I think it is possible to make a replacement for spice LED display when you add some logic gates to the board. The decimal segment can be driven only if decimal and not comma is output. The minus sign must be multiplexed together with other segments. I think there can be used a CPLD or GAL that can do this job. But the smaller size of the QDSP modules gives a worse proportion for spice models, because spice digits are even bigger than woodstocks. The question will be, is there a demand for a spice replacement LED display? If there is i will make the display when i have time. I dont think that the green corrosion will get worse when the calculator is stored in normal dry condition. Bernhard That's one small step for a man - one giant leap for mankind. |
