Quite well made compact calculator, however, the colour scheme is a bit dull. It has a similar case design to the Sanyo CX-8136. The logic is OK but the lack of error recovery. Unusual symbol for the sign change key. |
| Components: | 1 x cpu; NEC D1803C E03219, 28 pin DIL, 0.6" width 1 x 9 digit VFD display; single flat glass face 2 x transistors 3 x diodes 8 x capacitors 3 x resistors 1 x transformer: W523A |
| Boards: | The main cpu board (A-1 R-4172586) sits loosely above the keyboard assembly and is joined by a 23-way ribbon connector. The latter is attached to the front with four screws. |
| Construction: | Remove the single screw from the back. Gently lever out the sides so that you can pop the two side lugs about 2/3 the way up - squeeze in the front section to help. Then gently hinge the rear section about the top to release two more lugs - Quite difficult to if in doubt do not force it. |
| Logic comments: | The (C) key is used once to cancel an entry whilst a second press clears the whole calculator |
| Input overflow is suppressed inputting an ninth digit is ignored | |
| Negative numbers are shown with a "-” in the far left (ninth) digit, thereby allowing full eight digit negative numbers. | |
| There is automatic constant on multiply and divide only | |
| The change sign can be used in mid number entry | |
| Divide by zero shows the result and “C” in the far left (ninth) digit and is not recoverable | |
| Overflow shows the result and “C” (or “E” if negative) in the far left (ninth) digit and is not recoverable | |
| Negative square roots are not allowed and result “C” in the far left (ninth) digit and is not recoverable | |
| There is indication of memory store: the decimal point of the far left (ninth) digit lights up |
