Problema la programator Willem si 27C512

Buna ziua. Am un programator Willem ( AD-MEM03C-paralel ). Am reusit cu el sa citesc si sa scriu mai multe memorii 27C2001 de la ST. Am nevoie sa programez si 27C512. Am facut configratia minidipilor exact cum apare in soft. Memoria este pozitionata in partea de jos a soclului ( GND al memoriei la pinul 16). Urmez aceeasi procedura ca si la memoria 27c2001 dar primesc diverse erori. De exemplu la citire apare in buffer 07 07 07 07, ceea ce apare cand dau citire fara a avea memoria in soclu. Daca incerc totusi sa programez imi da error at 0x000000 chip = 0x07 buffer = 0x02. Ma poate ajuta cineva sa rezolv problema?
