Unisonic 811 with HP LED


Can anyone tell me what the other HP calcs may share the same LED as this calculator?


The HP LED stick is not unusual to find in LED calculators, HP has been "just another supplier" for these (besides Litronix, TI, Bowmar and others)


AFAIK you find them in early Aristo calculators.


Are they the same chips that are in HP calculators?
