109 6F11
(11 June 1976?), 36 pin DIL 1 x 9 digit VFD display with single flat glass face 1 x transistor 5 x diodes 5 x capacitor 1 x resistor SIL array 5 x resistor 1 x transformer |
| Boards: | The keyboard board floats above the main cpu board (Ref R-36109) and is connected via a 17-way ribbon connector. |
| Construction: | My example came apart easily after leveraging the coin slot at the top. The front came off with no effort. This, however, may be because it has been opened before so try it carefully and if in doubt, don't bother. |
| Logic comments: | The (CE/C) key operates as a cancel entry function on the first press whilst a second press will clear the calculator |
| Input overflow is suppressed, inputting a ninth digit is ignored | |
| Negative numbers are shown with a "-" in the far left (ninth) digit thereby allowing full eight digit negative numbers. However, it is not in the normal central segment but in the upper one. Even stranger, the exponent negative sign is in the middle segment! | |
| There is automatic constant on all four functions | |
| Divide by zero shows "E0." in the far left (ninth/eighth) digit and is recoverable using (CE) | |
| Divide by zero shows "E0." in the far left (ninth/eighth) digit and is not recoverable | |
| Memory store is indicated by a "u" in the far left (ninth) digit |
