HPQDSP-2543

I found some old Cellular one TDMA phones and took the cute looking 8 character dot matrix displays but can't find any spec sheet on them

Can someoe point me to the right direction. Those are made by HP and have markings QDSP-2543 with 24 pins total

I cant find anything similar either so to extrapolate the pins. The 5x7 characters are totally cute and I would really like to get this baby going so your help will be appreciated
