Solid calculator of the no nonsense variety with some useful extra functions. The logic is pretty good but let down by lack of recovery. Original case is soft black plastic with open top and lowered sides for access. |
| Components: | |
| Boards: | |
| Construction: | Cannot find an easy way to open it has the sides are too stiff to easily pop off the internal lugs. |
| Logic comments: | The (CE) key is used to cancel an entry whilst the (C) key clears the whole calculator |
| Input overflow is not suppressed, inputting an ninth digit results in an error which is recoverable using (CE) | |
| There is automatic constant on all four functions | |
| Overflow shows the result and "C" (or "E" if negative) in the far left (ninth) digit and is not recoverable | |
| Divide by zero shows zero and "E" in the far left (ninth) digit and "0." as the result and is not recoverable | |
| Negative numbers are shown with a "-" in the immediate left digit travelling into the ninth digit thereby allowing full eight digit negative numbers |
