thank You for answer. second problem : approx 3 years ago i have bought 100 pieces of at1508as with blocked jtag. when selected device in wellon software, i had info about adapter and pinout and connections. I have built adapter and erased all chips with succes. Present version does`t allow me to use my adapter. Please, advice : where can i download older version of software ? I have again the same chips here with need or jtag enabling.
