I am quite sure I have seen this feature on an old nixie-tube Privileg calculator (with horribly bouncing keyboard, but otherwise nice) as well. It must have been from around the same time frame.
Quote:Two new modes are available: SIG and its zero-padded variant, SIG0. Both modes accept arguments from 0 to 7, allowing up to 8 of the most significant digits to be displayed.
Not knowing how the state information for these modes was squeezed into the existing flags record, if it helps to save a bit, the SIG/SIG0 mode could also take the setting of the "LZON/LZOFF" flag 33 into account, I guess.
