|
Size (approx): |
83mm
(max) x 132mm x 30mm (max) (w,h,d) Weight 144g excluding batteries. |
| Power: | 6.0V DC, 4 x AA size batteries. Also accepts adapter/charger (undefined) through a top side socket on the right. The on/off switch is located on the top side, in the middle and is a three-position on/off/charge. A note on the back warns do not switch to charge with standard batteries in place (in German). | ||
| Case: | Chunky two piece plastic case. Bottom is light grey, top is matt black. Green display filter is flush with the case. The Elite logo and model number is on a printed metal inset panel. The green plastic display filter gives a clean bright image. Keyboard surround is brushed aluminium. The top is slightly tilted upwards, including the back, which causes the calculator to rock, especially with no batteries to weigh it down. The keys are short travel with a soft click and work well enough. | ||
| Display: | 8 digit green VFD display with a ninth used for negative and error indication | ||
| Features: | Basic four function with percentages, square root and pi | ||
| Age: | 1976 | ||
| Manufacturer: | Elite, no other information but back panel's in German. Code number 9025, serial No. 512 06108. | ||
| Comments: | Classic calculator which has a quality feel in the hand. The logic is not too bad but let down by negative square roots and lack of recovery. Imbalance on the desk lets it down. Looks very like some of the Decimo models. The original case is soft black plastic with a flip over top flap and front popper closing. It has the Elite logo embossed on the front. |
| Components: | 1 x cpu; NEC µPD0940C R5X23M 28 pin DIL, 0.6" width black plastic 1 x 9 digit VFD; single tube round face 2 x transistors 5 x diodes 7 x capacitors 9 x resistors 2 x resistor arrays 1 x transformer: B DCT-05 Zebra |
| Boards: | The keyboard assembly (940C-800PKB GK251-4 GICO Japan) sits on top of the battery compartment and is attached to the main cpu board (DW-940) below with a 12-way ribbon cable. The keyboard has a GICO sticker (50.12.4) which date codes it as 4 December 1975. |
| Construction: | Gently prize the front off by using the coin slot at the top. Be careful, you can easily damage your calculator - if in doubt don't try it. |
| Logic comments: | The Clear Entry key (CE) is used to clear an input number; the clear (C) key is used to completely reset the calculator |
| Input overflow is not suppressed: keying in a ninth digit causes an overflow which can be recovered using (CE) | |
| There is automatic constant on all four functions | |
| The negative sign is shown in the immediate left hand digit travelling into the far left (ninth digit) thereby allowing full eight digit negative numbers | |
| The change sign function can be used in mid number entry but not before | |
| An overflow is shown with the result and a C (E if negative) in the far left (ninth) digit and is not recoverable | |
| A divide by zero shows zero and "E" in the far left (ninth) digit and is not recoverable. | |
| Negative square roots are allowed and result in a negative number | |
| No other bugs found |
 |
With the front removed you can see the familiar design of the Decimo-type series: GICO keyboard on top of the battery compartment and half obscuring the main cpu board. |
